Ubuntu Networking :: Edimax Router Keeps Crashing?
Dec 27, 2010
The issue is that after a while the lan side doesn't work any more (I don't know whether the wan side still works, but I assume it doesn't)
First we had BR6214K for which the transformator turned out to be broken (at least after a few years it gave 7 instead of 12 volt), only have it's replacement die shortly after. But the issue since the beginning was the network disconnecting every two to three days. Restarting the router solved the problem almost every time.
Now we have the same issue with a brand new BR6226n. This time the disconnection occurs almost every day. Restarting the router has so far worked every time.
Is this more likely to be a router or a computer issue (maybe a broken network card in one of the computers)?

I have 2 PC's : a desktop and an notebook(IBM).On my desktop i have Windows 7 and Ubuntu 9.10,and on my notebook(IBM) is Windows XP SP3. Both of the PC's are conected to internet over an PPPoE conection in Windows thorugh my router(EDIMAX).
My desktop has the following :
IP adress : 192.168.2.100
Subnet mask : 255.255.255.0
Default gateway : 192.168.2.1
Preferred DNS server : 192.168.2.1
[Code]...
When i boot to Ubuntu 9.10 i dont have internet...but if i restart the PC and enter in Windows 7 there is internet,and is the same connection,the same adresess. How can i make the connection in Ubuntu 9.10 with the same adress,i mean like is in Windows 7?

I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.

I'm going round in circles with this as I'm just not very good at using the command line in Ubuntu. I've bought an Edimax EW-7811Un nano USB wifi adapter, and I'm really cheesed off at the moment because I can't get it to work on my laptop. I've got Ubuntu 10.04 on it. I really want this tiny dongle to work with my computer. Ubuntu is much fats than Windows, and I use it all the time, but my current wifi donlge is an old big monstrosity!

Got an Edimax 7717un USB dongle for my Acer aspire 6930 (built-in WiFi is broken). It finds access point OK, but fails to setup with DHCP. If I put in manual IP config, I can ping OK, but I cannot browse web (or even my router's setup page). I get same behaviour on a home brew desktop.
With manual IP config, ping to my router works fine (and very fast, as does ping to 2 or 3 internet web sites. I can traceroute to internet web sites OK as well. With web browsing, if I wait a few minutes some bits of the page may arrive. With connection set to DHCP, Wicd shows WiFi connecting OK, but DHCP setup times out.

I have Maverick Meerkat running perfectly on my laptop and have loaded as dual boot onto my old XP pc as well, I'm quite a newbie and working my way through Ubuntu for Non Geeks.
Problem - apparently this PCI card - Edimax wireless N PCI 7727in card is supposed to work out of the box, it came with the Ralink drivers for Ubuntu RT2860.
the network manager finds the homehub and tries to connect but just continually tries and never actually does it, the card works fine with XP so i know it's not faulty.
if it was a driver fault would the card be working at all? would it try to find the network manager?
I bought this card as previously i was using a Dlink DWA-140 and gave up trying to make it work, this card is advertised as Linux compatible in the Ubuntu forums list and on the card.

I have two PCI network cards: Wired - Successfully connects to the internet and removed from the outputs describes below. Wireless - A new and works well in WinXP - Edimax EW-7711ln: problematic - can't connect. Manufacture says it's supported in Linux. Although in it's site it doesn't have any linux driver to download. The XP driver contain 2 .cab files that cannot be accessed using unshield/cabextract so I guess "ndiswrapper" is not an option. Other Linux disrtos also didn't recognize the wireless as well. Below I added as much information as I could get.

Finally took the plunge and upgraded my ubuntu studio to karmic from jaunty. I seem to be experiencing a problem many have, being that my wifi card (edimax) which worked on my previous distro is now not working at all. I've done a lot of research and found the problem seems to mainly be with broadcom cards, and have tried a number of things relating to those that have worked for others, with no luck.
My problem seems to be not that the drivers wont activate or anything like that, my problem is that under hardware drivers nothing appears at all. I have no drivers present, where most people are talking of 3. i have not found anyone else with this problem. My problem is compounded in addition by not being about to use a wire connection at all.

I have just upgraded to 11.04 from an earlier version and most things are working better, if a little slower. Had to remove pulse audio to get any sound. Wifi with Edimax 54G Pcmcia card used to work fully, but now only works on mains, not on battery.Suspected power management but iwconfig shows it is off.Dmesg revealed that the driver had crashed in rt61pci.

In system log i get:

It seams like a physical hardware problem but i cant find any physical fault on the card itself.

I have just installed Fedora 10 on a Dell Inspiron 530. I was delighted to see on the very first boot into the system that my Edimax RT73 USB stick was recognised by the system as it was offering a selection of wireless networks to connect to. But oddly, my own network wasn't listed there. I created a new network and entered the network id manually. Once it was in the list, I checked the radio button and saw a message that I am connected to my network. But after a few seconds the network icon disappeared.
I rebooted the system and again went through the same process with the icon disappearing.
I have an Edimax wireless access point with DHCP enabled. The security is WPA2 Personal with AES.
Vista is also dual booting on the same machine and working fine.

After purchasing few wifi-usb-dongles for my jaunty and lost many hours, i had no success in bringing them to operate as master or ad-hoc.The devices were Belkin, Level1, and a TP-Link 620 Though the Belkin could work as ad-hoc, but very often disconnects due to buffers issue (though I couldn't build the zd1211b driver for jaunty and it seems that no one can really help with that).
Now I would like to consult with you ahead regarding new potential devices, whether you know it operates as master mode or ad-hoc mode under jaunty (9.04)?
My concerns are regarding:
1. Edimax EW-7318UG
2. Edimax EW-7318USg
3. Edimax EW-7711UMN
4. Edimax EW-7711UTN
5. Edimax EW-7311USN
6. Edimax EW-7717 nMax
7. Edimax EW-7718 nMax

Just installed Ubuntu Studio 10.04 and everything seems to be working nicely except I have no networking.
The card does not appear in the Network Settings GUI. The only 3 tabs I have are General, DNS, and Hosts.
A screen grab is attached.
I'm a long time Windows user trying out some of the best Linux creative apps I can find. So, Ubuntu Studio was a no brainer. I checked the manufacturer's site for linux drivers and they are available, but I don't know how current. (Edimax site, not RaLink's site.) I opened the file and it looks like it needs to be compiled and installed to work. Something I know almost nothing about. The card is listed as supported in this forum for Ubuntu 9x but I can't find information about it for 10.04
PS. I have no networking on the system but I can transfer files via USB flash drives if needed.
Some System info:
Code:
1 ) Machine Brand and Model (PC/Laptop): Dell Precision 650
2 ) Wireless Brand, Model and Wireless Chipset: 03:0c.0 Network controller: RaLink RT2561/RT61 802.11g PCI
3 ) check interface: robert@ubuntu:~$ ifconfig

I've currently got the beta of fedora 12 installed, hope to upgrade that once the final release comes out. I'm having so many problems getting wireless to work. I've got a edimax ew-7711utn wireless adaptor. It doesn't work. Really what I want is to take it back and get a wireless card that will work.

I have just purchased an Edimax EW-7128g with Ralink RT61 chip and physically installed it in a system running CentOS 5.2. Trying to follow the installation instructions, I get the following:

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

I have just installed an Edimax EW-7612PIn PCI-E Wifi card which has an RTL8192SE chipset. This chipset is not supported under current F15 kernels so I have installed the driver and firmware from source and have that working fine. The driver can see the card and I can issue 'iwconfig' commands successfully enough to see my Wifi network.
The problem I have is that I don't understand the relationship between iwconfig and wpa_supplicatant and as I'm running a headless F15 server I cannot use the NetworkManager GUI to help me. I should also note that the Wifi network is using WPA2-Personal encryption.
This is what I have done:
Configured /etc/sysconfig/network-scripts/ifcfg-wlan0 with what I think are reasonable values (based on google searches), including the ESSID, TYPE as Wireless, etc.
Configured /etc/wpa_supplicant/wpa_supplicant.conf, including using the key value returned from wpa_passphrase.
Arranged for wpa_supplicant to run from boot, using chkconfig.
However when I run 'ifconfig wlan0 up' I get the error message 'link is not ready' and indeed looking at the output from 'iwconfig wlan0' there are no configured values. I also understand that some values are configured by iwconfig and others by wpa_supplicant, however it's not clear what.
How do I permanently set iwconfig values?
How do I configure wpa_supplicant?

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.
