Networking :: Attaching Switch To Router Disables Wireless?

Dec 24, 2009

I have a wireless router with a 4-port switch built in. The router is a Linksys WRT310N. I have more than 4 devices that I would like to connect through wired connections...so I have an 8 port switch that I connect into one of the 4 ports on the back of the router. Whenever I do this, the wireless functionality stops working! To get wireless back, I just have to unplug the gigabit switch (and unplug/plug in the router) and wireless is back up and running.

It doesn't seem to matter which port I plug the switch into so that isn't the cause of this. Also, I can connect up 4 devices where none of them is a switch (i.e. 4 computers) and wireless still works just fine -- so it doesn't seem to be a problem that there are 4 devices attached. when the switch is connected to my router, the devices behind it work just fine. However, the wireless devices all obtain 169.254.*.* addresses so clearly the clients are failing to obtain an address from the router (the DHCP server).

Ubuntu Networking :: Laptop Has A Switch On The Side That Enables Or Disables The Wireless Card?

Jan 14, 2011

I recently switched from windows xp to ubuntu and have been very impressed so far. However, I've run into a bit of a problem. My laptop has a switch on the side that enables or disables the wireless card and every now and again its inevitable that someone accidentally switches it off. When I had windows xp all you had to do to re-enable it was to go to the device manager and turn it back on however ubuntu apparently doesn't have a device manager. so I need help. my wireless card info is05:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Networking :: Finding The Router / Switch And Wireless AP?

Jul 24, 2011

I have two laptops and a desktop. At any given moment I would like the desktop to be able to download a file over WAN at maximum speed while one laptop does the same over wireless and the other laptop shares files either wired through a gigabit switch or wireless over wireless G or N. Is this too much to ask from a router/switch/wireless AP combo unit with a single processor? I'm thinking it's at least a lot. What if I ran the modem into the WAN connection of a good router. Then connected a separate wireless G/N access point and gigabit switch to the LAN connections of the router? That seems to me like it would relieve some of the bottle necks I would encounter with the scenario described above AND allow me to upgrade each unit as needed.

Ubuntu Networking :: Installing Broadcom Wireless Driver Disables Ethernet?

Jan 2, 2010

I have a Dell Inspiron E1505, which has the Dell Wireless 1505 (Broadcom) card. To run the card, I installed the Broadcom STA wireless driver, which seems to activate the wireless card OK. The problem is that once I installed that driver my onboard Ethernet card was deactivated (and yes, it is enabled in BIOS). I had to remove the wireless driver to get the Ethernet back. Does anyone have ideas? I haven't found this problem listed elsewhere. I am running Ubuntu 9.04 with no other problems.

Ubuntu Networking :: Use One Wireless Router To Connect/detect To Another Wireless Router?

Aug 1, 2010

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.

Networking :: Cannot Ping Wireless Router Or Access Router Settings - Wireless ?

Jun 9, 2010

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.

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

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?

Networking :: Network Setup - Router - Wireless Router Card ?

Apr 24, 2010

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?

Networking :: Layer 2 Switch - VLAN Router To Network

May 15, 2009

Our ISP provides us with Layer 2 hardware (Modem?/Switch? (Hatteras)) for our leased line and internet access. I have been told that I should set up a VLAN capable router to separate the internet traffic from the internal traffic. I found that linux is capable of VLAN routing. Nice!

I have setup opensuse 10.3 put in two NICs and did the following
vconfig add eth0 10
vconfig add eth0 20
ifconfig public.ip.add.ress netmask 255.255.255.252 eth0.10 up
ifconfig 192.168.0.1 netmask 255.255.255.0 eth0.20 up

Plugged this NIC into the HATTERAS hardware (with a straight cable), and thought that this way I should be able to ping the public gateway or any ip out on the internet. My ISP is telling me that I should create a VLAN trunk to be able to 'use the internet', but as I understand in linux if I create any number of VLANs on one NIC they are already trunked. I also got the info, that the traffic is tagged, and I can separate the traffic reading the tags. I already read that some NICs are not able to VLAN because they are not able to handle the increased packet size.

Also that the MTU setting is important (dono' the exact value though, only that its important). I thought that a linux machine can act as a router and firewall in such a case, because proprietary switches/routers use linux as embedded os. This is my first meeting with VLAN so if this whole post does not make any sense or you think that I just need to RTFM more then tell me! I also have some (3) Dlink 3226 Layer2 switches around, but I think it would be waste to use a 24 port switch on this subject.

Ubuntu Networking :: Wireless Card - WEP Encryption For Wireless Router Not Allow Me To Connect

Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.

Ubuntu Networking :: Tenda W322P Wireless Card Crashing Wireless Router On Connect

Jun 30, 2011

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.

Ubuntu Networking :: HP Pavilion Wireless Enable/Disable Button / "Wireless Disabled By Hardware Switch"?

May 11, 2011

I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.

I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.

Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.

As my only network options are wireless, this has become a substantial inconvenience.
----
EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working.
-----
EDIT 2:
found this thread:"Wireless disabled by hardware switch" bug? - Natty
seems to be a similar issue. I'll be following how that one develops, too.

The problem is i cannot access wifi. The network manager says the wireless is disabled by hardware switch.

My hardware switch for wireless (on the laptop) is infact ON.

[Code]...

During natty installation (it was a fresh one) i had ticked for third party installations but had no internet running at that time. now the additional drivers under hardware in system settings shows nothing. just blank. NO MATTER WHAT I DID I HAVE COME TO THE FIRST STEP AGAIN. MY WIRELESS IS DISABLED BY HARDWARE SWITCH. where is this switch & how do i switch it on (if thatz so easy.) but all the solutions given in other thread were specific to some system or condition and mine somehow did not match.

Ubuntu Networking :: Wireless Freezes Computer - Switch To Ndiswrapper?

Jul 28, 2010

Since I upgraded to Lucid, I am dealing with serious instabilities related to my wireless card. What happens is that when there is a lot of wireless activity the computer freezes. It is a complete freeze, the mouse stops moving, if something was coming out of the speakers it keeps echoing, and the only solution is to turn off the computer. The bug seems to coincide with the one listed in here

[URL]

My wireless card is Intersil ISL3890/ISL3886. My whole computer is an HP z555. I'm thinking that is should be a bug in the wireless adapter driver, which is p54pci. The only solution I can think of is to blacklist it and set up ndiswrapper. I am not very comfortable with this solution since a native linux driver should be better than ndiswrapper.
