Ubuntu Networking :: Computer Unable To Find Wireless Signals Despite Right Next To Router
Apr 4, 2011
just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I have a Belkin Wireless G F5D7230-4. I was attempting to configure a wireless card on another computer on my network when it froze during the reboot phase after making settings adjustments. The wired connection is fine, except on that computer that I was making the adjustments from. It won't connect at all. I plugged a friends netbook into the same wired line and it connected. Also there is no wireless signal on any laptops. Mac, Win Linux, don't matter. I tried all the various methods of resetting to default but still when I try to access the router's config page @ http://192.168.2.1 I get the error Code: The server at 192.168.2.1 is taking too long to respond.

I'm trying to make my wireless router always give me the same ip address every boot (192.168.1.100). I do not have a static ip address from my isp.
Everything I've tried from online help has made my internet break and I'm not even sure what exactly I should be searching for on google.
Ultimately, I'm trying to get my wireless router to forward ftp requests to my computer which shares the network with an xp machine. I think this is the way to go about it.

To start off I have a Rosewill rnx-n2x wireless adapter and a Dlink 4500 router. The problem is, the wireless network manager detects every wireless router in the neighborhood, except mine. I see this persons, and this persons, but no "My router Not yours". I even tried doing the hidden network setup and still nothing.
I have read that the rnx n2x isnt supported by linux, although I've seen solutions to make it work (which didn't work, mkdir command kept getting denied during make) link to what I'm talking about: [URL]. What I don't get though, is that if the rnx n2x isnt supported by linux, wouldn't I not be getting my neighbors connections to begin with?

I have had a router die on me and have bought another (maybe a bad buy!) The new router is Linksys WAG120n. Ethernet is fine. Laptop wireless adapter is Atheros AR5009 802 11a/g/n. I have setup a wireless connection but it is not connecting to it. I have checked the router settings and these seem to be OK! I'll try to give any details required.

Firstly, the actual problem I'm having is that when I start my computer (netbook) up in the morning and try to connect to the router (wirelessly) it just... doesn't work. I've used it before, at full signal strength, and it was completely fine. It never disconnects me or anything - but if I shut down my computer, like I do overnight, when I start it up again often it's hardly getting a signal at all (or so it says) and when it tries to connect it makes the connecting animation and occasionally flashes to a circular thing like firefox's loading animation. Eventually it just fails.
I try restarting my computer, but it doesn't seem to help. The last time, I had to wait until the signal looked "full" again, then delete the settings in "edit connections" for that router and only then would it let me log in again, even though I was using the same password from the same computer (even in the same place). That only seems to help when the connection looks "full" though, and even then, not always. Normally I'd try resetting the router, but I can't because it's locked in the next room (I rent a room here and the guy with the key is rarely around) but honestly I don't think the router is causing this, for a few reasons:............

barley got it today in fact, have my laptop dual booted running Win7 and Ubuntu 10.04. I haven't worked with the terminal at all so i have no idea what I'm doing with this. I'm having a problem connecting to the wireless Internet. It has theicon at the top but doesn't recognize any signals. Works fine using land line though. My laptop has the wifi on/off button on it but that doesn't seem to be doing anything

I can't pick up any wireless signals while running Ubuntu 10.04, but while running Windows 7, I pick them up. I have the feeling it's because of a missing driver, could anyone help me solve this issue?

I had windows and 8.10 earlier and now have single boot 10.04 !
1.) I can see wireless networks only after I am connected to the router through wired ! I guess its some thing to do with me activating ifup and ifdown, when my wired connection stopped working as i was trying to install wireless drivers.
2.) Even when I see wireless networks, i cannot connect to any of them.
I tried various things for a whole day trying to fix it and i doubt if i screwed up some thing that was running good.

So I just loaded ubuntu 10.10....and it works great...except for my wirelessi've got a broadcom b43 ...i went into system, administration, download additional drivers and downloaded/authenticated a b43 driver, but my machine (hp dv4405) does not recognize any wireless signals. The wireless light on my computer doesnt turn on (there's a button to turn it on and off) anyways...it's annoying. I guess broadcom recently released some open source drivers, but I'm having trouble sorting through all the info

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.

I have been running F13 since it came out, with the wireless working fine since I got it working (using the RPM Fusion repository, broadcom-wl-5.60.48.36-1.fc13). Since I updated software (without reading what was to be updated), yesterday, I am unable to even find wireless networks, although I am, as you can see, able to access through eth0 It is not a hardware problem, as I can not only find them, but access them on Ubuntu 9.10 live disc. Below is my lspci

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 normally connect to a free wireless project, and did have a Windows box until yesterday when I installed Fedora 10. When I was using Windows, I was able to connect to the unsecured wireless network. Now on Fedora 10, the wireless card is working and is able to pick up signals but the signal strengths are markedly decreased and I am unable to see the network which I usually connected to.I really don't want to go back to Windows.

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 am unable to access wireless network from my notebook. My configuration is Dell i5, 4GB RAM and 1397 W-LAN and I have F13. I can still access Internet through Ethernet using a LAN cable but the network monitor doesn't show list of Wireless networks which my room mate's windows 7 machine easily detects.
If anyone needs more info please provide me the steps to perform to find that out

I want to use a linux computer as a router in a medium sized organization. we have around 10MB internet and we have to distribute it among some 2000 pcs. so i have a computer available, and wanted to do some bandwidth management on it (with tc). want to know if this is possible or if it might create a bottle neck.(the internet is coming from 2 different ISPs). Using a router is not an option, coz our organization is happy with what they get currently BUT since its unmanaged it has lots of problems, and also there is no money for buying a router

I have read in a forum that a computer can have the same MAC Address with its router in the sane LAN but how is that possible? Isn't every MAC unique? Also I have not understood, when we send a packet to a PC that is not in our LAN the packet should have the IP Address or the MAC Address of the computer that we want to send?

wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
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.

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 have a desktop computer (Ubuntu) connected to one of the LAN ports of the Cradlepoint MBR1000 router via an Ethernet cable. I also have a Verizon mobile broadband USB modem (USB760) plugged into the USB port of the Cradlepoint router.I also have a laptop (Ubuntu) with a wireless wi-fi adapter (802.11g). The laptop also has an Ethernet card but I'm not using it. The desktop computer does not have a wi-fi adapter, only the laptop does.
With the above setup, I have Internet access to both the desktop computer as well as the laptop computer, which I am well pleased with.Is there a way I can have file sharing between the desktop and the laptop, or at least ping between them, the way I have it set up? I can't use the ad-hoc method because for that to work each computer needs a wi-fi adapter. The router is using DHCP but can also be configured manually.
