View Full Version : [kubuntu] Intrepid x64 with Intel Wireless 5300 AGN wlan Cannot Obtain IP unless next to router

March 14th, 2009, 10:50 PM
Hello. I recently bought a Sager 2096 laptop, which contains Intel Wireless 5300 AGN wlan hardware. I have kubuntu 8.10 x64 installed on my system.

The problem I am having is that when I try to connect to the Internet via wlan, I cannot connect unless I am right next to the router. I know that the router works, as I can connect to it with other wireless devices from a distance. In addition, I know that this wireless card works, because I have tested it running my second operating system on my machine, Windows 7 build 7048 x64, and using the drivers that came from the Intel driver site. Currently, when I try to connect to my unsecured public home network, my wireless manager cannot get past "Obtaining IP Address".

Here are some more infos:

The solutions I have attempted include switching to wicd instead of knetworkmanager (same results), updating and reinstalling drivers (same results), and changing settings such as the channel on my home wifi router (same results).

It is important for me to solve this within the next 5 days, as I am leaving the country and want to be able to connect to what little internet I may have at my destination, some of which could be wifi.

I can connect to my wireless network when I am (literally) on top of my wireless router. I cannot connect at distances more than 3 meters. However, I still can read the signal of the network from a distance. My problem is that I cannot obtain an IP address, or at least that is where the problem occurs.

Thank you very much

Wow, I have the same problem. I bought a new modem/router because my old one (e-tech) got broken, the new one is from levelone, wbr-3600.

Well, I installed this new router and configured it with my desktop computer (windowsxp). Then I started my laptop that has ubuntu 9.04 and I tried to connect to my new router, but it didn't work.

So some time later I took a modem/router (philips) from work to test it here at home. And I could connect to that router without a problem. At some point I was in my basement where the routers are standing and my laptop was connected with a utp cable to my new levelone wbr-3600 router. I unplugged the cable and selected the ssid from that router and after some time it connected.

Then I went to the kitchen and I still had a very good signal and I could do anything, I never lost signal but if I selected the other router (philips from work) and wanted to go back to my new router (levelone) then it didn't work. BUT if I was standing next to my new router in the basement then it connected.

I have an Intel Wireless 4965 AGN card in my laptop and I also have this problem. It's strange that a windows computer can connect without a problem... I'm still searching for a solution but haven't found one.

Same problem here with an Intel iwl4965 AGN chipset on a Dell XPS m1330 and Kubuntu karmic!!
Anyone has found a solution? please...

I bought another card, an atheros card and I thought it was a ar5008 (I'm not at my linux comp at the moment). And the problem was solved.
