Bug Description

Ok I am typing on my old laptop. I have a strange problem with my new Dell xps studio 13. The Wifi driver on it is not working correctly. I can get my wifi to work but for some reason the signal is EXTREMELY weak. I can get a great signal when I boot into windows. So I know it is not a card issue but rather a driver issue. Even then the signal on my old lap top is really strong. On my old laptop. I have 4 out of 5 bars. On my Dell xps I have next to NONE. It takes like 10 mins to even get it to get a lock. Does anyone know what I can do to fix this. I trying to use Ndiswrapper to install the windows driver. But I can not figure out how to do that. Because it always says driver not working. So I may not be stearing Ndis to the right place. This problem is also present in Kubuntu too.

This is for Ubuntu 9.04

This the card I have that is listed on the Dell site.

Wireless Networking Cards
Dell Wireless 1510 802.11n Half Mini-Card

Any suggestions?
Thanks

I was able to get this to work by enabling the proprietary drivers and making sure that the goddamn wireless switch on the physical machine was set to "ON". I had no idea this machine even had a switch, nor how it got set to "OFF" but it is a laptop, I stuff it into and out of my backpack any number of times during the day.

Nynoah, can you confirm that your wireless switch is set on? on my box, it's on the left hand side panel, right next to the HDMI input.

Same problem here. Dell XPS Studio 13, Ubuntu 9.04 64-bit and I am sitting by my WRT300N (v2) AP. While Vista connects me to it at 130 Mbps, I can only do it at 54 Mbps.

Besides, signal power is only 76% (and I am only 2 metres away), while in Vista I get 100%.

Can anybody please provide me a solution for this? How are "proprietary drivers" enabled, Jon47?

Thanks in advance!

I have similar problem. On my HP laptop i get signal 40% and on sony vaio only 20-24% at the same location.Both have intel b/g type wifi device. If boot into vista the wifi signal boost to 60-80%. Why ubuntu shows always shows a low signal in every laptop.

I also have a similar issue. I have a Dell XPS Studio 13 with Ubuntu 8.10 on it. The WEP wireless connects, but
1.) The signal is low.
2.) Once you manually disconnect the wireless, it does not re-connect. It keeps asking for the WEP key but does not connect. After a reboot, it connects within a few minutes.
3.) I get an IP on wlan0 but its not able to ping to the default gw. There is no such problem when I connect with the wired n/w. The router is fine as I have 3 other computers running.

And again. Ubuntu 9.04 64-bit, WPA. Not tried anything other than that but have the same problem with weak signals. Haven't seen anything over 50%.

Same here. Ubuntu 9.04 32-bit. Dell XPS Studio 13. Came with Vista which I booted once, entered WPA key and connected without no hassle whatsoever. Now running Dell's 9.04 iso(tried regular too). After reboot I get two green dots with WEP but then it fails almost every time. I can get connected if I'm lucky, but it usually disconnects after a while.

Can post logs if you tell me what you need(not very Linux savvy)

Confirmed, Dell Xps Studio 13, Ubuntu 9.04 64-bit, Dell Wireless 1510 802.11n Half Mini-Card, same issues ...

Good damn, this is so annoying ...

I resolved my issues by installing linux-backports-modules-2.6.28-14-generic. My connection has been near flawless since.

Guys, my wifi is fine now. There are 2 problems with it. One with the driver itself, another with the network-manager. See my comment here:

This seems like bug #289356

Can you please test Ubuntu 9.10 (karmic) and if you still have this issue, please re-open it as confirmed.

Issue is still present in 9.10. Even with backports turned on. Basically what I think the problem is, is that Ubuntu is not properly using the Wifi. Like it is not recognizing the inputs for the antenna or for some form of booster. signal is 50% less on Ubuntu thant windows.
