[SOLVED] Extremely unreliable wireless connection in Waldorf

R3nCi · 2012-12-08 18:02:06

Good morning,

I completed an install of Waldorf last weekend, and am very happy in all respects but one: it seems impossible to connect to and use a wireless internet connection without constant disconnects.

Each time that I attempt to connect to a wireless network, unsecured or otherwise, the connection is made and it works OK for a short period of time. Then, suddenly, loading-speed will decrease drastically to the point of becoming unusably slow. Soon after this happens, the connection will be lost.

Waldorf will then attempt to reconnect to the wireless network; sometimes, the re-connection will be made successfully, after which this cycle is repeated; otherwise, the 'connecting' indicator will loop for a while and then stop trying.

I am extremely happy with #!, other than this one flaw. If this can be fixed, I will be extremely happy; does anyone have any suggestions as to where I might go from here, beyond updating my system (sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade)?

Regards,

/L

I did another set of updates and it seems to be working better than usual. Nonetheless:

lawrence@Mona:~$ lspci -knn | grep -EiA2 net

BCM4312

(That's my cue.)
What model router? Try the fix here.

Thank you very much for your help, pvsage.

The router to which I am attempting to connect at the moment is a Linksys WRT300N.

I tried running the commands shown in the above fix-post exactly as written; after rebooting, nothing seems to have changed, although it is possible that I may have entered something incorrectly.

Thoughts? smile

pvsage · 2012-12-09 06:57:39

Please

cat /etc/modprobe.d/b43.conf

and post the results here, though I'm pretty sure this solution won't improve communications with a Linksys router - those are generally well-behaved. (The router I had trouble with was a Netgear.)

Also, it's entirely possible that this fix no longer works in Waldorf; it worked with Statler, but I no longer have the netbook with which I used that fix. I think The Good Doctor is probably going to be your best resource here.

Looks fine to me, so I regret that I'm out of my depth here. Good news - we've ruled out a problem, and found a solution that doesn't apply here. (It should be safe to remove that file, by the way.)

The Good Doctor should be back shortly.

R3nCi · 2012-12-12 17:35:12

I should add that I am experiencing none of these issues when connected via a Netgear wireless router. smile

Try installing a more recent kernel with smxi: either a liquorix kernel or an aptosid one ( towo kernel).

R3nCi · 2012-12-23 04:46:25

My posting of this issue on LinuxQuestions netted a resounding (although thoroughly unhelpful) "switch to another distro!"

I'm sticking with #!, end of story. Further suggestions from the folks here would be very much appreciated. smile

edit: whoops, see below.

Did you try this suggestion? Any luck?

Hm. I hadn't noticed that post before... that was a bit unintelligent of me, wasn't it? tongue

I'll give this a try sometime over the next week or so and report back. Thanks to both of you!

Well, I still haven't actually done this yet. I'll get around to it soon, but not until my dad gets his laptop fixed. He has been borrowing mine for the past while because his is out of commission due to a hard drive failure.

This is due to the b43 driver not fully supporting some WiFi chipsets like the BCM4312 properly. You can switch to the propietary, original Broadcom driver where everything will work as expected:

http://wiki.debian.org/wl

Although, note this is a propietary driver, if you care about opensourceness. It's very easy to install, though. It will also allow you to connect full-speed to 802.11n routers. (probably that's the issue)

zenitra,

I have followed the instructions contained in the wiki article. Wireless seems to be working well for now, aside for occasional fluctuations in signal strength.

Assuming this works, thank you very much for your help! If I start encountering other issues, I'll follow the instructions under 'known issues' in the article and/or explore other solutions.

Thanks again smile

The problem has been solved completely. No more wireless dropouts or any other issues. Thank you so much!!!!!!!! big_smile

R3nCi · 2013-01-12 03:28:02

I can now verify, through several hours of use, that the wireless problem is solved. Thanks again! smile

/solved
