I don't know what the answer is, but you could have a look at your logs to investigate into the issue.

Re: WIFI dies when transferring big files over the network

I had same problem with ipw3945 on Dell 640m under 8.10 kubuntu yesterday
and this problem persists all the time: LED is sometimes fixed  (on) sometimes flashing
the newest kernel, 2.6.27rc_whatever - I don't remember now

I repeaded copy and worked out but this driver has problems there

You know this happens to me, too?  ipw3945 on Dell Vostro 1500.

I got around it by scp-ing to the internet-facing address of the computer I was sending to, rather than the intranet address.

Re: WIFI dies when transferring big files over the network

I have an issue with wireless as well with this driver (iwl3945 - dell xps m1330 & inspiron 1720).  I moved both my laptops from FedoraCore 8 (wireless worked solid).  Ever since moving to arch wireless is laggy and I can't keep a constant rdp session at all.  Only thing that has changed is the OS.  Everything else is working like a dream.  Anyone have any ideas on the issue or know when a newer driver will be released?

I have the same problem using the ipw2200 driver.

Re: WIFI dies when transferring big files over the network

Anyone on the dev side of arch having any wireless issues?  I have tried with atheros/iwl3945/iwl4965 cards/drivers and all have the same problem as described above.  It is getting very irritating but I don't want to switch from arch.  I have been using it all of 2-3 months and love every bit of it except wireless.  Ethernet does not have these issues.  What else can I do to help solve the problem?

Seems like high priority bug to me.

Re: WIFI dies when transferring big files over the network

I guess we shall see. I can't imagine we are the only 7 with these issues.  Mine is mainly just lag... and overall slowness.  I hope to work through this.  If it lasts much longer I will have to revert back all 3 of my lappies to FC which I really do not want to do.  But on the lappies i connect via wireless 90% of the time and need it to work. 

By the way how are you guys configuring your wifi?  I am using the iwl drivers and wicd.

Well I did some more testing and loaded up netcfg and still get the same results so that rules out that part.  I also did some packet captures and I am getting a bunch of tcp retransmissions followed by tcp segment lost followed by a reset which in turn kills my rdp session (remote desktop protocol). I also went back several versions of the uucode driver and still get the same reults so I guess it seems to be a kernel issue.  Back to FC I go.  Damn shame...

Re: WIFI dies when transferring big files over the network

Seems as though my last set of updates over the past few days as fixed my issue.  Glad I held off on the rebuilds.  My issue has been fixed and rdp is rock solid again, no lag during ssh sessions, etc....

Maybe others are fixed as well?

I have ipw2100 and with networkmanager I got random disconnections from AP but with wicd it works fine.
