"Fix" for data corruption when using 2200BG Wirele

[darrenf]

Since installing the 8.1 drivers for my Intel 2200BG card I have been struggling with corrupted images and html, an occasional inability to acquire a DHCP lease and, most frustratingly, frequent dropped remote desktop/terminal server sessions that report an encryption error.

While trying to locate the v8.0 drivers (which did not exhibit the problem), I think I found the answer here:

http://support.intel.com/support/wirele ... rd1637.htm

Basically, Intel is blaming everyone else for not properly supporting some power saving standard for wireless called PSP. I find this unlikely unless they just added support for PSP in the 8.1 driver and were using a different power saving mode in 8.0.

Anyway, the solution is to disable power saving on the 2200BG all together (great news for laptop users, eh? ).

I have run without power saving mode for two hours and have not experienced one corrupted webpage. I've also been working in a RDP session in the background and it has stayed up the whole time. Given that errors were occuring on about one out of four webpages and that RDP sessions were not lasting more than a few seconds prior to the change, I take this as a sign that the "fix" has indeed worked.

BTW: I chose this over a return to the 8.0 driver because it had a well documented problem that would cause a BSOD under certain circumstances. This was happening to me once every couple of days.

If you try this fix, please share your results here.

Thanks!

Interesting, i've noticed many corrupted images on web pages lately as well. I've been assuming it was my router, not the card... Geeze....

According to Intel, it is!

For what it's worth, I had similar symptoms myself with the latest IBM driver (8.1.0.25). I'd get corrupted downloads, broken remote desktop sessions, broken streaming video, etc over the wireless adapter. Following the advice of another thread here, I pulled down the latest Intel generic driver (8.1.0.28 ) and manually applied that over the IBM packages (I ran the Intel executabable to install the driver, but others here suggested just doing the "Update Driver" thing in the Device Manager). Anyway, that seems to have taken care of the problem in my case. I'll probably just run like this until IBM releases an 8.1.0.28+ driver package.

Just FYI, I was using Access Connections v3.10 and have since upgraded to v3.40. Both have seemed to work fine with the newer driver.

what was the problem with the 8.0 driver?

[puco]

AFAIK problem with 8.0 was occasional BSOD when using WPA.

i dunno what the problem was, but the new driver worked for me-- no change in overall functionallity other than it working (i use xp wifi manager)

[darrenf]

I didn't know that the BSODs were WPA related, but I do run WPA so that fits.

FWIW, the driver that I'm running (that exhibited the corruption) was ganked from the IBM website IIRC and is an Intel driver v8.1.0.26 dated 6/24/04. The same problem existed in the Intel 8.1 beta drivers. I'll try the 8.1.0.28 driver.

Turning off power savings did not make a noticable impact on my power usage (hard to quantify, but power use seems same as before the change) and responsiveness is much better. What are others experiencing?

Looks like some people are using the generic 2200bg drivers and it seems to fix the corruption... Gonna try it right now

I just returned home from being out of town and I ran into corruption again. I should have checked my power settings, but I guessed that they had been restored when I restarted the machine so I just went ahead and put in the generic drivers and activated power saving. I have *not* made a change to my base station yet.

No problems so far after about 4 hours of use, so changing the drivers looks to be the best way to go.

FYI: I also installed the wireless Intel PRO monitor thingie because I like having a signal strength indicator in the system tray (I don't use Access Connections any more). I do not let it manage my connections, though. I am using Windows XP Wireless Zero Configuration to manage connections.

Thanks! Intel drivers solved my corrupted html and images with 2200bg on my x40!
