Hi all, I'm running ndiswrapper for a Netgear WG111. The box is a MSI board with VIA chipset, an athlon-xp CPU at 1500Mhz. Running a kernel 2.6.11.11. Most of the time it works correctly, but suddenly, if I try to open web pages it looses the connection to the AP. Connection speed drops to 2 Mbps and the acces point fields is filled with random numbers. KwifiManager reports that signal did not had any loss nor any noise. After a few seconds the reported signal start to go up and down regularly as on startup. I have to disconnect the device from the USB port and it restarts. Sometimes the connection stays up, sometimes it drops after a few seconds. I tried to enable debug but no useful information. Any hint to help tracing what's happening?

I have this kind of problem with this dongle (WG111v2 I think) but I don't use it in managed mode (only in ad-hoc mode for the moment). My previous message : > I use the last ndiswrapper-1.2 with my USB dongle Netgear WG111v2. All my small > network is in Ad-hoc mode with 128-bits WEP encryption. > My other wifi cards are based on RT2500 (and work fine). > > In fact, in my local network (IP 192.168.1.x), for HTTP, FTP or SSH, > ndiswrapper-1.2 with WG111v2 works fine.

What is the chipset in wg111? As stated in wiki, see debug trace and/or system log to find out what causes connection drops. -- Giri |

If you refer to ndiswrapper debug logs it is a big problem. I tried a couple of times but I got a 100 Mb logs. If that is only way I'll give another try.

I believe this is prism based card. I do have this card and I don't remember having similar issues, although I haven't done extensive testing. Please file a bug report about this. I heard that open source driver at prism54.org works with this chipset. You may want to try that, too. -- Giri |
