You may want to check the firmware on your access point and/or router. See if there is a new version on the vendor's web site and see what the bug fixes are in the upgrade. You may find that there was some problem that they finally fixed. I had a problem on my US Robotics router and access point where the wireless systems would crash and the whole thing would reboot, but it was finally fixed with a firmware upgrade. Another problem could be signal interference on the frequency you are using. You may try changing the WiFi channel you are using on the router. The frequency used by WiFi is unlicensed and used by numerous products such as cordless phones, wireless video cameras, and microwave ovens. Your current frequency may be flooded with other competing signals from your own residence and from your neighbors. You will probably have to reference the documentation of your 2.4GHz electronics to be sure of their frequency usage and to see if it can be adjusted. I have some X10 wireless cameras and I have them around the channel 1-4 WiFi frequencies and my WLAN on channel 11 so there is no chance of them interfering. As for microwave ovens, you probably don't have to worry about those unless you have a really old one that leaks GHz radiation, in which case REPLACE IT!!! :-) Mike Frequency references: http://hypertextbook.com/facts/1998/HowardCheung.shtml http://www.moonblinkwifi.com/2point4freq.cfm ____________________________________________________ Want to buy your Pack or Services from Mandriva?
