5x00 General discussions / Network Problem

No knowledge of your particular card. From what you say, it sounds like you have a sporadic connection to your access point (AP). If kismet is working, chances are the problem lies with your AP's Internet connection, or interference with other APs nearby. Some general suggestions:
- If your Access Point is using channel 6 (the usual default), then it's likely to be on the same channel as nearby APs.
- Have you used this AP successfully with other wireless devices?
- (Install one of the console/terminal apps if you need to)
- From the console, type Code: [Select]
ifconfig wlan0You should get something vaguely similar to the following:Code: [Select]wlan0 Link encap:Ethernet HWaddr 00:0B:CD:A6:07:E3Look at inet addr, RX packets (receive), and TX packets (transmit). If the IP address and TX bytes aren't reasonable, your card isn't connecting to the AP, and you need to dig further. If TX packets is positive, but RX packets is 0, you're trying to connect to the AP, but it isn't responding (for whatever reason).

ping [your router's *internal (LAN)* IP Address (default is often 192.168.1.1)]If you can't ping your router, they're not talking. - If you can ping your router, then from the console, try Code: [Select]
ping yahoo.comIf it fails, your AP most likely isn't connected to the Internet at that point in time, or you're having DNS problems (most likely your ISP's DNS servers are flakey, or some other problem). - WiFi is plagued by a myriad of problems, including flakey equipment (APs and network adapters, as well as interference).
