Hi all Apologies if this is an FAQ. I have searched around on this site, but cannot find an answer to this specific question. My WRT54GXv2 router (was running 08 firmware, but now upgraded to 10), performs very erratically. The speed often drops to 1.0Mbps, and I also have a problem that the network completely disappears. That is, the router just seems to stop advertising its SSID,. my laptop loses its connection and cannot reconnect (becuase it can't see the network). When this has happened, I use NetStumbler (on the same laptop) to look for networks and it simply does not appear in the list. The intruiging thing is the Wireless light on the router is still on. The only way to fix it (other than power-cycling) is to access the router from my desktop and change something (e.g. channel), and then it comes back to life. Other networks in my area are on channels 11 and 6. I am using channel 1, but I have tried other channels (2 and 5) to no avail. Could this problem (i.e. losing SSID) simply be due to wireless interference? Or is there a problem with my router hardware? What about the signal strength problem? Is that just interference? Should I continue experimenting with channels or are there other settings I can change that may help? I am good at network stuff, but pretty new to wireless. Oh, by the way, mine is setup with WPA2 security if that helps... Thanks for your help!! Ian.
