Routers with wireless can be affected by interference from other devices that radiate an RF signal.
My Netgear wireless router connection is mostly lost when my neighbor uses their 2.5 Ghz cordless phone.
Since the routers use the same band of frequencies as corless phones, the phone causes enough interference to cause the packets to become garbled and thus the connection drops.
Another router in the area could be on the same frequency (channel) as well.
Solution is to scan with the wireless device and see what channels are not in use by another router.
Choose that channel in the router and have your wireless device scan till it relocates your router's frequency and makes a connection.
If it is indeed a cordless phone causing the dropped connection issues, hopefully you moved off of the frequency it was using. Chances are, that is what's causing your problem because another router
is always on the air, while a cordless phone is only on air while someone is using it, which is randomly.
