Ive been living at a relatives house for a while and ive been using the wifi from their router not too far away, maybe like 10-20 feet away through a couple walls, so signal isnt amazing, but not horrible usually, but this is just temporary. Anyways, my cousin had configured their router for them, i believe it is a Cisco router, not sure what model though, their ISP is Time Warner Cable. It seems like everyday i get disconnected from the wifi signal whether i am on my iPod Touch or Xbox 360. My hardwired pc is fine though, just slow internet, but that is to be expected i guess (router, isp speed, devices connected and using bandwidth, etc.) Anyways, could this be because of DHCP Lease renewing? At my house before, i had AT&T U-Verse and the technician set up everything, i never messed with the gateway settings or anything they gave me, i had no need to... It was a default ATT Uverse gateway (modem/router/switch combo). I dont know much about DHCP renewal, but i believe the tech from ATT set the gateway to never expire or renew, and i believe my cousin set up this router to renew DHCP leases every whenever. Could this be the reason i get disconnected on WiFi devices every so often? I have problems with it everyday here, as where before with my old untouched-by-me internet was totally fine, so this leads to this suspicion.

Please help. Thanks!

It is pretty easy to test just go into your PC and put in a static IP address with all the proper gateways and dns etc. If you know the excluded range in the DHCP pool that would be best but in general DHCP gives out addresses from the bottom. If there are not a lot of machines using the network it will never hit the top ips. So you could take a IP from the top of the subnet and it would likely never be given out by the DHCP server......smart DHCP servers always try to ping the IP before they give it out just in case someone is using it.
