WRT160Nv3 Wireless connection usually requires reset

Question

Hello all, thanks for such a wealth of useful info in other threads, but none deal with my problem.
Generally, I've been very pleased with this router, it worked well for a week or two, but now I can't connect my laptop without resetting it, and I'm back to using a wire which is annoying having bought a fast wireless router. I have had this router for under a month. I do not want to use network magic.
So far I've tried: 
Using just my modem - no problem;
using wired connections - no problem
my old router - fine for wires
pointing my browser at 192.168.1.1 - I don't know username or password as I've never used it before
restarting both cable modem and wrt160n - no effect; sometimes works wirelessly for a while then breaks.
Please let me know if you can help. I'm going to return this router in the next week if I can't get this sorted.
Thanks again,
 -Sam

I would suggest you to adjust the wireless settings on the router...The router's default password is "admin" in lower case.However as you do not remember the router's password,you have to reset the router for 30 seconds,power cycle the router and reconfigure the router from scratch.
On the setup page,Under the Wireless tab,Change the SSID to some unique name,Change the Channel Width to 20MHz only and Channel to 11 and click on save settings...Under the Advanced Wireless Settings
Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2307 >>Click on "Save Settings"... Under the Security tab..Uncheck "Filter Anonymous Internet Requests" and click on save settings..
Power cycle the router and check..
