I don't know that router since I typically run linksys or dlink routers with tomato firmware ... but ..
When you say you set the router's DHCP server to 192.168.0.1 ... are you referring to your router's LAN IP address? Which means, that in order to get to your router's control panel, you would access
http://192.168.0.1 (or https depending on your settings).
Yes.
I think you also mentioned that you were only able to connect to one other wireless network (and it was using WEP).
This may be a bit tedious, and it may replicate some of the troubleshooting you've tried already .... but these are the steps I would troubleshoot in:
1) Hardware reset both router and phone.
Done.
2) Ensure there are no wireless profiles listed on the phone (there shouldn't be .. but worth checking anyway).
Done. No effect.
3) Do the bare minimum to get an Open wireless connection functional on your router
4) Connect a computer wirelessly to the router. -- if it works, go to next step
5) Connect the phone to the router. -- if it works, go to next step
Only way to get the phone to connect without static IP.
5) Hardware reset the phone -- double check the wireless profile
Done
6) Set the router to WEP
7) Connect the computer to it -- if it works, go to next step
8) See if the phone will connect to it -- if it works, go to next step
9) Hardware reset the phone -- double check the wireless profile
10) Set router to WPA2
11) Connect computer -- if it works, go to next step
12) Connect phone -- if it works ... have a shot, you deserve it. If not, find the nearest hardware store, procure a sledge hammer and strike the phone several times until you can't feel your arms.
It doesn't work. Sledgehammer option strongly considered. Verizon does not recommend this option to maintain warranty service.
The reason I said check your wireless profiles is because I feel like mine showed up even when doing a full wipe of my ROMS. But the number of times that I've upgraded in place vs wiped the phone completely may have blurred my memory.
