I have a Z100G at work and the kid taking the trash out dropped a 20 gallon metal trash can on the WAN line smashing and shorting it. I replaced the end above the damage. Now I can not get a connection. I tried another router and it works. I guess my question is, if the WAN line shorts, can it ruin the router? Can these be sent in for repair and if so, how much does it cost? If I buy a new one, can I transfer the remaining time on my subscription to the new one? Sorry for all the questions.

I'd try another new end on the cable or a whole new cable if possible first. Or test the cable if you have the tools. Or try the router in another location. Might save you ordering a new router.
