I don't know about a new one...but I think it's a good idea to have a backup on hand, since the useful life is indeterminate.
I don't pay attention to specs, brand, etc. when it comes to routers...I just want one that works and I find that cheap ones do the job to my satisfaction.
A router for home use is not something that has to be agonized over, IMO
and I find that the ones in the $20-30 range give me no cause for complaint.
Just about all routers for home use will say "wireless" but they also accommodate ethernet cable.Examples
