Hey there James, thanks for supplying me with a note for my current business systems class about how important something small can be. In week 3 we do some very lively discussions about why to have a "spare" or redundant hardware.

If it were me, I would by a second router immediately and depending on how badly the business needs the router, possibly even two and send this one back for repairs.
I would use one, keep one connected, but turned off until the 1st one has an issue.
I would not use the repaired one again unless the spare went down and only as a last resort. I do this at home and since the school work is pretty important I do not want to have no communications.
