Last June I was offline for a month while Verizon screwed around with the wires in my area. Spent alot of time getting the go-around with their phone support. They kept insisting it was my router...even after I took the laptop and their modem outside and plugged in direct. After weeks of BS, I finally found a tech who had a clue, who took the 3 hours needed to go through every possible router setting to find a fix. Mind you, each insistance that it was my router came with an offer to sell me a new one....
That router's been running rock fn solid for a year now....the one their said was fried last year.
Couple things you could try:
- Reinstall or update the driver for the wireless on the laptop.
- Delete then Create a new connection.
Bout all I can think of before coffee.
