Has been working perfect with no issue since I bought it 3 years ago. I now switch to Verizon for their promotion plan so the device no longer needed. Retail price $199 and market price for pre-owned is around $90-$100. Now sell at $60. Cash only please.

The modem comes with AC adaptor and a internet cable. It does not have the router function, for which you would need your own, or you can check out my other ad on selling the NETGEAR router as well (they pair each other for last 3 years' service so in perfect working condition)
