I have a metal roof on my house so it raises He?? with the wireless signal in the house. So back in October I purchased a range Extender for in the house. It worked fine for a while but now I have been having issues with it. Poor Call quality, dropped calls, and so on. Verizon of course blamed it on my Internet provider. My service is bonded dsl 25 Meg down 2up with Frontier. They now given me the latest Router/Modem on the market. checked my lines and quality of service at the main office twice. Now for phone's I have a Note 3 a S/4 Mini and a Nokia 928. The one with the most issues seems to be the mini. Though they all seem to have issues. So to me it has to be the Extender. I have opened two tickets to no avail. Should I be pushing for a replacement do you think? I consider myself pretty tech savy but I must admit the technology behind this device I don't completely understand? The unit cost over $200.00 so I guess my expectations are pretty high. So what would you all do? You folks out there with this device know any tricks I might try??? Help :banghead: ?
