We have been happy FIOS subscribers for years - internet, phone and TV. We have a reasonably large number of devices - 3 DVRs and a STB (coax), a thermostat device, a printer and an Windows laptop connected by ethernet, 2 Windows laptops, 1 Macbook Pro, 3 iPads, 3 iPhones, Apple TV, and an XBOX connected wirelessly to the Actiontec MI424WR Rev D.
Recently, my son has been complaining about slow internet access, and after a fair amount of research, I bit the bullet and ordered (and paid for) a new Actiontec MI424wr Rev I (GEN 3) to provide wireless N and gigabit connectivity. During the first month, it worked great (lost connectivity once and I restarted the router) but most of the time, my husband and son were away, so it was only me. Since they have been home (less than a week), I have needed to restart the router 8 times, each time sooner than the time before. While the Mac and XBOX and wired devices seem to continue to work fine, the Windows laptops lose connectivity. I can watch the green bars go from 5 to 4, then yellow exclamation mark and no internet, then connected again every 30 seconds forever (as far as I know) - router log says PC is making DHCP requests over and over, PC log says DNS is not responding. Router is on the newest firmware (40.19.22) Lights on router continue to flash. Powering the router off fixes it, but only briefly (went 24 hours the first time, now down to about an hour)
Finally fed up, I put the old router back, and we have not hae a problem since then (18 hours so far) but we've lost the faster wireless.
Any suggestions on what to check, or how to do further troubleshooting? The router was a final sale, so I guess I can ask to have it replaced under warranty, but I can't just return it for money back. There do seem to be lots of other people who want one, but maybe they wouldn't after trying it...
