We've had a MI424WR actiontec router for about 3 years now with the 50/50 fios plan. Recently we had a snow storm that caused our power to go out for a few days and damaged the Fios lines into our house.
Verizon came out and repaired the lines. Since power has been restored, we're getting weird wifi behavior. Speedtests show that the download speed average is usually between 3-8 mb/s, while upload is consistently 35-40. Prior to the power outage, with the same number of devices connected and same physical location of the router, the download speeds were always 30+ mb/s pretty much everywhere in our small house.
I spent an hour on the phone with support. They had me change the channels, hard reset it, unplug it, etc, all to no avail. The speeds if I plug my laptop in to the router via ethernet are good, 60+ mb/s up/down. Basically, the only variable seems to have been the storm and power outage which is now causing the wifi download speed to suffer.
Could the router itself have been damaged in some way, or is it possibly just failing due to age? The thing that throws me is the fluctuating download speeds when testing it while the upload is consistently fast.
Any other steps to try? Of course, support just wanted to push me into a newer router purchase, but unless I'm sure it's an issue with the router I don't really want to go that route.
