AT&T signal strength on reboot

Post by NETexas » Thu Aug 26, 2021 5:19 pm

I use a Netgear 1100 for home WiFi. Using AT&T. On reboot the signal strength is three to four bars then after a minute it falls to one or two bars. Why does this happen? Thanks for your input.

Welcome to the forum.

You're likely seeing a band change. If it swaps from a lower frequency band, like 12, to a higher frequency band, like 2 or 4, then that could definitely make the reported signal level change. Higher frequency doesnt travel as far or penetrate as well as lower frequency signals.

That or its changing towers.

The router can force the modem to query area towers for different stats and choose a band to anchor to based on their decided algorithms.
