I use a Arris dual band modem/router along with a TP range extender in my single level home. I have a 100Mbps Cox service
For months I have had inconsistent connections. I blamed the extender and have since replaced it with no improvement. Then I blamed my laptop, replaced it and saw no improvement.
Here are the symptoms
- 5Mhz band works consistently and at high speed
- 2.4Mhz produces 75% the speed of the 5Mhz band but is inconsistent
-- Speed will abruptly drop to 5Mbps
-- It will stop working totally
-- If it drops to very slow, it will continue to work one some devices but not others.
-- When it drops it will still show as an available band but will be "connected, no internet"
This is a maddening situation as my Windows 10 Machines will not connect to the 5GHz bands at all. Macs always do.
