Archer C5400X w/ latest firmware, drops wi-fi connectivity to internet all the time.
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Recently upgraded the modem firmware to version 1.1.2 Build 20191223 rel.73956(5553) using the local upgrade method (not via gui) to get my download speeds to 600 mbps (max for my cable sub).
Since then, none of my wi-fi devices will stay connected to the internet. Connectivity comes and goes randomly, one commonality is that I cannot sustain a connection through a wifi device. All my wired connections are fine so I know it is still connected to my cable modem and it still has internet connectivity.
I've tried to connect across all 3 wi-fi networks (2.4ghz, both 5ghz). isolated the number of devices connected to 1, turned off wi-fi radios to see if it was a interference issue, changed from auto channel selection to specific channels, turned on MU-MIMO, turned it back off.
Nothing works.
With the stock firmware, I couldn't get full speed from my cable connection, but the wifi connectivity was not an issue. Something happened when I upgraded.
I'd like some help please.
In the meantime, i'm going to try and apply the 1.1.2 Build 20191223 rel.73956(5553) firmware again and see if that does anything...

Router is back to the same old issues. Wired or wireless, but wireless does have issues more often. Tried every setting I could think of and running the router with basic settings. I also tried each version of the firmware on the website. It seems I am just going to have to eat the $300 I paid for this router and buy a different one.

So I got on again tonight with support chat and lo and behold Ronald told me to try a combination of channel width and channel that we previoiusly had not tried like he knew exactly what to do and boom! My 5Ghz 1 now connected fully no problem so now I am back to a full Tri Band Router on the newly received RMA replacement. Thanks Ronald!
So if you are having the issue where one of your 5Ghz bands let's you connect to the wifi but then says no internet connection try this:
Channel Width: 40 Mhz
Channel: 36
