No internet on devices for a few minutes intermittently
I have a separate modem and router setup. Docics 3.0 modem and a TPlink archer c9 router (loving it for the past 3 years).
The wireless devices connected to tplink router looses out internet frequently. Then, when I switch the network from 5g to 2.4g on the laptop/cellphone internet works fine again.
Same issues happens on 2.4g as well, i would have to change back to 5g and internet works again.
Or i can also toggle wifi on/off on my client device and i get the internet back.
The wifi connection to device is strong and stable, just the internet does not come through.
This happens on all the devices connected to my router.
This issue does not happen when i am on voip call, kind of a sustained connection, i was having a 30-minute conference on MS.Teams on my laptop and the internet connection did not dropout. But when i was trying to browse web pages right after the call, there was no internet for couple of times in the past 5 mins.
This has been happening for the past couple of days, i checked with my ISP and they said there are no issues at their end. I also checked with my neighbours having the same ISP and they have not been having any internet issues.
any help on this?
