I apologise if this is the wrong thread im not so good with forums but I recently cleaned some dust off of my Router and it kicked me off of it saying 'Your isps DHCP isnt functional' and repeats the problem constantly. this router is plugged into another router downstairs currently and for 8 months has let me use it just fine until the other day when I cleaned it. I factory reset it and it works just fine when I connect to either the 2.4G or 5G. and then maybe a day or so later it repeats the issue. I dont want to mess up my router so I am asking for help on how to solve this. it says the network cables unplugged then disconnected then 'Your isps DHCP is not functional' and repeats this. please help and thank you.
