Ok! So... this is my situation. 

I bought this router in April 2022. It came. I hooked up to my network. And worked flawless. 

About 2 weeks ago i went into the router's menu to see something. I was just courious! 

When i went in i have noticed that somewhere in the corner was a red dot that warned me about 

a new version for firmware. It was there likei show you in the image. I said... ok. I clicked and

it asked me if i want to upgrade. I clicked yes and let the good boy to do his job. Baaaad mistake i did.

After that. Nothing worked proprely. I want to mention that the router it has been in the same possintion

for the  past 2 years. I have my computer hooked to it on a wire. NOT wireless. After this upgrade

the internet is connectig and after a few minutes is disconecting, then reconnecting, stay like that for a few minutes

than again ... it is a nightmare to use the internet. First i thought that problem was the internet provider itself. 

When i connected my computer directly from my spliter (i don;t know if i use the correct term) that my internet 

provider gave us the iternet is working perfectly. If i connect again the router... is the same thing as before. Connect, stay, 

disconnect, connect...etc. If i would be the only one usig the net i wouldn't need the router. But unforunetaly 

i need it. Because there are others using the internet.  And yes i have tried resetting it. Still doesn't work. I've tried 

reseting it to factory settings. Nope. Same thing, Please can anyone have a sugestion? Solution? Or i have to buy a new one?
