Hi,

Anyone using the Huawei Soyealink B535-333 having this problem?

Speed is great but the modem would quite frequently after a while freeze for about 10-20 seconds (your internet connection stops working but remain connected to the wifi, also the router page becomes inaccessible), before suddenly restarting on its own (all lights go out and turning back on by itself).

At first I thought it was overheating but putting a fan doesn't work. Plus, there can be long stretches of high speed when I download something off Steam through my PC, sometimes for hours, but the freeze and reboot doesn't happen.

Replicating the problem can be a bit hard but I notice this almost always happens when I'm watching FB reels or IG videos on the phone connected to the router. Sometimes youtube videos can also trigger this, but it happens less often.

I've cycled through three B535 modems - two from the same seller on Shopee (replacement) and one I bought through FB marketplace. All exhibit this problem.

Any ideas? Help please as I am at my wit's end.

TIA
