Time to get technical

[Banjacked]

Ok, time for some thinking. Recently, after a replacement Siligence modem/router, the same issues of the modem/router doing random shutdowns due to "suspected power cycle" have started. The worst one came shortly after a reset of the modem due to wifi speeds going to below WiFi4 level, there's no specific time, no specific reason, it just drops at random at any time of the day or night. 

Putting a hand on the modem and you feel it's rather warm despite it being on the wall in the open, not enclosed, good air circulation.

This has me suspecting it may be "overheating" from time to time, irrespective of how intensive the use is, and I don't feel like pulling the power every night to let things rest.

So the question is simple. If I put the Siligence into "bridge mode", disabling wireless and everything except the WAN and one LAN port, will that help with temperatures and possibly the random shutdowns, while putting everything else through a new WiFi 6 router. I'm looking at solutions because this replacement started the same problems as the original one within weeks of installation, and they are increasing in frequency. Orange won't give me a newer model of modem, not even with the upgrade to Zen Fibre, and another SIligence will only end up doing the same again.

So, could this help solve what seems to be an inherent problem with the modem as it heats up if most of its hardware is disabled in bridge mode?

Well, to finalise this thread, the engineer has been and it was proven that the Siligence was faulty. He tried to do a speedtest on wifi and the modem decided to reboot itself with no warning there and then, the perfect time for the Siligence to throw a tantrum! No questions from that point onwards and the LiveBox was fitted. Now, after resetting everything to the new network, WiFi 5 speeds are clearing 450Mbps, effectively doubled. 

A very happy camper, and one that is happily sticking to Orange no matter what because the service is second to none.

Happy it turned out like this.

Well, as is typical, I ordered the Xiaomi and then got a message from Orange. A quick chat, and an engineer comes out tomorrow with a LiveBox, even though I'm on Zen, because seemingly the up and downstream readings aren't what they should be. Also I should be getting a better WiFi 5 speed than I do, especially within 4m of the router after optimising channels. Indications are that the Siligence is faulty, and heat may be an issue even though it is in shade and clear of all forms of heat with a decent airflow. Ok, I have a spare router that I can mesh if I want to!

That's good news.  I take it your ordered the Xiaomi on-line.  You can send it back if you don't need it when the LiveBox is installed.
