Very poor unusable WiFi yesterday evening--attributed to overheating router?

[Perplexed1]

Hi.

From around 9-10pm yesterday evening our wifi was effectively unusable. This morning I used 'Chat' to get help from TalkTalk and was advised the problem was caused by overheating of the router and/or the OpenReach connection box, and that the problem was now resolved by action taken by TalkTalk person doing the Chat.

I haven't been aware of overheating being a problem before. The router had been streaming sport for an hour before the problem arose. I would like to know what steps the TalkTalk person took to resolve this issue remotely, and to know what steps I can take to prevent a reoccurrence.

Any ideas ?

Thanks

Hi @Perplexed1 

Do you still need help with this?

Hi Perplexed1

I'm sorry to hear this.

How long have you had this router?

Do you believe the router is over heating? Does it feel hot to touch?
