BT Homehub 5 keeps losing wired connection

[Froofpin]

Hi,

Recently my HH5 has been losing internet connection every few hours, although the blue light remains on. Within a few minutes I get reconnected on my PC which is connected via ethernet. Wireless devices also lose connection during these moments. The loss of connection seems to be exacerbated when I join any online game server. For example the connection will be fine while browsing on chrome and then when I join any game server (game: Battlefield 3) I will immediately be disconnected within seconds of entering the game, and the warning symbol will appear on network status in system tray. 

Below is the log of when I got disconnected (by my clock the game crashed at ~17:11, having attempted to join the game ~2 min beforehand)

17:15:48, 18 Jul.	( 2669.810000) Wire Lan Port 4 up

~17:16 was when the connection began working again. Could this be a firewall issue?

Any advice help on this issue would be greatly appreciated.

Kind regards

Hi @Froofpin and welcome.

I'm sorry you've having problems. Does anything else happen when the connection drops? For testing purposes are you able to try uploading a large file e.g. 5GB to an external cloud service to see whether it triggers broadband drops.  

Cheers

David

I am unwilling to do that because with the internet speeds I get that would take about 10 hours.

Had another disconnect today:

Start an upload and then see if anything happens! You don't have to commit to the full 5GB.
