BT Homehub 5 keeps losing wired connection

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
17:15:45, 18 Jul.( 2666.810000) Device disconnected: Hostname: Unknown-​bc-​5f-​f4-​67-​6e-​f0 IP: 192.168.1.23 MAC: bc:5f:f4:67:6e:f0

~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

Re: BT Homehub 5 keeps losing wired connection

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

Re: BT Homehub 5 keeps losing wired connection

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

Had another disconnect today:

15:12:25, 21 Jul. (254465.410000) DSL noise margin: 13.50 dB upstream, 6.00 dB downstream
15:12:25, 21 Jul. (254464.590000) DSL line rate: 448 Kbps upstream, 5237 Kbps downstream
15:11:57, 21 Jul. (254437.390000) DSL is down after 4238 minutes uptime
15:11:57, 21 Jul. (254437.390000) ETHoA is down after 4238 minutes uptime
15:11:57, 21 Jul. (254436.840000) PPPoA is down after 4236 minutes uptime [Waiting for Underlying Connection (WAN DSL -​ Up)]
15:11:51, 21 Jul. (254430.710000) PPP LCP Send Termination Request [User request]



and these seem to be the disconnects for the previous days, they are much closer together:



00:49:28, 18 Jul. (368410.530000) DSL noise margin: 15.00 dB upstream, 6.00 dB downstream

00:46:29, 18 Jul. (368232.010000) ETHoA is down after 8 minutes uptime

16:20:53, 18 Jul. ( 1254.100000) DSL noise margin: 12.50 dB upstream, 6.00 dB downstream
16:20:52, 18 Jul. ( 1253.410000) DSL line rate: 444 Kbps upstream, 351 Kbps downstream
