Home Hub 5 Firewall bug causing dropped DSL connections?

We've had infinity 2 since the start of December (2013) and have had nothing but problems with it.  It frequently (5x a day atm) drops the connection, sometimes it fails to re-obtain the connection so does a full restart.

 

We had an engineer round who couldn't find anything wrong with our line, swapped us to another cable pair, but after a week of "stabilisation", the problems were still there.  We had a "new" home hub, which had been left using a test bench WiFi Id, so I suspect it was another faulty return they've given us.  It has been better - possibly 1/2 the number of disconnects, but still having problems.  We had another engineer round, who replaced the backplate on the BT socket with a new one, with better rated capacitor for filtering.  A few days later, not much better.

 

What I have noticed from the logs, is that the loss of connection frequently happens a few minutes (normally 2, sometimes 10) after the hub has blocked bogus (normally Chinese) remote admin attempts.  Is there another attempt they're making that kills it, or is there a potential bug in the firewall that trips the reset?

 

08:34:03, 01 Feb.IN: BLOCK [16] Remote administration (TCP 61.160.195.250:6000->86.134.x.x:22 on ppp3)
08:05:09, 01 Feb.IN: BLOCK [16] Remote administration (TCP 211.75.112.37:61650->86.134.x.x:80 on ppp3)

 

It quite often drops the connection just after I have connected using my Android phone (which has no problems with any other device).

 

The log (before a reset) also includes bogus entries such as:

09:08:18, 01 Feb.BLOCKED 2 more packets (because of Advanced Filter Rule)
09:08:17, 01 Feb.OUT: BLOCK [44] Advanced Filter Rule (fw/policy/0/chain/fw_ath12_out/rule/0: UDP 0.0.0.0:68->255.255.255.255:67 on ath12)

 

Again, the firewall kicking in, just before a reset?  Coincidence?

 

Line stats:

3. Firmware version:Software version 4.7.5.1.83.8.173.1.6 (Type A) Last updated 15/01/14
4. Board version:BT Hub 5A
5. VDSL uptime:0 days, 00:28:57
6. Data rate:6446 / 52409
7. Maximum data rate:6616 / 52721
8. Noise margin:6.2 / 6.1
9. Line attenuation:0.0 / 23.2
10. Signal attenuation:0.0 / 21.3

 

I'll have to give the line a few more days after last week's engineer visit before they'll listen to me again, but I'm considering cancelling my contract on the grounds they're unable to provide me with a stable broadband connection - despite the same line running standard ADSL perfectly well for 4 years 😞

 

Oh, the HH5 also makes a quiet whining and ticking noise if you stick your ear up to it - is this normal?

This happens at least once per day and still no one has explained why.

Did the other two make a quiet whining and ticking noise?

No but then they weren't faulty even though they were diagnosed as being faulty by the Indian Call Centre.

 

Maybe you can tell me what is causing my issue though?

Have you got an OR modem?

Yes and it didn't suffer the same issues. This is only an issue with the HH5.

From my own experience of having had three HH5's diagnosed as faulty and not one of them was.

You still have the same fault but not with the OR modem. Sounds like the HH5's are faulty 😉
