Need to reboot Hub 3 router daily as loses connection

[AElmariesh]

Please help! This is driving me crazy... Have a new BT Router (Business Hub 3) connected via a Infinity 2 80/20 Fibre connection. Nearly every day, the internet goes down (the lights on the router all stay blue and connected), but running a windows network diagnostic always shows the following error message "The DNS server is not responding". There is nothing on the router event logs. Restarting the router always connects again until it shuts down the next day... this has been happening for the last 2 weeks and I cannot run an internet business with servers going offline every day. I rang the support line, but apparently this is a known fault with no apparent resolution, although a new router is being shipped to me... Does anyone know what is going on? Desparate for information... Regards and thanks Anis

ve the same problem, but am regrading to Infinity 2 tomorrow.  The problem appeared around the 9 or 10 May, and a BT bod told me that a firmware upgrade went out around that time and lots of people had been reporting the same issue. I went away to check the firmware version, which was as he quoted, but when I spoke to someone else they basically fobbed me off and logged a line fault with Openreach!

We were "up" from Sunday until this evening, so I thought the issue had passed on its own, but no - it's back!

Will be speaking to BTB again tomorrow to try and get them to replace the Hub 3 - we have only been on the service since the end of April, so I think a swap is the least they can do!!

Hi Turv Thanks for reply. Will a new BT 3 router be sufficient? Wont it have the same problem? In the meantime I've swapped back to my older 2701HGV-C router - hopefully the problem was router/formware specific as you say and at least my internet wont go down in the middle of the day and stop all my servers from working. Thanks

Hi. "The DNS server is not responding". Looks like a DNS issue right here. Try assigning a static one on your notebook. say 4.2.2.2 or 8.8.8.8, those are opensource DNS servers on the internet.

Is it a Hub issue or is it the modem?   Have you proved conclusively that the hub is at fault?

[Turv]

use Google DNS on all our PCs and laptops, and the problem persists.

A BT operative told me it was probably due to a firmware upgrade to 4.7.5.1.83.8.82.1.1 (type A) dated 9/5 as they had quite a few calls with the same problem since it went out.  The issue leaves the Hub unresponsive (cannot even access the 192.168.1.254 config pages) and the reset button doesn't work.  only a power cycle will bring things back to normal, until it goes down again.  My money is definitely on the Hub!

[Turv]

oh, forgot to add - the modem does not require reset  - all lights seem normal, and once the Hub is power cycled, all is well again!

Problem peristed all throughout weekend... BR was supposed to send out a replacement hub last week but nothing has arrived.... Turv - identical symptons... Still no fix then?

I am SCREAMING at the walls in sheer frustration at BT!! HOW UTTERLY RUBBISH!!!! Receive a voicemail call saying closing my issue as they cant get through to me Say if i want to call them back I can (giving me: 0800 678 1107) as the number to call. Keep getting through to some guy saying he is BT Wholesale and he cant help me! I AM "THIS" () close to pulling the plug on BT - UNF*"(&£*^%*$KING BELIEVABLE...

Is this issue now resolved for you?  If so what sorted it? We have had infinity installed recently and are having to do a factory reset every 24/25 hours.  BT seemed to have no idea why.
