DNS services just stops working on Home Bub 2

Hi

After running for a couple of days the home hub 2 simple stops responding to DNS requests.

My linux client has the router IP as DNS server in resolv.conf, which it gets from DHCP.  I can work around this by either:

a) define my own DBS servers, eg 8.8.8.8
b) reboot the Home Hub 2

but neither is a solution.

I see others have reported similar.  

While troubleshooting I noticed I had uPnP on, which I didn't want or need so I disabled.  I also disabled "Web Protect" as it was suggested might resolve the issue.  But the issue remains.

Ideas?

Use a Raspberry Pi as a DHCP server and DNS proxy.

Thanks for reply. Which I appreciate. I have 4xxPis already, in various locations. 

But this is a BT forum. I’m looking for how to get the BT smart hub 2 to work properly, not workaround.

Good luck with that.

The BT Hub seems to sufferfrom memory leak and needs frequent re-booting if worked too hard.

There comes a time when the pragmatic solution saves frustration.

If we now don't need to worry about DLM sticking its nose in because of being on full fibre, why not just plug it into a timer and reboot every night?

I presume BT personnel will respond eventually. 

In the list of workarounds is “change provider”.

Not on here they won't.

This is a customer-to-customer self-help forum.  The only BT employees are the moderators and they don't necessarily read all posts.

You'll need to phone customer services if you want BT personnel.

This is a customer to customer self help forum. The forum mods are not technical experts.

I fail to understand your reluctance to implement a very simple solution when you already have the wherewithal to do so.

Re: DNS services just stops working on Home Bub 2

Your lack of understanding isn’t my problem. You don’t know the ins and outs of my situation. 

I do appreciate the suggestion. But I have no desire to allocate a raspberry pi to dns/dhcp services, these are part of the product i am paying for.

 If it can’t be done more reliably with the BT hardware, I’ll probably just change provider. It’s not a threat, just stating the obvious. 

I’ll open a support request as suggested. 

A daily reboot workaround is also noted. I’d thought of that too, but am still hoping BT might actually fix the underlying issue. 

if everyone just works around problems and doesn’t pressure vendors to deliver better service, then they won’t. Obviously this forum is not the place for that pressure, but I thought it was worth asking. Seems a known issue. 

It’s sad but true, I’ve worked for a major telecommunications company and the priority of a bug is often measured by the count of open tickets against that bug. I was told once that every support call, where a support person has to speak to a customer, even for a few seconds, costs €60. That’s why they invest so much in AI tools to avoid person to person support calls.

So, in a nutshell, you're happy to apply one workaround (change supplier) but not another. Fair enough, your prerogative.
