PN Hub 2 reliability

davidj66 — Sun, 29 Mar 2026 14:12:13 GMT

I had the basic (up to 74mb) full fibre installed last May. Connection has been fine on all my devices ,either via wifi or powerline adaptors until this weekend. Now I'm getting disconnections/buffering on both sets of devices regularly - so much so that this afternoon's rugby on TNT Sports is totally unwatchable.

I've rebooted the router, and powered down the ONT changed the ethernet cables between the ONT and router and between router and the "home" powerline module but the problem is getting worse.

I've installed the Thinkbroadband quality monitor which looks awful to my eyes but I've no experience of using it !

Is there some way I can see from the Hub2 stats whether the issue is a failing outer or an external fibre issue?

@davidj66 Can you attach 1) The Hub event log and 2) a TBB graph showing you connection?

Thanks for reply. I've attached both ,I think !https://www.thinkbroadband.com/broadband/monitoring/quality/share/83587eeb56df49b60763f9278587a7c5e2352326-29-03-2026

I dont like the fact that whatever device has IP 192.168.1.107 keeps adding a port forward using uPnP !

what's that device ?

@davidj66 Your BQM looks pretty awful.

I'll look at the log when I get chance later, but as @MisterW is already on the job...

@davidj66

Have you any idea which device has the IP Address of 192.168.1.107? Could it be a gaming console?

23:05:08, 28 Mar. DHCP device Disconnected: 192.168.1.107, c4:2a:fe:13:33:25, unknown

06:31:14, 29 Mar. DHCP device Connected: 192.168.1.107, c4:2a:fe:13:33:25, unknown

192.168.1.107 is connected the eth0 - LAN1

Looking at the BQM between 23:05 and 06:30 this is when the connection had no latency.

I also note the 5GHz band is turned off?.

@MisterW ; appears to be a TV android box normally connected via powerline but ......107 appears to be it's wireless IP! Used to use it for TNT Sports but not now needed. I've disconnected it from power and powerline adaptor !

Re: PN Hub 2 reliability

@Dan_the_Van - power to the TV and attached devices is switched off between 23:00 and 06:30 - so the Android box would be off. Now permanently unplugged.

Not using 5GHz band because some of our older wireless devices didn't like dual band and can't give 2.4/5 bands different names - worked fine with older Hub One.

In that case, my guess would be that one of those devices is uploading a significant amount of data when on during the day.

Did you know you could still use the Hub 1 if its more convenient ? It will work with Full fibre BUT has an upstream limitation of 30Mb. However that's not a problem on your 74Mb FF product since the upstream is only 20Mb anyway!

Just connect the ONT to the WAN port and it should auto detect...

NB The BQM wont work though as the Hub 1 cant be configured to respond to WAN pings.

@MisterW I would venture to suggest it isn't a guess, more a certainty, and is the sole cause.

Re: PN Hub 2 reliability

Dan_the_Van — Sun, 29 Mar 2026 16:25:03 GMT

@davidj66

Curious to know, what powerline adapters are you using, did one include a wireless access point?

Edit: BQM looks better now

Re: PN Hub 2 reliability

davidj66 — Sun, 29 Mar 2026 16:20:52 GMT

Thanks for your very helpful suggestions both.

@Dan_the_Van - if disconnecting the Android box hasn't worked I'll try the Hub One.

Will monitor the connection for the next 24 hours but the TQM graph is already looking much better.

Thanks again for all help. For completeness, removing the Android box from the local network has solved the issues. Not sure which software package on the box was d/ling so much data and why.

.I had recently installed the Opera browser because Chrome was running very slowly on the box and I'd also installed HBO Max app ready for when TNT Sports moved across from Discovery+

I don't use wireless extenders - the TP-Link powerline adaptors are 200Mb pass thru .

Re: PN Hub 2 reliability

MisterW — Mon, 30 Mar 2026 13:56:46 GMT

They might CLAIM to be 200Mb but they almost certainly arent!

Your event log shows LAN port 1 connected at only 100Mb. My guess would be that the powerline extenders only have 100Mb ports.

In your case on FF74 it probably doesnt matter, but if you ever upgrade to a faster speed , anything connected via the powerlines will be limited to 100Mb

Can uPnP be turned off on the Hub2 as Port 34457 is well known for questionable traffic ?

Re: PN Hub 2 reliability

@MisterW , thanks for pointing out speed limits! I actually have older AV200 POWERLINE adaptors up to 200 Mbps but a few years later I added 2 *AV600 unts that I assumed would be up to 600 Mbps - but no, looking the manual up online ,those are only up to 100 Mbps! Didn't matter at all when i was on FTTC to 40 Mbps - When I can justify the speed upgrade I'll have to replace .

Yes, I don't see how they get away advertising them as AV200 or even AV600 when in fact they only have physical 100Mb ports!

When I can justify the speed upgrade I'll have to replace .

Even then you will still struggle to get fast speeds. I have a pair of AV1300 powerlines that I use occasionally. They actually have gigabit ethernet ports but in reality they still dont actually achieve much better than around 150Mb when on the same electrical circuit. Put them on different circuits they reduce to around 50Mb, via different RCDs (split load cons unit) lucky to get >25Mb.

There's another thread around where someone has bought a recent high spec pair and is getting 200Mb but I guess they weren't cheap!

@davidj66

I use powerline adapter TP-Link TL-4010 AV600, which I think are the same as yours. they were purchased in VDSL days.

With Full Fibre 900/100 , speedtest results is around 94 Mbps Up and down, which around the maximum speed achievable.

The adapters are behind the same RCD with two MCD between them.

Syncing AV200 and AV600 products together can cause issues, with the slower adapters restricting the speed of the faster adapters.
