Rather then fill up the Today Thread with my router woes, I thought I'd start a general router thread.

Summary - my TP-Link is starting to become unreliable and is pissing me off. I'm OK to change it even if that doesn't fix things.

I have been looking around and the Netgear R8000 looks like it would do.

https://www.amazon.co.uk/NETGEAR-R8000- ... k+X6+R8000

Any comments? Other suggestions? The Apple router gets surprisingly good reviews - but nahhh. Be quick, I need to order by early afternoon to get it tomorrow.

Overkill mate, I doubt very much you have a client device able to take advantage of it's full spec, and that 'full spec' is a bit bullshitty.
3.2Gb/s combined speed is the same as Honda claiming my car can do 320mph by simply adding up what speed it can do in each gear.
See here: https://www.cnet.com/uk/products/netgea ... er/review/
(I suspect the reason behind the poor range is down to them needing to keep the power low in order to avoid melting the plastic case. Some enterprise devices of similar spec use the chassis as a heatsink in order to be able maintain good power levels and range.)

Some sensible options: https://beta.thewirecutter.com/reviews/ ... st-people/

I always get something more than needed, be it a bigger disk drive, faster CPU and so on. But thanks for the comment and suggestion. I can include that in my deliberations.

Re. what you just typed in Today:

The upstairs wire was partly hanging out. It is clipped in tightly now. The signal strengths are slightly variable but very small changes. 2.4 is -55ish and 5 is -78, so quite weak. It picks up three other spots. Two are only seen every few minutes and have strength about -88. Another over the road pops in now and again at -88. On very rare occasions it sees a VM and Sky network but they've not shown up lately. I have no idea whether any are hidden because I can't see them ;) I'd go for ac over n. Might as well.

That's a 4x4 MIMO device and your most up to date client device (Mac Book) only supports 3x3 MIMO, so you'll top out at around 800.

Hidden networks would still show up as 'unknown'.
Co-Channel interference won't be an issue from those other networks, they're very weak, but you wouldn't be able to detect other interference sources such as a flaky electrical contact.

Is there anything unusual in the System Log? (Router System Tools>System Log)

It means 0 to me but here is the latest log section:

--edit-- log removed after Wooster had browsed it to save all that scrolling.

Obviously there is more.

Speaking too soon as I do, it has been fine for the last five hours or so. It probably spotted I was looking at replacements ;)

Well, it shows you have problems mate, but not much more than you already know.

The Sonos, Nintendo, Apple, Samsung etc. devices I assume are using WiFi?
What is happening is that your wireless devices are asking for IP addresses far more often than normal, and some of the offers are being rejected (NAK = Not Acknowledged), two of them from different Sonos devices.

From what I gather, that main Sonos device can issue IP addresses to clients via DHCP, which might be causing a conflict if the DHCP server is also running on the TP-Link (the devices are jumping between DHCP pools).
Quick test would be to turn them off for a while.

Something else to try is to remove any IP & Mac Bindings (Menu of the same name) from the TP-Link as well.
I was working on configuring a few devices from the same vendor recently and found that the TP-Link stopped issuing IP addresses to them and I suspect that it's not using the full MAC address to do this, just the first half which is the Vendor ID.
(This is how I identified the hardware in play and you also have 2x Apple devices, so the IP & MAC binding might be the problem...if it's used. It might also be worth removing any DHCP reservations as well.)

Finally, it might just be the case that the router has burned out, so everything is flapping up and down like a flaky fluorescent lamp. :)

Power supply in the house OK?

The general power is fine as far as I know. The Sonos works by having one item (in this case a Bridge) wired, which then controls all the other elements on it's own mesh network, but they get an IP from the router. I did have one other component wired in but not now. How it works (scroll down) https://www.lifewire.com/what-is-sonos-1847440

It has been stable for the last hours now. I'm beginning to think it might be a random thing or the router is starting to go. The wifi signal is lower than I recall it used to be. Anything that can be wired has a cable.

-edit- Again, your devices won't be able to utilise anything near the spec that thing has mate, you're paying for a capability that may never be a reality on a client device.
You have 3x3 MIMO and 64QAM (1024QAM capable chipsets aren't even standard yet, so it's a pre-pre-802.11ax spec).*
I'd rather buy something I could use, with tried and tested (reliable) hardware than take a punt on an expensive consumer test platform. ;)

The more I read about those Sonos devices, the less convinced I am about their worth.

Anyhoo, closing thoughts are to make sure RTSP is enabled on the TP-Link 'Basic Security' settings.
The 2.4Ghz mesh network they set up when wired is a bit of an antique and can cause network problems, and the fact that it's on 2.4GHz means it stands a chance of causing or suffering wireless interference if there is another wireless router present.
It also in no way helps that it can't be identified by normal wifi scanning tools. (It's insane that you'd need to use a Spectrum Analyser to identify it)

Look at the plight of that thing.
...it's so big that I don't think they've even managed to make a USB one yet. :D

Don't you badmouth my Sonos <shakes fist> I love it. Well I'm not actually making a real threat. I'd never beat a Scotsman even if his organs were all clogged by fried food, white cider and no veg.

I ordered that last TP-Link I mentioned. I know it is more than needed so now I'll need a new laptop etc. ;) I'll own up to it being a waste of time and money if things stay the same. Then you can mention Sonos again :D

This'un has been up and down a lot this evening. Restarts needed. Arse.

Yesterday evening, I turned off the 5GHz. It was still flaky. This morning, after several restarts, I took action on something Wooster said and moved the power plug from the UPS it was on to a standard power board. It has stayed up since then, albeit with a weak and weedy wifi signal. I'm happy to give Wooster the credit but it isn't definitely the cause as there hasn't been long enough to prove it. It seems likely, though. Either way, I'm still waiting for Amazon to drop the new one off. I'll do a factory reset on the current one then tuck it aside as a spare. You never know if it will be needed. A job for the morning, unless this one dicks about again beforehand.
