Wi-fi dropping repeatedly

I have 200mb connection and when my son watches kids YouTube (connected to router via Wi-fi) it buffers regularly for 2-30 seconds at all times of day. I work on a powerline connection and I experience a dropped connection a few times a day, these last for up to a minute. I recorded a Teams call recently, and even though I have the best theoretical connection of the attendees my video feed was low quality and jumpy - all other attendees video feeds were fine. Apparently that’s how I always appear to them, so they assumed I was on a poor connection  

It’s been like this for a couple of months. I originally thought it was the Wi-fi extenders / powerline, but after I swapped these out for new with no improvement I switched them all off and just used the router on its own. Lo and behold I get the same issues which means it must be a line or router issue.

Any ideas, do I need a new router or do I need to get an engineer out?

My BQM was running ok up to yesterday but is now showing a red block. Here’s the last few days:

Re: Wi-fi dropping repeatedly

Apart from the recent red wall - the earlier BQM looks lovely - far better than mine 🙂

No evidence from that or the stats that there is a network connection issue. So, are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables?

If you don't know, can you check that quality to help diagnose whether it is just a wifi issue or it could be network connection related?

What are the various Hub lights showing/doing when this happens?

Powerlines are not really the best way to build a solid wifi networ un less you are using the very expensive DeVolo Magic ones.

Far better to use a either a…
(1) Mesh System, (2) Wireless router, (3) Wireless access point (4) A combination of (2) & (3).

Re: Wi-fi dropping repeatedly

Thanks John. I wasn’t sure what I was looking at on the BQM to be honest, so good to hear that it looks good to you. Until yesterday at least, not sure why it’s gone all red now - the internet is still working, so I’ll assume it’s a problem on BQM reporting rather than my connection.

It’s not too easy to check the wired vs wireless connections at the same time as the wired connections are via the powerline adaptors (so I wouldn’t be able to rule those out as the cause). I can only really check the Wi-fi with all the adaptors turned off - and that test seemed to suggest that we’re still experiencing the connection dropping off regularly based on my sons whining every time it happened when I left only the hub on for Wi-fi (and he was sat within a few metres of it so not a range issue).

I’m currently using some TP-Link TL-WPA4220’s as powerline adapters and Wi-fi range extenders around the house. Sounds like you’d recommend I invest in a mesh to get a better signal around the house. I’m far from an expert in this area, but a quick google suggests the TP Link Deco P9 would give me a good mesh system for about £150ish. Any idea if that’s a good set up - or would you recommend any alternatives?

Re: Wi-fi dropping repeatedly

Thanks for the suggestion. To be honest, at my age I’m not really interested in something that markets itself as a “system designed to add a fresh and youthful feel to your home”. I’m more interested in the practical application of the product in question, and a quick google of the product suggests it doesn’t really hold up in that area either 😞

Re: Wi-fi dropping repeatedly

Legacy1 does like the Zyxel range 🙂

There are lots of other options for mesh systems that are well regarded on here (and by tech review websites) - particularly the TP-Link Deco M4 or M5 (or M9). My 3 pals all got a 3pack of M5's and are blown away with how easy they were to set up and their wifi performance. Look at what Netgear and Asus offer too.

If you decide to take the plunge... ask again on here for comments on what you like the look of and for help in setting up.

Just like you like the TP-Link range each to their own.
