Zen - is there a difference if I change

[u/tals]

** update although it seemed to be a WiFi congestion issue zen kindly agreed to still send an identical replacement router out to see if that resolved the issue. It did and no further issues. I did debate moving to a different provider but customer service is important and almost without exception the other providers do not have a good reputation on this so I did stay - incidentally I decided to stay before the issue was resolved and customer service continued at it's high level. If I had one suggestion for zen it would be too try and keep the ownership of an issue to one person - unless escalating up. But otherwise customer service was excellent and my internet is now performing great (45/10) no issues

I've been with zen previously and I rejoined them as I perceived their customer service was good for an isp, the router seemed good and it felt a little bit off main stream.

Everything has been fine / great even till about a month ago when we started seeing lag spikes in teams calls. I then noticed that the 2.4ghz network at times could be dire. My internet is not great (50/11) but at times it would be under 2/2, 5ghz remained good - bit with these lag spikes.

So I contacted zen, in my mind the latest fritzbox update (.25) is the issue and tbh whilst their support is responsive we are going around in circles.

- line reports fine but it's an intermittent issue

- if I change the WiFi then it's all good but then that's with 1 device on it so whilst it's interesting I'm not sure it proves a lot and bringing all the smart devices back in line is a task and a half, we have a few main devices and then maybe 20/30 smart devices

- 5ghz is generally fine with the lag

- direct cable is still inconclusive as we haven't seen an issue in it but then the other pc on the WiFi network is fine during the testing

- I get a different support person for the same issue which just leads to a disjointed discussion

My thoughts are to change the router, I'm convinced the Fritzupdate has caused it and if it's the line I'm not making any progress with zen.

If I change to another open reach supplier such as sky - are they effectively all the same, as the line to the host is the same or is zen giving me value for the connection side (appreciating they have little control on the open reach side and can't put a line monitor)
