Broadband Speed drops during evening

[ARB2]

I switched from another broadband provider in late May of this year to Sky and also purchased a Skyglass tv.

We then experienced issues with the TV picture freezing for several seconds (sound continued). This was very noticeable between 7:00 PM and 9:00 PM but also occured at other times.

I soon realised that issue was with Broadband performance and so called sky.

I Have now had approx. 18 calls to sky, and a visit from an Sky engineer and also from an OutReach engineer. Have changed hubs four times on advice from sky support.. 

Checking the speed I consistently see it dropping from approx. 6:00 PM every evening. During the day it is normally around 60 Mb/s and then in the evening drops to as low as single digits, on one  occasion it was down to 2.5 (2 point 5) Mb/s - this speed confirmed by Sky technician.

Both technicians visits could not find and definite issue, and speed seemed to be OK - but as these were during the day that it what I expected.

Broadband or WiFi?

The timings might suggest adverse impact from another device (potentially not even within your own household)

[ARB2]

to eliminate the possible WiFi cause at one stage I connected the TV using Ethernet via TPLink connections and this made no difference.

Also my recent monitoring of performance was based on my laptop connected to the router directly with an ethernet cable.

@ARB2 Even though you are monitoring it, you need to use the Stat's screen and watch what is going on with the whole network with regards to the wan traffic and what if any device is creating it. Tp-Link what device is it that you have!

[ARB2]

sorry for the ignorance but what / where is the stat's screen. Also will this show external network - i.e. what is happening external to my property? 

The TP link was a AV1000Gigabit Passthrough Adapter - but this is no longer in use as the Sky engineer who visited suggested this could be causing an issue.

Incoming signal is currently at 12 Mbps (22:26 on 31st July)

@ARB2 You will find it Maintenance, Router Status, down to the bottom off the screen then show statistics, you can watch the traffic In Out for all the ports, WAN the router, LAN / 2.4Ghz / 5Ghz the 5Ghz may have an oops on it goes away traffic wise on the screen but working fine just not reporting the findings! WAN is the combination for all three out/in to the Internet!

TP-Link AV1000's work fine, just had to swap out one of the AV600 few weeks ago but as could not get the older just got new AV1000's and replaced only the faulty unit, so got the mix match off both but think the AV1000 drops back to AV600 mode operation, only noticable is Tp-Link software gets confused and say's it gets real good speed's and that's a load of tosh for sure!
