4pm to 11pm is classic peak times, and congestion does come and go like this.
OK - I hadn't known that as I've never had it before.
The speed tests suggests congestion too, of course its possible you have the odd bit of interference causing disconnects on top of speed problems
If you look at http://forums.thinkbroadband.com/zen/t/4509738-poor-... then you will see others with Zen with the same problem. They have one of our tests on their own network, so their support will give you the link and test, to rule out a chunk of the internet as an influence.
Thanks. I've sent a PM to Jon Green, and he responded quickly saying he'd look at my connection tomorrow. Thanks for the suggestion.
NOTE: Wi-Fi slow downs may be caused by congestion in the Wi-Fi bands, hence the usual recommendation where at all possible to connect streaming devices by Ethernet or if you only have a 802.11n router to upgrade to an 802.11ac dual band device or add a wireless access point to handle the wireless side.
For now, we barely use Wi-Fi to be honest - sons usually during the day with their phones/iPads etc. when visiting, and two smart TV's when updating mostly. One of the rare occasions we download a programme was the other night, and it was taking too long, so I did it late that night.
The most use currently is wired connection day and evening, as I work at home.
Be interesting to see if Zen come up with anything - I spent some time talking with Tech services over a few weeks earlier this year, but nothing got resolved. That's when I got a new router, and used the radio to check for interference in the house.
I'll post back if I hear anything useful from Jon Green.
