Hi smudge41,
Thanks for taking the time to come back and update the thread.
We're pleased to hear that things are better for you now and that you are getting better WiFi speeds using the third party router.
We always take on board the feedback given in the posts we receive so we can collect the information and use it to learn more about the areas we need to improve. We will certainly pass this information along to the relevant teams.
If you have any further issues, pop back and let us know.
Thanks,
