Hello,

Thanks for confirming. Have you tried resetting the router and then setting it back up again?

Hi,

Can I just check, has this only recently happened (the speed issue) in the last few days/week? Were the speeds ok prior to this on both wifi channels?

This has only happened in the last week or so. Prior to that speeds on both wifi channels were fine

Hi,

Would you like us to send a replacement router for testing purposes to rule this out?

Thanks

I have installed the replacement router but it has made no difference

5Ghz is giving me speeds of 450Mps whereas 2.4Ghz is only giving me speeds of about 35-40Mps if I am lucky.

These are speeds when next to the router.

I have moved router to different positions etc but has made no difference.

What can I try now?

Thank you
