Hi, I'm a mum who's desperately trying to improve our 'ping' so my son can game.  Sometimes it's great and as low as 60 but then it'll shoot up to 700 and this week over 1200. I've tried to find out why it does this but I'm struggling. I'm using a vodafone unlimited sim card in the MR600 v3. I've spent 12 months discussing it with Vodafone but they say its not them. The PS5 is wired i to the router, however, we get the same results on wifi stuff.  Are there any alterations I can make to the settings on the router? Firmware says it's up to date. We have a BT mesh attached.
You will need to give me full & clear instructions as I don't know the abbreviation terms etc.. I hope there is someone out there who can help. Thanks
