Hi,

I am using a EE 4G SIM Card in my TP-Link MR600 V2, and my ping on my PC (Ethernet) will spike up in to the millions for a few seconds and then go back to normal, but will drop me out of any games, etc that I am doing due to the massive delay. I have tried the SIM Card in the original EE Router that I was sent and I have no issues, it is only when I put the SIM Card in my MR600 V2. I contacted TP-Link support and they said to request a replacement from Amazon which I have done and it arrived today, but I am still having the same issues. I would like to use my MR600 V2 as I get faster speeds with it, but if I can't fix this ping issue I will just have to use the EE Router. I noticed that the TP-Link Router is Cat 6, and I am using a Cat 5e Ethernet Cable, does that matter?

If anyone could help me figure out what is going wrong it would be greatly appreciated.

Thank you.
