Hello,

a few months ago I moved and ordered a SIM card with unlimited data to have internet during that time. I needed a 3G/4G router and ordered the TP-LINK TL-MR6400 from Amazon.

I was happy to have workaround internet because it took some time to get normal internet at this location here, but one thing always annoyed me - the speed.

I don't know, if it has something to do with the frequences (I live in Germany), but with the SIM card in the router, I get a download speed of 5-10 Mbit/s and that's really when it's at it's best.

After some time, I starting worrying if it was the right purchase. Also because I saw the TP-LINK MR600 is actually better (for 30-40€ more), so to find out if it has something to do with the router or the SIM card, I put the SIM card in my phone and without changing anything at home, I had a download speed of 30-70 Mbit/s.

So my question is, does it really have something to do with the frequences the router supports? Is it something else? Could it be wrong configuration?

I just want to add, that I tested the speed in the same room and that I didn't do anything different, the position of the router and the phone was basically the same.

Regards
