MR100 or AC797

Hi,

I am temporarily living in Central London and need wifi internet connection, if possible with ethernet. I have a data SIM card from EE but using my mobile phone as a hotspot is not reliable. Was thinking of purchasing one of the above models but unsure which is good enough and most reliable.

I mostly need internet for daily office work (emails etc), social media browsing, streaming Netflix/YouTube and listening to interent radio.

Your opinions will help.

Thanks,

Pavlos
