Huawei e398 external antenna Telenor help

Hi,

I'm trying to put the interwebz in at the summer stugan. Just bought service from Telenor today. Cranked 80Mbit/s south of G'burg. Nice! Drove to the summer house (beaches near Halmstad), and I'm getting 64% 4G signal and less than 2Mbit/s. Connected the Poynting 4g Riktantenn (bought at Kjell) to either external antenna socket on the Huawei and I see no difference. I've moved the antenna all over, no dice. No difference.

What am I missing?

I can read Swedish, so all replies appreciated!

I should add that there wasn't anything besides a 'quick start' pamphlet with the modem, and Huawei's site has no support docs for the e398.
