I am just reading this post, because i have a problem with the wifi connection and can not find a solution anywhere.
I use a Poynting Mimo 3 V 15 on the top of my camper, with a 955. Set as a acces point.
At home i was trying to make connection to my Wifi at home, and put the Wifi home interface as main in a client mode. When i connect to the 955 and using the wifi from home i get a speed of less than 5mbits.
When i leave the RUT out the network, and connect with the same device at the same location directly to my Wifi at home, i got 50mbits. I can not find what im doing wrong after 2 weeks ;/ i hope you have an answer.
