Broken wireless card

Hello. I just broke my wireless TL-WN550G card by mistakenly desoldering a few capacitors before the anthenna. I also made myself a homebrew cantenna. I tried to fix the desoldered capacitor by just avoiding it and soldering the two connectors together.. But now i'm unable to receive packets without CRC errors. Transmitting seems to be good. By the way the cable that leads to the cantena is around 7 meters long.. could this cause the problem? I can scan for networks and i can find some but im unable to connect.. can you please tell me how can i fix this problem? should i solder a new capacitor? if so, what is its value? im sending some pictures with the problematic capacitor slot and the cantenna.. please help me. I only need ANT1 because thats where i solder the cantenna.
