[Removed from squad after every mission]

After every mission i get removed from the squads weather with friends or randoms. I recently changed to have a fixed IP if that may be of help. I'm not too sure what causes this but it's more irritating as have to rejoin every time and if my friends sent invites too soon i get stuck in a loading screen. Any help would be much appreciated, thanks

[Weapons and frames not leveling]

'Ello, I've been trying to level weapons for a while to increase mastery but my weapons don't gain any EXP from anyting and sometimes gain an absurd amount for nothing (only hapened once). I've had friends give me tips to level my weapons but nothing has worked so far, warframes and companions don't level either but sometimes do. Not sure what causes it, not sure if this should be in this section of the forum either but was told to put this here
