-i am on wifi

-my brother is on wifi

-i am on talktalk

-me and my brother are both using a tp-link wn821n

dude I have the same issue. Talktalk is the worst ISP in the UK. I would advise to choose a different broadband provider.

Don't know much about TalkTalk, but I do know that when I reach close to my data cap with my ISP (Cox) they begin throttling the connection speed severely. You may be able to reset your IP and evade throttling if that is the case.

not that i'm an expert but some of the issues you said sound like a wifi issue not a isp one your rooter can only send information to one device at a time thats where the lag comes from.My suggestion which would be wire it up won't be very practical for you but its the only way i know of to reduce that issue.
Also from the sounds of it Talk talk might be throttling you an issue my friend has when we game

Mine is Talktalk as well however I discussed with my parents to change and we're going to be using EE (which is Orange & T-mobile) broadband from tomorrow onwards

 

Talktalk doesn't have a data cap however like @gmangigson wrote. Talktalk have a common issue of throttling the data speeds which is annoying.
