hi,
i lived in apartment. recently, my uncle who lives in another block, approx 300meter from my apartment, has agreed to share his 5mb Unifi connection with me. FYI, I already change the stock Dlink 615 to TPLink WR841ND and pair with another wireless router (in my house to act as repeater) and I successfully can connect to the internet.

Only problem is that my internet speed in my house drop drastically if compare the internet line at my uncle place. From Speedtest.net, i can get around 2mb of download/upload but at my uncle place can easily get around 4/5Mb of download/upload.

I believe the speed drop because using the repeater.

What do I need to invest in term of equiptment? I'm thinking of getting another antenna that have better dbi to replace the stock Tplink WR841ND which is only 5dbi. Do u have a suggestion how can i get same speed as my uncle internet line?
