I also using Aztech 600EU,BT 0.60,streamyx 512KB.Now i using his setting.It depend on what torrent u download.

I copy this thing from somewhere.

this mine setting la...not know wether work with u guys..

go to preferences >> advanced >> connection >>
1. set maximum connection to :999999
2. connection to keep per task :999999
3. max half-open TCP connection :999999

then, go to preferences >> advanced >> ip rules >>
1. max session per IP for downloading task :999999

Setting maximum connections to 999999999999999999999999999999999 doesn't mean your speed can go 50000000KBps It will just make your router unecessarily overloaded with connections

The person who instructed you to do that was either fooling you or just plain stupid (no offence)

disaster.
since I follow the port forwarding thing...cannot connect to internet now.
Even when going to the http://192.168.1.1
After entering the username and password to login..

"internal communation error. exiting."

What to do now? 

Called Streamyx tech. support...they ask me to bring the modem to a
PC shop so that they can set it to manual connection 

Does bitcomet restrict full speed dl-ling connection?
I was a bit tornado user, and my dl-ling speed was like 80kB/s on average, max 110kBs. But when using Bitcomet, my speed drop to 5-15kB/s.. Why har?
