Yesterday, I was just moved from my Telecom Go Large plan onto Xnet from a recommendation from a friend.
Sometimes with Go Large, my internet becomes limited with slow speeds 300kbps (shows in ADSL router) while sometimes it shows up as 3000-4000kbps. 

I just signed onto Xnet and have found that downloading from Rapidshare, Megaupload or any server would result in slower speeds (maximum 90-100 kilobytes/second) while I have always been able to download at least 150kilobytes/second with xtra with connected with 3000-4000kbps.

While I get 90 kilobytes/second, my router connects at 4000kbps so I fear there is something wrong. I have read around and there seems to have been problems with Xnet's speed especially internationally. I tried downloading Flashget and it would not go above 20 kilobytes/second.

I wanted to signup with something that had similar speeds to what Go Large had, which was also 4000kbps down and 128kbps up. With this Xnet connection, I am getting those slow download speeds during peak hours (ones I pay for at $1.53 per GB). While I like the 75GB free offpeak usage, I'd like a fast connection too to use during the day.

Does Xnet limit the speed of downloads or something? Also, if I cancel on Monday, would they allow me? Would Telecom also give back my Go Large plan? I guess I'll give a call on Monday to find out. I hope so since it's only been 1 day so far. But if someone has a definite answer please tell.

I don't remember having slower speeds when on Go Large when it's connected at 4000kbps all day round. Is this because of Xnet not buying though bandwidth or something, and if so would it be better off if I got internet with Telecom? (Since if I recall correctly, they resell the broadband to other ISPs?)

Any help would be greatly appreciated :)
Edit:I have also heard that while ISP limit the 128kbps upload, it also significantly limits the upload. So if I get the FS/FS option, would this mean that I could be expecting a bigger increase in speed? Since I would theoretically be able to connect at a maximum of 7.6mbps instead of 4mbps... A little confusing since it's advertised as FS (full speed) download for both...
