Not actually, people with good service, keep quiet,
and only people face difficult, posted.

So you see complaints in most posts.

Yes, there are pocket of issues, but to say it is not stable based on some posts that facing issue, already concluded Unifi is not stable, still kind not fair to Unifi.

Although my VIP5 seems to have a stable download/upload speed, there's one issue though. I noticed that after a while of torrenting, it seems that I can't surf the web anymore.

Doing a ping to let's say lowyat.net will receive response but it seems that all my web browsers will not be able to surf any websites. It'll just show that the web server is taking too long to respond.

Anyone have similar experience?

Same here, after restart the modem (aka reconnect also can) will solve it for a while to get you back on the Internet.

Another thing is downloads from major file sharing sites (uploadstation, fileserve, filesonic) all gives me about 40kB/s max, I could get better speeds with Streamyx.

i heard that unifi speed is the best so far.. but for 1 person... rm150 seems not worth it... i rarely use the internet but yet i need the best speed for browsing... huhu.. thinking about to switch my digi broadband to unifi... hmmm....

lol same..even if wanna download all HD videos, need more hard disk space.
