I will warn you in advance as I am a serious novice when it comes to networks on the PC.
My problem is this. I've had a long term issue with my internet at my house. It frequently disconnects and long periods of time where it's extremely slow. Tests on pingtest.net and speedtest.net confirm something is seriously wrong. The results show I have 400ms to the closest testing server in Vietnam, other servers are around the same. Yet on speedtest it shows I'm getting 6.8M on an 8M connection from PCCW.
So anyway I've called PCCW to come and fix my internet about 8 times now and this is seriously not an exaggeration. I started to think this was a waste of time and as I suspected the modems PCCW provide to customers are complete rubbish. One of the tech guys who came to my place claimed they replace broken modems and send them out to other people's houses. Which probably explains why even with a replaced modem I am frequently having issues.
So seeing that PCCW were a waste of time I set off to Sham Shui Po to buy a router with WIFI capabilities to directly connect to the internet. However it seems like I can't do this without first connecting the telephone line to my PCCW modem. Then connecting that to my Router and having a cable go to my PC.
Have I made a big mistake in purchasing a router to assume that it can operate as a modem? :/
