Actually I haven't tried resetting it to its factory state yet but after you listen to this new development, I guess I should. To answer all of the questions:
1. The Dell Inspiron Desktop
is connected to the 2wire 2700HG by a 10m ethernet cable (5m<Distance of PC to router<10m)
2. I have already disabled IPv6 and the two other Link Protocol (can't remember their names) but it doesn't work.
3. I get a perfectly logical (and assigned IP by my router): 192.
4. I have compared both IPCONFIG /ALL logs of the "unable to connect" and "able to" states; unfortunately both are the same.
5. The PC doesn't have a wireless card so I cannot see other networks. Sorry for not making it clear in the beginning.
6. Firewall is disabled and Norton Internet Security (which comes with the PC) uninstalled, with no results. AVG Antivirus however, is installed.
7. The wireless gateway (2wire 2700HG) is a souped-down version that is bundled along by my ISP, Singnet (http://www.singnet.com.sg
). I couldn't find the absolute technical specs online but this is the closest I could get: User Guide
Sorry to put you guys through the long post
but now for the good story!
The Dell engineer came down this evening (1930hours; +8GMT) to have a look-see at my PC. Anyway, to facilitate inspection , I had moved out the desktop from my bedroom to the living room's desk, right beside the router. I switched on the PC before the guy came, just for stand-by's sake and to my surprise, the internet connection was WORKING!
Logically, the Dell guy was surprised (and so was the person whom he reported to). After running some checks and seeing that nothing was wrong, he left. So I shifted the PC happily back into my room and started it up again.
Guess what? The internet stopped working again.
Just by changing distance alone? I'm befuddled.
The only variables were:
1. the distance of the PC to router by ethernet cable
2. different ethernet cables
Yet 2. doesn't make such a difference anymore after I used distance as a variable and kept the cable a constant. The results I get was the same:
further distance (<10m) = fail. network shows connected to internet and local but takes forever to load
shorter dist. (side by side) = pass.
Enlighten me pls!
