I have a frustrating internet connectivity problem. It usually happens when I am streaming netflix over wifi from a D-Link router (DSL-2554N). Other users can still be using the router, including streaming, while this particular laptop loses the internet. The wifi connection always indicates the strongest signal, and it is an all-or-nothing problem. Sometimes the wifi thing on the laptop indicates I am disconnected. Sometimes it still indicates there is a connection.

It is intermittent, which makes it hard to diagnose to begin with, but then on top of that every trick I try works sometimes, but not always. So every time I think I have it figured out it happens again and the old solution doesn't work any more. The following have appeared to work at least once:

* windows network diagnostics
* rebooting the laptop
* rebooting the router
* moving the laptop
* unplugging the power lead to the laptop

Waiting does not seem to fix the problem, so I doubt these are timing flukes. If I switch to another wifi source such as a mobile phone, every time I try to reconnect to the router it is not working.

The router also occasionally cuts out for everyone, and I think that sometimes my attempts to fix my problem causes it to cut out for other people (going by the timing).

I am still not sure whether it is a problem with the laptop or the router, or some kind of interaction between them.

I have no real idea but I hate DLINK modems. You could check that you have the latest modem firmware version and that there are not a lot of people saying that it does not work.

Fairly common for DLINK software to be rubbish, they normally take a long time to admit that there is a problem and much longer to fix problems and mostly only fix it for their most recent products though they are happy enough to break older modems.

Maybe someone else is freeloading on your WiFi ?

A freeloader is usually a neighbor - not necessarily a Security Threat Operative.

Might ASIO be investigating you ?
