Hi there,

Experiencing a big problem with my WLAN connection which has been ongoing now for around a month.
I'm having trouble with a very inconsistent connection.

For starters, upon turning the laptop on its 50/50 weather I will successfully connect to my internet. once connected I continually disconnect and reconnect, never reaching a point of stability, the longest it will go for without hitching is around 30 minutes, and after that point it will repeat the above process in one or two minute cycles, making using the internet impossible.

After various checks listed below I can confirm that this is NOT a router problem:

- Multiple other devices around the house connect without the same problem
- Have tried resetting and rebooting both modem and router with no outcome
- Used new Ethernet cables, and checked other wires for kinks or damage
- Tried changing router frequency and channel for better connectivity with no results
- Tried changing location of router, moving it closer to the laptop for greater signal strength with no positive results

Each time it disconnects I go through a laborious repetitive task of trouble shooting and while sometimes it fixes the problem, it does so only temporarily.

Checks and updates made to computer are as follows:

- Installed latest drivers for my network card
- Installed latest BIOS for my laptop
- Tried un-installing and deleting driver software through device manager in case of a corrupted driver, upon re-boot works temporarily and then fails within the first 5 minutes
- Tried using windows trouble shooter, which sometimes shows a message about my default gateway, i have no idea what it means though
- Tried using other means of checking, connectivity doctor etc, no results
- Tried resetting the network adapters
- Tried using an earlier version of the network card to check if new drivers were the problem - no results
- Tried resetting IP addresses in case of IP conflicts with other devices in the house, no results
- Performed hundreds of reboots

I would like to stress that when using the LAN on my laptop my connection is completely fine and I experience no interruptions, I have also contacted my ISP to ask if there are network maintenance tasks going on and to check if the internet I am receiving is consistent.

Laptop Spec :-

Toshiba Satellite Pro L550
Network adapter: Realtek RTL8191SE
OS: Windows 7 x32bit

The whole process is infuriating and i'm at my wits end as to what to do, is my network card buggered?

N.B

Could this be to do with a problem such as dust inside my laptop on the card, causing interference?
The problem is far more prolific when I use skype - could be a bandwidth problem?

Open to many suggestions, and all help will be appreciated.

Thank you.
