'Default Gateway not Available'

[Scotty]

Alright lads, heres something for you all to ponder over, i'm completely lost;

Its been fine, no problems whatsoever for the whole time of me using this laptop to connect to the internet.

However now, its randomly decided to drop out on me, I'm connecting wirelessly, and as soon as I run the troubleshooter to automatically fix the connection, it finds the 'Default Gateway is not available', it then resets the wireless adapter and I'm back online.
During the time of connection loss, all other connections on the network remain online, so I know its my laptop-specific.

Using Windows 7.
This occurs every few minutes generally, and its really pissing me off! Like I said, its been fine up to now, and I have not changed ANY settings.
Any ideas?

I don't know much about Windows 7 beyond it being a bloated mess and I haven't used Wireless a lot over the years, but perhaps entering the settings manually might fix things.

I'm not sure if this is different on wireless networks, but go to the Control Panel and click Network, right click the wireless connection and then "Properties" in the menu that appears, click "TCP/IP" once and press the "Properties" button.

Everything should be set as Automatic, before fiddling with anything press the Windows and R key at the same time (Assuming you have a Windows key, most of my systems do not, if your system doesn't have one, click the Start menu and select Run) and type CMD in the Run box that appears and press Enter, type
ipconfig -all
Press enter and a list of connection details should appear, make a note of the ones for the Wireless connection, copy and paste to a text file or something.

Now all you need to do is go back to the properties Window for TCP/IP and set everything to manual, enter the settings you found using IPCONFIG and press OK, after this just keep hitting OK buttons until everything has closed.

If this stops the internet working at all I will be puzzled by that, but you can always put things back on Automatic again, if this fixes it I would be suspicious of the hardware and software thinking that something was wrong with it though it may be interference and if it doesn't fix it, the same applies.

Why let facts get in the way of anything.. LOL

But yeh your advice is good, assign the laptop a manual IP address rather than relying on DHCP and you will hopefully have less issues.

A quick guide here:

Okay this was my first initial thoughts before even posting here, maybe I should have put this in the first initial message.

In other words, it doesn't work.
I don't suppose wireless signal stregnth could do this? Mine is quite low, even though it sill says connected, but with 'Limited Connectively'

If you guys think it could be the signal, I have a idea to make it good.
Thanks for the advice HT.

best thing to do also is check your DHCP settings in your router, also change your wireless security key.
once you have changed the security key make sure the problem machine is the first to be set up using the new key.

However, if all of a sudden your connection does drop out then I would suggest moving your router, it could be some kind of interference and since you have a low signal this would be apparent, maybe move the laptop closer to the Wireless Access Point, interference can be caused by anything - electrical wires, boilers, TV Aerials, Home & mobile phones, I would just suggest moving the laptop closer maybe even sit right next to the Wireless for a day and see if it drops out if it does then there is a problem with your Settings.

Hope this helps

Its not the router, as I said before - No other computer/console on the network is affected. Only my laptop.
This is getting beyond a joke, and I have now eliminated signal strength as a issue.

I'm starting to think my wireless network card has malfunctioned. I have the latest drivers and I'm at  a loss as what to do next.
Luckily I have been paying a monthly payment for laptop cover, so it might be time for me to give them a call to fix this shit.
I have never had this problem before, its so random!

this may sound like a strange suggestion but change the wireless channel in your router.
if anyone close by has just installed a wireless router and it is on a similar channel it can interfere with other peoples wireless signals especially if they have weak signals.
to ensure no signal overlap you should normally only use channels 1, 7, or 13

I reset the router, and all problems stopped. So strange.
