I assume the laptop is trying to connect wirelessly? What error message do you get when you try and connect?

Hello and welcome.
Firstly your connection will be variable, but not slow, while your line quality is analysed.
I assume that you have a BT Homehub, can you tell us which version please as setting wireless connections up differs.
in addition to the above - a little more info on when you changed from sky , has it worked since you changed from sky ?
Hi shystar i belive its a homehub 3.0 settings type A the latest one if this helps
thank you
Hi Maz_- the only error message seems to be unable to renew ip address

thank you
Hi etaf when i changed from sky my pc was the only one that was able to connect straght away

thank you
Hi etaf when i changed from sky my pc was the only one that was able to connect straght away
And you set the homehub 3 up yourself - correct

lets see the following information from the working PC - and then again from the none working PC
only need to see xirrus screen shot from wireless enabled devices

{ipconfig /all}
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste

{run Xirrus Wi-Fi Inspector} Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools
Direct link to the program is here Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
Full details are here TSG Posting a Screenshot - TSG Library of Knowledge

For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

thats showing as disconnected - can you connect directly to the router and see if that works

remember to do a powercycle - also would be worth seeing xirrus if possible

is the wireless on/off - theres often a switch on laptops or a combination of FN and F keys to toggle on / off

will the laptop work wirelessly anywhere else


How to power cycle

“power cycle” process to reboot or reset the modem/router
  • Switch off all the devices modem, router and computers also unplug their power cables.
  • Wait at least 30 seconds.
  • Plug the power cords back in, but don’t switch them on.
  • First turn on the modem and then wait for it to settle - all lights to become stable.
  • Next switch on the router (if a seperate device ) and the allow the lights to become stabile.
  • Now turn on your computer, You should now be able to access the Internet.
