Try theses options: ( turn off and on the power of your router / restart your laptop ) - to refresh all. See also if other computer and laptop can connect to the internet thru the same router just to isolate.

1. use your wired connection first ( rj45 ). Unplug and replug both ends of the cable from the router and from your laptop. Restart your computer. Then check if its ok.

2. Try to do a loop back test to check if your network card and the tcp/ip is working properly. To do a loop back test, go to command prompt and just type " ping 127.0.0.1 " and press enter. It should reply and should tell you 0% loss. If there's an error then disable and enable your LAN ( Local Area Connection ).

3. Do " flush dns". Go to command prompt again, then type " ipconfig /flushdns" then press enter.

Can I connect my HP PSC1510 to my BT Homehub v1?


yes, you can. I have my printer connect to my hub and my desktop and I can print from my laptop wirelessly.
You will need your all in one connected via a printer or USB cable to a computer AND also connected to your hub. Then, go to the computer that is connected through a cable to the all in one. Your all in one should have some way to configure its IP address. I have my printer configured as 192.168.1.4 and it's plugged into the 4th port of my hub. Check if this works.

My hp lap top wont connect to the internet through the usb the ethernet or wireless and it was working fine until 24 hours ago. I think it may be the network adapter. I re installed the driver for it but...


Try turning off the wireless router fo 30 secs and then power it up again. When the LEDs light up, then boot up the HP laptop.
If this doesn't work, then check the laptop to see if the wireless router issued the HP laptop with an IP address. to do this - click on Start - Run - type cmd and press Enter. This will open a DOS command box, then type ipconfig and press Enter.
If the IP address returns 0.0.0.0 then the wireless router didn't issue the HP with an IP address and either the wireless router is faulty or the wireless card is faulty or it has lost its LAN configuration.
If the wireless router LEDs are all on, try connecting a LAN cable direct to the LAN port on the router and the laptop to see if it connects to the Internet. If it connects then install the latest wireless card driver and configure it with the wireless router's settings.

Download to my laptop


connect it via usb cable, install the relevant drivers that came with the printer and and you can send anything to print.

or wirelessly, connect printer to your wireless router using rj45 cable (cat5)...and then find the ip address....then using the printer and scanner option install it, but you will need the drivers (cd) again.

i hope this helps and is not tooo confusing!...lol

No wireless networks found in range


Are all the LEDs on the wireless router are on?
When you reset the wireless router wait at least 1/2 min before powering the router up.
Right click on the wireless connection and click on Repair, this will force the wireless router to issue a new IP address to the wireless card. If the the red x is still on the wireless conection then :-
To check if the wireless card can communicate with the wireless router, ping the IP address of the wireless router, (this is the IP address that is used to login and configure the wireless router) if you get no reply and all packets are lost, then connect a network cable from the laptop's RJ45 port to the wireless router's RJ45 port and do the ping test again.
If you still get no reply and lost packets then most likely you have a faulty wireless router.
Get back to me on the results of the tests and I can then advise what to do next.

Laptop can't aquire IP address


This sounds to be a compatibility issue with either the wireless software or wireless card. Check to see if there are any updated drivers for the wireless card at IBM's support site. If there aren't any or the card still doesn't work after the updated drivers are installed, then you might try a different/newer internal wireless card, or a universal external wireless card for use with your home system.
