Again, you're not providing useful information for us to determine anything. In this entire thread you've been repeating that the wireless card works on one provider and not another. You have not told us what hardware is involved, whether your ISP provides all the hardware (modem, wireless router), how the wireless network is configured. Indeed, you still hasn't confirmed that you're talking about a PC card wireless device after being asked by several members repeatedly
, and we have to guess this!
Please answer these questions:
1. What model is your wireless router? Is it provided by your ISP, Plusnet? What model of wireless router were you using with Sky? Was it provided by the ISP? Have you updated firmware on either routers?
2. How is the wireless network configured? Did you take most of the default settings, or did you reconfigure it extensively? Post every single configuration item available to you except your password.
3. What is the symptoms of the problem? What happens when you try to connect to the wireless network? Is there any error message?
4. What exactly did you do to troubleshoot the problem? What steps did you take, and what output did the computer give you for each step?
Remember also, its not just my laptop that doesn't connect, but my PC also?
Oh good, that's the first time you ever mentioned this. How is your PC connected? Is it wired or wireless? What network card is the PC using? How does it not connect? What is the error message, if any?
Without concrete, detailed information from you, we can only guess. And frankly, I'm tired of guessing.
