Firstly greetings to everyone, I am a new member, but have used bleeping computer as a reference for years.
I hope I'm posting this in the correct part of the forum, but I'm sure someone will move it if it's wrong.
A little background about my IT knowledge. I used to build my own desktops (back in the day), so I've had a little experience. I know that it's not normally the construction, it's generally the interaction between hardware and software which can cause problems.
Anyway back to the problem.
Last night at about 10:00 BST I suddenly lost my network connection on my Acer laptop. At first I didn't think much about it, and assumed it was an ISP problem. About 5 minutes later it connected again.
About half an hour after that it did it again (the dreaded yellow triangle popped up on the network symbol). Again I didn't think much about it, as within a minute or two it was restored. However this has continued to happen at irregular intervals (10 minutes to around half an hour), and continues now.
I've done the normal things like checking other devices when it happens (another Acer laptop (wireless), a desktop (wired), and wireless tablets and phones that are in the house). None of them are losing connection at all.
I've deleted the wireless network, and set a new one up. I've checked the power management settings of the adapter, but so far nothing seems to have worked.
When it happens, the Wireless Network Connection says that I am connected to the router, but no internet access. The Network and Sharing Center has a red cross in the link between the wireless router and the internet. I've set the wireless adapter to a static DNS of 18.104.22.168.
My limited knowledge has now run dry. It's saying I'm connected to the wireless router, but there's no connection to the internet. That would seem to point to router trouble, but every other device in the house is connected without problems. If it is the laptop, or more specifically the wireless adapter, why does it say I'm connected to the wireless router?
Thanks for taking the time to read this.
