Last night I was using the Internet but this morning I had no internet access. Since then my BThub3 is now showing that I have internet access - "IPv4 connectivity- Internet/ IPv6 - No Internet Access" but I still cannot open any web pages Error message "This page can't be displayed".

I have an Acer Aspire E1-531 running Win7 with a BThub3 router; BT Broadband Infinity Option1.

Anyone - how do I get my internet access back? Any replies gratefully received.

Beachguide, there is more than one possible cause, but it might be that your service provider is down.

A driver gone bad can also be the cause, and can be fixed by reinstalling the driver for whichever network adaptor you are using.

Are you connecting to the modem via WiFi or Ethernet cable?  Whichever you are using, you can use the other method to see if the problem is with the computer, or the modem or the service.  Also, you could take the computer to a place with public internet access and try to connect there.

Good luck

Thank you both. I've checked the drivers and all seem to be ok. I should have added that I have another notebook and using that I can connect to the internet without any trouble.

The 'status' of my BThub3 shows IPv4 Connectivity Internet and IPv6 Connectivity No Internet Access but I still cannot open any web pages.

Reinstalling the driver(s) can fix the problem, even if they seem to be correct and up to date.  I don't have the experience of the Acer having this issue, but I did have to reinstall the wireless network adaptor driver of an HP Pavilion DV6 (known issue) to fix the lack of wireless connectivity that I experienced.  What happens when you connect to your modem via the ethernet port?  Or to the internet at another location?

It occurs to me that a pretty definitive way to fix the problem could be to reinstall the OS, but that's rather drastic and only to be taken as a last resort, not least because it's so much work (see my guide as to how to do this elsewhere, in reference to a question entitled something like "Downgrading Windows 8" from a few days ago.

Sorry I can't help more at the moment.

Best of luck!

Sorry but with the IPv4 saying it is commented (I usually turn IPv6 off) I don't think the problem is with the PC.

My provider is usually very reliable but occasionly things go wonkey so I have a DOS batch file with just lines of PING -N 2 xxxxx where on the first line the xxxx is the IP adress of the local router, the second, the provider gateway, 3 & 4 the DNS servers (may have more than one but only need to reach one) and the last is a local web page (FQDN not IP).

Running that file tells me very quickly if there is a local problem or something further downstream. It is like connecting a phone at the DEMARC to find a problem. 

ps a quick & dirty check through the DNS servers is just to run NSLOOKUP WWW.ACER.COM

Padgett: Since I've been trying all the suggestions I've been given, IPv4 has sometimes been shown as "Internet Access " and sometimes as "No internet Access". Currently it is showing the latter. Also I can use my wife's netbook browsing the web via the same router without any problems which makes me think the problem lies in the laptop?

Open a DOS box. run IPCONFIG/ALL, copy and paste the result.

This tells me that you can talk to the wireless card and Windows knows that it is there but you are not connected to anything so the next step is to go to Control Panel> Network and Sharing Center and on the left you should have "Manage wireless networks" - click on that ans are any netorks displayed ? Is one local for you ?

If there is then go back to Network and Sharing center & click on "Connect to a network". If the one you want is listed then highlight and click on the connect button that appears (if secured it may ask you for a passphrase).

When it says "connected" you are joined to the router and IPCONFIG should show an IPv4 address

Try this sequence and let us know what happens. If any step does not work we can go there.

BTW I just relized that you never said whethere this is a wired (RJ-45) connection or Wireless, you appear to have both. The above is for a wireless connection, a wired connection should just happen.
