Limited Internet *sigh*

by crank_girl / February 19, 2014 5:07 PM PST


I have a brand spanking new lenovo z510 i7 that will not, despite my best efforts, connect to the Internet.

What I've got:

Tp-link wdr3600 running 2.4ghz on channel 3 mixed bg, wep. I get the "this connection is limited" message on wifi and ethernet, even when running latest Ubuntu from a live USB.

What I've tried:

Disabling/enabling atheros card; removing/reinstalling drivers; installing Windows 7 wifi card drivers; changing/removing security on router; rebooting everything like a gazillion times; standing on one leg whilst cursing loudly; flushing and renewing things via command line; loads of other stuff that I'm only likely to recall under torture.

... I've spent hours changing various settings on both router and laptop with no success. Oh, it DOES work when I use my mobile phone as a hotspot but other than that it has not connected to the Internet.

Should I send it back? Is this problem likely to occur again if I get a replacement? Shame because I really like it.

Any new suggestions or opinions gratefully received. Happy

Sorry...should also have said

I'm now running wpa2 with tkip - though I've tried every other flavour of security. Dchp is running and I've assigned a permanent network address. I don't have Mac filtering or anything like that running. My ssid is a reasonable length.

The card is an atheros AR9485.

Well lady you can do many things like changing your IP and DNS address, or you may use some kind of software software.
There are many softwares available in the market that are meant to keep check of your problems of limited access to the network...
You can try the link i am giving below:

Another thing to look at is security software and settings, you said nothing of what is being used, this could well be germane to security software.

TRUE!!! Just last week

I had the fun time of a WEP (that's no protection!!!) network and the password was accepted and naturally, no connect to the internet.

But here there is something odd going on with the Ethernet not working. I wonder if the WiFi is enabled when the Ethernet was tried. That can cause this failure.

OK, I can't guess what settings the router has but if a SECURITY CONSCIOUS (well meaning person) used MAC FILTERING what you noted should happen.

-> Try the router defaults then move to 802.11g only to avoid an old issue and then to WPA2 AES personal security. Keep the SSID and passwords to alpha numerics.

Thanks for your reply.

No, no Mac filtering. And all security switched off too (to answer pgc3's question). I've tried every combination of security setting, broadcast channel, frequency, ssid name etc. Nada, nein, ne rien, zip.

I went and bought a tp-link wlan USB as I figured I'd probably be able to fix it if I could get it connected to the Internet but that didn't work either.

I was about to throw the whole lot into a bath and climb in with it when I remembered I had the rubbish old router I got with plusnet. I plugged it in, switched the other router off et voila, the Internet appeared. Great but everything else, several tablets, phones, NAS, ftp and torrent client, all configured to work through the router. So I'm just about to experiment to see if I can use the old router as a bridge somewhere so I can use new router AND keep the new laptop online.

I did think perhaps that this was a driver issue but now I'm more inclined to think it's a dhcp problem in Windows 8.
