I have an extremely annoying issue with my wi-fi netowrk network card and I have no clue where it's coming from.
I'm running Windows 8. The wi-fi networks at my home and office work perfect and I haven't had a single issue with them. I recently started travelling a lot and tried using wi-fi on various locations such as open wi-fi on airpoirts, secured networks in hotels, cafes, guest homes etc. Most of them are not workable. Here's what's happening:
I can usually connect the first time I try, but after a few minutes, and hour top I get kicked out of the netowork or end up with "Limited" access. When I try to reconnect the it goes into and endless "connecting" state. Trying to disconnect hangs the pane and no actions are possible until I:
1. Restart the explorer.exe process, which it "Not responding"
2. Disable and Enable the wireless adapter though the Device Manager
After that in case of some networks I can connect again for a few minutes, but then I all repeats all over OR I cannot connect back at all.
I have tried using A LOT of networks in various places, and I'd say with about 80-85% I expirience the described issue.
I case of some of the networks I had a chance ot connet by wire and they were working perfectly. Often I have other people around with me and of course I'm the only one facing the issue, it's not that I have really back luck for wi-fi networks. Plus my phone connects to majority of them without issue.
In many cases when I switch networks I need to manually run ipconfig /renew and ipconfig /flushdns, before being able to connect to anything.
The wifi adapter is a Intel Centrino Ultimate-N 6300 AGN on a Lenovo W510. The driver version is 18.104.22.168. I've seen 15.x version available for download from both Intel and Lenovo sites, but when trying to install it I got info, that I alread have a newer version of the driver.
Unintalling the driver and letting windows reinstall it does not solve the issue.
I ran out of options on what to check and how to debug this further. What are your thoughts on this?
Just to rule out Windows 8 as the culprit, I would boot a live Linux CD, say Ubuntu, and see if that works better and more consistently. In fact, install it to a bootable USB flash drive w/ say Yumi Multiboot ( http://www.pendrivelinux.com/yumi-multiboot-usb-creator... ) for the greatest convenience.
Another option would be to carry a travel/nano router, one that can be configured for client mode and patched to your laptop’s ethernet port (which we know works). This will push the wireless OUTSIDE the laptop/OS creating some independence between the two. I always keep one w/ me as a backup, and in some cases, use it for wired connections as well so I can establish my own local wireless AP in the room.
