I have a lenovo G505 laptop - it will no longer connect to my BT home hub despite it showing as being available. I suspect it might be to do with the fact that it is has a passkey - I entered it yesterday when prompted and it connected fine, but now I'm not being given the option of entering the key.
I've also tried connected using the BT wifi (as opposed to homehub) but once again it will not connect me. I've been through all the troubleshooting options, and searched under every term I can think of, but nothing is working.

I just got a new Windows 8 laptop, a Lenovo Y510p, and I've been having several wireless issues with it. Pretty early on my computer froze up so I had to force it to shut down. After resolving the issue, I was unable to load any websites, however a flush of the dns cache fixed the problem right up. Fast forward a few hours, and suddenly I can't connect to the router in my dorm room-I just suddenly lost my connection and now I can't reconnect.
My roommate has a router set up for our room connected to an internet jack in the wall. It is configured as WPA2-PSK. I usually connect to this when in the room, but now I can't-windows just says "can't connect to this network". There is wifi throughout the dorm already, which I can connect to just fine, however the signal isn't as strong.
This is a link to my ipconfig : ipconfig - Pastebin.com

I have a brand new Lenovo Ideapad Z585. It has a Broadcom Wireless adapter that will not connect to my home wireless network. I have tried everything I can think of to get it to connect to my Netgear router.
When I run Windows diagnostic tools it tells me that there is a problem with the wireless access point, there isn't I am using another laptop with no issues.
I have done a rescue install and gone through the same problems. This time the diagnostic report tells me I have not chosen a network to connect to despite entering the usual SSID, security type and password details in the network centre.
Networks are detected OK, I click on my network, am asked for the password and weither I wanted to share on the network, click ok and after a couple of seconds I am advised 'could not connect to network'
I have spent about 6 hours today trying to resolve this. The ethernet works fine.
I am completely ignorant of WIndows 8, this being my first computer to use it.

I installed Windows 8 in my notebook, Lenovo 3000 G430. It worked fine for a while, but after I had a long shutdown, when reboot again, the Wifi was not working. The drivers are still there, and when activating the Wifi from Fn F5, it goes to Airplane Mode.
I removed Windows 8 and reinstalled Window Vista, the Wifi came back and working fine. I tried this many round, it produced the same result.
I believe that it is compatible issue with the driver for the Wifi. Can some one able to provide the driver for BROADCOM Wireless 802.11g for Windows 8?

Lenovo P585. The wifi does not work all that well...... It either switches between 2-4 bars infrequently or it takes 10-20 seconds for a page to start loading. My drivers are up to date.
Recently it has gotten worse and sometimes it says I have no connection all together. My tablet and other computers connect fine enough and don't have the same 10-20 delay for a page to load.
Also a torrent site I go to frequently has not been loadable for over a month. The torrents also don't seed. The site will only load on my Windows Phone 8 with wifi on and 4g off. This lead me to believe that my ISP is not blocking the site.
I get this on any PCs in the house: Error code: ERR_NETWORK_ACCESS_DENIED
Not sure why this happens, every other page loads fine.

I have recently up-graded my laptop from 8 to 8.1. Since that time, the laptop will not automatically connect to my home wifi. If I try to connect manually, it will say "unable to connect to network" and that's it, no more clues! The only way I can connect is by selecting 'restart' and then it will re-boot and connect automatically. If I 'shut-down' after use (or hibernate) it will not re-connect until I have selected 're-start' which is time consuming and annoying!

I have a new Lumix GX7 camera which I'm trying to connect to a Dell laptop running Windows8.1 using WiFi direct.
The laptop sees the camera's WiFi signal but connects with "Limited Connectivity" when I input the camera's SSID and password.
What does Limited Connectivity mean and what should I check to enable a full connection so I can copy photos from the camera to PC via WiFi?

My girlfriend recently updated her computer from Windows 8 to 8.1 Since then, she's been unable to connect to her home wi-fi. She can only connect via cable. Unfortunately, neither of us have disks to roll her back to Windows 8.Yesterday she brought her computer to my house and it connected to my wi-fi with no problem.
I updated her adapter drivers to Windows 8.1 but that had no effect on her ability to connect to her home wi-fi network.Last night she ran "troubleshoot problems" and it says that her adapter is damaged. I highly doubt that since the computer is only a couple of months old and she could connect to my wi-fi network.
Computer: Lenovo G405
Modem/Router: ZTE ZXHN F660
Wi-Fi Adapter: Broadcom BCM4313 802.11b/g LP-PHY

For some reason my windows 8 Hp will not connect to my home wifi network. Has had no problem connecting in the past but yesterday I unplugged my router to move it to another part of my house and ever since then it can't connect. My cell phone and other laptop connect to the internet no problem.
On my Hp it will show a list of wifi networks and my home network is on the list, however, when I try to connect to it and then troubleshoot the problem it says I can't connect to the network because it is hidden. I don't see how thats possible since the network name shows up on the list of nearby wifi networks.
What I've done but hasn't worked:
Reset my router and laptop multiple times.
Tried to manually connect to network.
Forgot the network on my laptop and tried to reconnect.
I don't understand how one day it can connect to the wifi fine and then I unplug it and all of a sudden it can't connect but my other devices can.

I have Windows 8.1 installed on my laptop and following is the screen shot of the network information:
1. Basic Network information and setup information.
2. Properties of TIC/IP 4 connection under Advanced/WIN tab
Although, I can connect to other laptop if both are wired, but if other laptop is not wired then I can only see its name appearing in the homegroup connection but cannot connect to it.

I'm having trouble connecting my wifi printer (Canon pixma mg3100) and my Lacie Network Space on Windows 8, while I haven't experienced any problems connecting these same devices to my Win7 computers.
The driver for the printer is, according to Canon, compatible with windows 8.When I install the software on both my windows 7 laptops, it immediately recognize the network and after 5 minutes I can print wireless without any problems.
However when I try to install the same software on my Windows 8 computer it keeps asking to first plugin a usb cable and do a lot of manual steps, like pressing several buttons on the printer, it's ridiculous! After a while the software succeeds in finding my Wifi but it keeps on saying 'unable to connect'
My Windows 8 laptop is a brand new Dell Inspiron and I didn't change any network settings.

About two weeks ago I turned my laptop on and everything went blank, it couldn't read my drives, no data, nothing. After rebooting it a few times (with a lot of swearing and threatening to chuck it out of the window) eventually everything came back.
HOWEVER, since that night I have been unable to have a stable wireless connection. I have even reset my laptop to a factory setting. I then sent it away to get repaired and I'm still having the same issue. I've spent about two hours on the phone with my ISP but all of my other devices such as phone and iPad connect to the internet fine, although it does drop randomly every now and then.
I have a perfect connection when it is wired and works at a very good speed but if I try to connect to wifi it either says 'Unable to connect to this network' or 'limited' internet connection. My wifi also works to my ps3 and I'm able to stream videos without any annoying buffering.
The make is Lenovo and the model is Z580. It's about a year and a half old.
Is my wifi card (if there is one?!) broken? Can I just buy a USB port dongle that will connect to the internet? Or is there a magical cure?!

I am trying to troubleshoot a network connectivity issue for my Mom & Dad's laptop. It is an HP 64-bit running Windows 8.1. Up until this morning, it was able to connect to wi-fi. My mother was on the internet with no problems. They have my-fi with AT&T and my dad's laptop and tablet connect fine.
We have tried:
-Restarting the HP taking the battery out uninstalling the wi-fi network adapter
-Restarting and letting it reinstall for getting the network
-Manually adding the network back in
and nothing worked.
So, I took the laptop back to my house and connected it directly into my router via Ethernet cable, but to my surprise, it showed connected, but no internet connection. I ran the troubleshooter and it said that "Ethernet" doesn't have a valid IP config. I restarted the laptop with the ethernet plugged in, but it came back up with limited connectivity and the same error message. I tried connecting to my wifi at my house and again, it sees the various networks, but will not connect. I get a message when I hit the connect button that it is Checking network requirements, but then after about 30-45 seconds it says Can't connect to this network. All of the other laptops/pc's/tablets and phones are connecting just fine.

When i choose the connection's icon from the task bar, to connect to wifi, the connection side bar appears for a brief instant and disappears. At the moment i can connect to the network in my home, since it is default, but anywhere else i cant choose a new network.
Same occurs when i try to display available networks from the network and sharing centre.
I made a workaround which is very cumbersome for a casual user.
1. command prompt, and listed and deleted the profiles, using the netsh wlan command
2. Network and sharing
3. Setup new connection or network
4. Manually connect to a wireless network
5. typed the credentials of the network, checked start this connection automatically box and apply.

I purchased a new ASUS laptop a couple of days ago and have been trying to use the hotel wifi where I am staying to do the various updates and installs that new computers require. Unfortunately, while I can connect to my tethered cell phone, I cannot connect to the hotel.
I have another computer on hand that has no difficulties connecting to the hotel wifi, so I know the problem is in the new computer somewhere.
Network adapter is a Broadcom 802.11ac
Actions so far:
-Updated Windows 8.1 to current
-Attempted to reinstall drivers (uninstalling first) - Drivers are up to date and identical to the ones on manufacturer's site.

I'm going to throw my hat into the ring of people with wi-fi issues following an update to 8.1. on a brand new Alienware 17.
After the update to 8.1 last night, wi-fi will connect and then drop out after I start transferring data (browsing)
The only remedy is to either restart, or "forget" the connection and re-establish. At which point it will again only work for several minutes, or until I start "using" it.
Wireless adapter is a Broadcom BCM4352 Wireless adapter.

I decided to try a new network card due to problems with my onboard one, got a TP-Link TG-3269 after reading various reviews. most saying it installed in Win 7 with no problems or driver needed.Disabled onboard lan in bios, rebooted with new card in place, but card not recognised in device manager. Surprisingly, when I started windows troubleshooter it started working, it had reused my old onboard drivers even though it's in a PCI slot. but still not recognised in device manager.

Is there a way to setup network profiles or something so that when I bring my Surface Pro to work and connect to the wireless network there it will use the static ip address I have but when I disconnect and then connect to my home wifi it will go back to DHCP? On my MacBook Pro I can go into the network settings and change the location profile I have setup for networks but I don't see anything like this for Windows 8.

Recently I have been installed Windows Eight Pro 64-bit in two of my desktop computers. One pc having motherboard Intel DG41 and the other one is Asus Sabertooth P55i. I have two external Realtek NIC card installed in both of the pcs. When I was using Windows Seven 64-bit, I installed PPPOE as follows:
=> Conrtol Pannel
=> Network and Sharing Center
=> Setup a new connection or network
=> Connect to BROADBAND (PPPOE) [something like that]
But when I am trying to install pppoe on windows eight like the same process, it shows "Unable to install PPPOE" kinds of message and reboot. I thought the NIC card driver was not installed properly so I re-install the NIC card driver and again tried but it crashes and then reboot.
The funny part is, when I plugged the Ethernet cable into my built-in NIC card (the one that is embeded on Motherboard), it doesnt reboot and installed successfully. But I need to use the external NIC card and with that I am unable to connect to PPPOE.
I face the same problem in both of my pc and now I have to use the built-in NIC card. Is there any solution to use the external NIC??

I have an HP m6-k015dx and it has an intel centrino 2230 wifi card in it. I also have an old, netgear wna 1100 usb wireless adapter. The wireless usb adapter I have gets extremely better wifi connection that the internal adapter and the signal strength on the networks won't fluctuate. Are there any settings I can change on the intel adapter, or can I buy a new internal adapter to replace the intel to get better reception?

I'm having trouble keeping my lenovo laptop (running windows 8) connected to the internet. I have been able to connect successfully to multiple wireless networks and access the internet until I tried to connect to the new network.
Initially everything is OK - I can connect to the network and access the internet. However after a short period of time (anywhere from a few seconds to 20 minutes) the network connection will change to limited, without internet access. If I simply disconnect and reconnect to the network the internet will immediately be working again (at least for a few seconds/minutes).
Alternatively, if I run the troubleshooter, I always get the message that the default gateway is not available, which has been fixed by resetting the wi-fi adapter.

I'm using Windows 8.1 Professional. After the update to 8.1, I can't connect to my network printer which is connected to a Windows XP Home machine. Everything was working before the upgrade. I can currently see, connect, access and modify files on all the computers. I keep getting a message that I don't have permission to access the printer and I can't access the permissions on the Windows XP computer. I'm also using a Windows 7 computer which has no problem accessing the printer.
