Wireless NIC Not Picking Up Available Networks Or Connections?

Aug 27, 2011

My laptop has suddenly stopped connecting wirelessly. Just fine with ethernet though. My Wireless adapter is enabled and showing fine in Device Manager and has the latest driver. Wireless Zero Configuration is enabled in services. I tried simply disabling and then re-enabling the wireless adapter but still no luck. I tried selecting the repair option for the wireless adapter and I get the exclamation in yellow triangle deal. I checked to see if I was having issues with firewall and that's not it either. When I click "View Available Wireless Networks" the dozen or so networks that use to appear are gone. I power cycled and reset my modem with no luck. I've also did an ipconfig /release and ipconfig /renew in CMD but nothing changed. I have not changed any wireless settings for my NIC or modem/router and don't understand what else I can do.

Cisco Firewall :: ASA 5505 - Setting Up 2 LAN Networks And 2 WAN Connections?

May 16, 2013

I have an ASA 5505 with Security Bundle license.
 
I am able to create 2 LAN networks (192.168.9.0 and 172.16.9.0) Vlan1 and Vlan12 respectively. I also setup 2 outside interfaces (outside1 and outside2).
 
Network 1 (192.168.9.0 - VLAN1) has no issues going out via Outside1, however I can't get Network 2 (172.16.9.0 - VLAN 12) to go thru outside2.
 
I put in a static route (route outside 172.16.9.0 255.255.255.0 x.x.x.x), the x.x.x.x is the default gateway of my ISP.

Wifi Cannot List The Networks Available

Dec 23, 2012

I am facing a problem since today as my WiFi is turned on, but i cannot view the list of networks that is available in my workplace. When i asked my colleague whether he could view the list in his laptop, he was able to. And also when i checked through my smart phone i was able to view a list of wireless networks. So it means there is some error in my laptop. I realised this when i tried creating a AD-HOC connection which eventually resulted in 'Windows cannot set up NETWORK NAME'. Why is it that i am not able to view the list of wireless network? And why can't i establish a AD-HOC connection?

Combining Ethernet And Wifi Networks

Dec 13, 2012

I'd like to know if there is some easy-ish way to combine wifi and ethernet in a network.Since a picture says a thousand words, here's what I want to achieve:I use the desktop computer as a file and media server using windows home group.I have the laptop running windows 7 connected to the TV.So far I've been using just wifi, but when I try to stream movies from my desktop to the laptop I get freezes and glitches.I can't connect both my desktop and laptop wired to the ADSL router, since it's behind a wall I'm not allowed to drill trough.I have a spare network switch and cables, so I was thinking I could connect the ethernet adapters on the desktop and laptop together trough the switch, I'm just not sure how to configure the computers.

M300 Wifi Stopped Detecting Networks

May 9, 2012

i own an THOSHIBA SATELITE M300 using WINDOWS 7 ULTIMATE SERVICE PACK 1 and recently my laptop has stopped finding any wireless networks. Other laptops connect via wireless to the hub without any problems so it must be a problem with my wireless card. Ive tried turning off my hub, as well as system restore and uninstalling my wireless device and letting my laptop reinstall it but it hasn't changed anything. my device manager says that my wireless card is working fine.Even i reinstalled the drivers.

Connect A Router To Multiple Wifi Networks?

Nov 19, 2012

My neighbor and I were wondering if it is possible to combine our respective internet connections in order to gain a faster connection overall. What would be ideal would to have a wireless router in one of our houses, that is simultaneously connected to both of our ADSL routers, and to which both of us are able to connect. Do I need a specific type of router?

No Wireless Networks Ar9285 Wifi Card?

Jan 26, 2012

I have read numerous postings on this and ather sites about the Atheros AR9285 not being able to see wireless networks - and guess what I have the same problem!My laptop is an HP CQ61-312SA upgraded to 4GB of ram, and running Windows 7 Home Premium, I have tried everything I can find on this and other forum sites with no luck at all, including updating drivers, making sure Wlan is started etc and I have downloaded programs like Xirrus Wi-Fi Inspector and Insider = both of which show absolutely nothing.I have one other problem that might indicate a software problem - on the odd occasion when my computer does try to connect to a wireless network it resets to a blue scree which states that it is doing a 'physical memorey dump' and then restarts.My Atheros card has worked perfectly for 2 years, but I managed to purchase another it case it was faulty - with the same results. I also upgraded the memory in case of a memory fault.Rolling back drivers and using system restore does not work and ipconfig/all gives identical readouts to others with this problem.

There are free vpn services. When the vpn adds a pad lock to the network icon, is it then secure to use it on insecure networks like public wifi to get internet access? I mean, the password is given to you from the vpn provider's website.

Wireless Usb Adapter Not Picking Up Any Wifi Networks

Oct 19, 2012

I took this wifi adapter from a pc that isn't being used, and decided to plug it into one that is. While it was in the other pc, it worked, now that it's in this pc it doesn't detect ANY wifi networks. I decided to plug it into a laptop and it worked the minute the drivers were installed.The problems are as follows:

* When plugged into the pc, the adapter's utility app just says "Checking status" and no info being displayed thereafter.
* Windows says the device is working, but it does not come up in the Internet Access popup window in the task bar.
* No info comes up in Xirrus except for the name of the adapter.

I installed both the drivers that came with the adapter, and the latest drivers from windows update. Neither worked.It is a Billion BiPAC 3011N adapter.

Combine Two Connections Wifi And Lan

Mar 2, 2012

What I want to do is combine a sad 1.5M DSL connection and a long range WiFi signal into a single connection for a rural area home.I am looking for any effective solution (including boosting WiFi output signal beyond FFC suggested values). The WiFi long range antenna (DISH + gutted LNB) receives a full bar 40+ Mbps signal from 11 miles away. DSL is standard 1.5M over DSL Modem.

Windows 8 Laptop Will Not Connect Or Identify Any Wifi Networks

Mar 28, 2013

I have tried restarting my laptop multiple times (something that usually works for me in terms of reconnecting to the internet) but that didn't work. And like i said it does not recognize a single wi-fi network while my ipod, phone, and the other computers in my household recognize our wi-fi and our usual neighbors wi-fi without any problem.I was torrentingsome music yesterday, and may or may not have stumbled across a bad site with a virus, but that's the only conclusion I could make.(Currently posting this on my brother's computer)I need to get my connection back and get online again asap?

Vaio Not Working On Certain Wifi Connections?

Sep 21, 2012

I bought my Sony Vaio notebook about 2 years ago and have since had problems connecting to certain networks. The laptop will connect to the network but when i open my web broswer it doesn't let me access any web pages. Basically there's no internet connection even though im getting a full strength wifi connection.

This problem only happens in certain locations. My parents house its fine (using a sky router), my old house in London fine (sky router again), my friends house (doesn't work), my new house (doesn't work - BT router), on the train (no again)

Its very frustrating, although it was manageable before as it worked in both my houses. However now it doesn't work in my new house its pretty much pointless me having the internet.

D-link Dir-615 :: Multiple Connections On Wifi

Nov 6, 2011

When I connect 2 laptops to my router, why does the speed/connection get split? I would understand that if the speed was maxed out or something but it's a lame 500 kb/s connection. Do all wify routers behave this way? It's kind of annoying since there's a trafic quota limit implemented and when someone downloads, the other one can't do s^&t? how to handle this?

Home Network :: How To Connect And Prioritize Different Networks To Wifi Route

Oct 11, 2012

I work in a small village in Africa and Interent access is often very unreliableTherefore I have 3 different ways of accessing the Interent from my home.The cheapest is Wifi from a local provider, but that doesn't always work. More expensive and still often unreliable is a 3G access. Then, when WiFi and 3G don't work I still can access the Internet via a Inmarsat BGAN satellite terminal, but that is very expensive.What I'd like do is to connect several computers to the same WiFi, 3G, BGAN Satellite Interent (all Ethernet) access via a home WiFi network.Now the questions I have:- can I just connect everything to a switch and then to the Wan-port of a wireless router?- how do the prioritisation works? When there is 3G available, I dont want to access the Internet via the BGAN, bacause that's too expensive?

Unable To Find Wifi Networks On Windows 7 Acer 3810t

May 9, 2011

I have an Acer 3810T laptop and am running Windows 7 on it.The problem I've had is my WiFi has been unstable. For example for 5 minutes or sometimes up to an hour I can easily find wifi networks in range of my laptop but then out of nowhere it disappears and I don't find any networks but any other WiFi device will find my router so I know it's laptop related.I did some research on Google and found out this is an issue others have had with Windows 7 and it seems to be something to do with when updates are installed. I followed the advice to remove my WiFi drivers and reinstall them so I downloaded a file for the Intel drivers from Acer's website. I went into Control Panel and removed 2 devices that were related to WiFi. I then did a scan for hardware and found one wifi device, an Intel WiFI Link 5100AGN. I installed the driver for this one. The problem is I know I removed two and this is the only one the scan found and I can't remember the name of the other wifi device/driver I removed.Unfortunately ever since I did this my WiFi isn't working. In the control panel it shows all drivers are installed and working but when I click on the bars at the bottom of my screen no wifi networks show. I have tried going into the Network and Sharing Center and for example I select set up a connection or network and when I select Manually Connect to a wireless network it states "An Unexpected Error Occured" so I know something is missing that's allowing the WiFI to work.

Linksys Wireless Adapters :: Wmp600n Does Not Find Any Wifi Networks

Jan 29, 2011

I've been having major issues with my wireless on this computer (randomly decides not to work while computers in the same room are fine) so I got a new wireless card to see what it could do. Installed it, everything says it's installed fine, but it will NOT detect any wireless networks. Not just mine, any of the 8+ networks I can usually detect from my room. I'm on Win7 Professional 64.
 
Things I've tried (and I'll be seriously annoyed if people reccomend doing them a 14th time, as I've already spent an hour on livechat with a support person telling me to do things I told her I'd already done):
 
Installed with 4 different drivers (the ones on the CD, the ones on the website, two versions directly from Ralink for the chipset) Tried both the manual and automatic "update driver" options in device manager. Uninstalled/reinstalled it like 4 times. Moved it to a new PCI slot.
 
Removed the old adapter before installing it. Removed the old adapter after installing it. Tried connecting to my network as a "hidden" network (which it's not). Installed only the driver and not the adapter utility, and used the utility. Installed the software before physically installing the adapter. Installed it after physically installing the adapter.
 
I'm at a loss. It doesn't detect ANY networks. No, it's not a problem with my network, there's more than a half dozen that my other adapter, in the same computer, can detect. And I don't know why. It has not ever worked properly. The antennae are on properly, nothing is interfering with it (though that would be odd since it's 3 inches from an adapter that can detect other networks). I might be willing to accept that it's just DoA, but that would be odd considering it installs just fine and reports that it's working just fine.

Tp-link Adapter - Cannot Connect To Wifi Although Connections Available

Dec 11, 2011

I have been using a TP-Link wifi adapter for last two months, It worked flawlessly till a couple of days ago. It just so happened that i turned on my computer and even though the wifi connections were available, when trying to connect this message keeps showing up " Windows was unable to connect to UoC WiFi". I have tried everything from making a new wifi connection to changing usb-ports

FYI I use the same wifi connection on my netbook and android, and they are working fine, so it's definitely not a problem with the ISP.

Voip Phone Stops Wifi Connections?

Feb 26, 2011

I have recently been experiencing a problem. This started to occur after I had gotten new internet service and a new router. I now have comcast, and a new NetGear router. I also have a VOIP phone connected to the router call "AllVoi". Now, whenever I use this phone, all connections on WiFi go down as I am using it. While, when I am using any ethernet connections dirctly from the router, it works fine. It becomes a large problem when you are watching a video or something from a laptop WiFi connection.

Build 1 Home Network Using 2 Wifi Connections?

Sep 7, 2012

setting up a single home network in my apartment that will be able to connect to and use 2 separate wifi internet connections to provide stability and reliable bandwidth for a home network.

Situation: I have recently moved into an apartment complex that has 2 separate wifi connections that are available to the residents free of charge. (yes i am authorized to use both) I do have the option of paying for and having my own personal DSL line installed but I would much rather use the free wifi and not have the monthly bill.

The Problem: My apartment is located far enough away from each of the routers (One wifi at each end of the building and I am in the middle) that my signal strength is poor most of the time and sometimes heavy traffic on one wifi requires that I disconnect and connect to the other. Wifi A is farther and has very low signal and low or no connectivity. Wifi B has good signal most of the time but gets very slow during peek usage times of the day.

I understand that I need one or more high gain antennas in order to receive adequate signals from either Wifi connection.

Between me and my son we have 2 laptop PCs, 1 Desktop PC, 1 network printer, 1 Xbox, 1 HDTV and my smartphone. I don't want to try to equip each device with its own high gain antenna and try to figure out which device should be connected to which Wifi depending on available signal and bandwidth. Rite now I do not have a Home network set up at all and we are only using 1 laptop and the Xbox and each is directly connected via wifi (usually to Wifi B).

If I could connect to either Wifi A or B with decent bandwidth and reliability and then be able to network or connect all my devices via wireless or wired to my own router/extender etc. I would be happy. However.. Given that I must share bandwidth with the other residents and at times one Wifi has heavy use while the other does not. I have been trying to research how to connect to both wifi signals for load balancing, reliability and hopefully greater bandwidth.

D-link Dir-655 :: Wifi Connections Dropped Periodically

Mar 5, 2011

My DIR-655 drops WiFi connections every few days.  All wired connections are fine.  Rebooting the router fixes the problem at that time.  Cable modem works perfectly fine. [code]

I'm sure I'm missing some devices, but that should give you the general mix of wired/wireless devices that I use.  I'm single with visits from my son every other weekend, so network traffic is not that high at my house.  I've had this router for a couple years now and didn't use to have this problem.  I've been updating the firmware, and I suspect this problem happened after on one those updates.  I just don't know which one.  Also, I didn't use to have any neighbors with Wireless Routers (that I could detect), but recently there have been 2 who have gotten them.  I was hoping this was a problem that D-Link was aware of, but that does not seem to be the case.  I would hate to have to go out and buy a new router (not D-Link).

Linksys Access Point :: Wet610n - Connecting Device To Certain Wifi Networks

Mar 4, 2013

I am having trouble connecting my device to certain WiFi networks. We work with hotels and we have a handful of devices that are just not able to connect to their network. Te device works fine in my office. When I get to the Setup page and do a site survey, it'll get to 100% and then display a "page can't be found" as oppose to showing me that it has been connected. We had the MAC address cleared in their network and still no luck. Firmware has also been updated.
