When I moved in to my roommate's house, her computer was already set up with an unsecured wireless network listed as Open and Disabled requiring no password. All of a sudden, it now has a lock next to the name in the list of wireless networks and asks me for a password when I try to connect. My roommate knows NOTHING about computers and has no idea how it happened. She has an Arris modem, Windows 7. I tried typing in the common IP address for Arris and I did get to a screen giving a lot of info about the system. But there was no where to log in or change any passwords.

I booted into Windows 7 today after not using it for a while, and I saw "some network drives were unavailable" in the corner of my screen. I disconnected the drives, and used map network drive to add a new one. It sees the server, but when I get to "Enter Network Password" every username/password combination results in "Logon failure: Unknown user name or bad password." There are only 2 user names and passwords that are used on my various computers in the house, and no combination of them worked. What's really strange is that the mac server is set for everyone to have read and write privileges.

I use a laptop and recently the wifi has stopped working for me. I can still connect completely but it says with "limited access," which results in me being unable to access the internet at all. The rest of the computers in the house work fine on the wifi and I double-checked the securtiy settings (WAP2 and all that) and it seems fine. What can I do? Tethering to my phone allows me to get on the internet and the computer connects successfully, but no websites will load whatsoever.

Bought an Acer Aspire One 522 netbook 3 days ago. It's got Windows 7 Starter installed as an OS. Had no problem connecting to my home network via wireless router, but yesterday all of a sudden it stopped working. Ever since my home network no longer shows up in the "Wireless Network Connections" list at the bottom right of the taskbar. I have 2 flatmates they both have no problem connecting and my iphone 4 also finds and connects without a problem. Also I can connect via LAN cable without a problem (hence me being able to type this..) It shows all other available networks but just not the one I need.. Very strange.2. Reinstalling device driver for Broadcom802.11 Network Adapter3. Deleting saved internet wireless profile4. Entering the wireless profile manually

I'm a an old disabled guy who uses a hand-me-down Dell Insprion 1150 laptop running Windows XP from bed (where I spend the better part of my days these days) connected via a Microsoft Windows Network to a couple of old hand-me-down PCs in the kitchen, one running Win 2K and the other running XP.The network worked fine for a while, but then I started having problems with the PC running XP. Now when I'm working from the laptop in bed, and click on an icon representing a drive or folder or file on the PC running XP, it takes 30 seconds or longer to make the connection. And all during that time the mouse pointer on the laptop has turned into that danged hourglass. My connection to the PC running Win 2K works fine. Also, at the same time this network slowdown with the XP PC started occurring, that same PC running XP starting stalling or freezing or hanging up on shutdown. So I'm wondering if these two problems are related.

I have a print shop that runs several computers on one network off of a single adapter. Last week the boss and I went out of town for some off site training leaving a single employee in charge of holding down the fort. When we came back we ran into a whole slew of problems not the least of which being that one of our graphics computers doesn't seem to want to recognize the work network anymore. It seems like the employee who we left (who, of course, "didn't touch anything") must have disconnected the computer from the network and started a new one as it is connected to one simply entitled "network". The issue I'm running into now is that when I check the network list the work network is not showing up at all. I've checked and I can ping the other computers on that network, they are all connected to the same network adapter, I just can't seem to get this one computer onto the preexisting work network.

I have an ADSL connection through Canal Digitaal, which I believe uses the KPN network. My Zyxel 2601 modem/router is usually accessed at 192.168.1.254. The following devices are connected to it: two iphones, a Macbook Air, an Apple TV 3 and a Mac Pro.all devices except the Mac Pro. Looking closer I found in their respective settings that they connect to 192.168. 2.254. All have somehow been assigned IP addresses on the 192.168.2.xxx network. The Mac Pro remains on the 192.168.1.xxx network.Going to 192.168.2.254 launches a login page for a KPN router called Arcadyan ARV7519 which is on ANOTHER SSID than my wifi network. Nevertheless, all my devices say they are connected to my network SSID but with IP addresses in the 192.168.2.xxx range.Does it have to to with the channels used by the respective routers or is there some phishing or such going on? What can I do to ensure that my devices stay on my Zyxel network?Weirdly, the SSID of the Arcadyan router doesn't normally show up in my list of nearby networks. It only shows sometimes.Also - in case it is relevant - when I try to access 192.168.1.254 from my Mac Pro I am able to log in, meaning I reach the welcome page of my Zyxel router though it takes a very long time for it to load.

I have a laptop which has always connected to this wireless network fine until yesterday. The wireless network seemed to suddenly just disappear. There are three other laptops in the house which can still detect that wireless network and connect to it except that one now. I have restarted that laptop and the network reappeared and it connected. But when it was restarted again, the network showed just for a minute or so and the laptop cannot connect and then the network disappears. I've restarted it many times now and it just shows the network for a brief moment, trys to connect and then the network disappearsThis is the info for the laptop:ech Support Guy System Info Utility version 1.0.0.2OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 32 bitProcessor: Intel(R) Pentium(R) CPU P6100 @ 2.00GHz, x64 Family 6 Model 37 Stepping 5Processor Count: 2RAM: 2998 MbGraphics Card: Intel(R) HD Graphics, 1275 MbHard Drives: C: Total - 293422 MB, Free - 248128 MB;Motherboard: TOSHIBA, Portable PCAntivirus: Trend Micro Titanium Maximum Security, Updated: Yes, On-Demand Scanner: Enabled

my primary source of internet at my house for the passed year is an at&t 3g usb modem (sierra wireless lightning), becuase i live in the middle of nowhere (only other option is satellite). Up until now i've been using a wireless ad hoc network to share the connection with multiple computers. I just purchased a cradlepoint router that is compatible with my usb modem so I can have a "real" wireless network in my house. I set it up yesterday and so far its working great, I have a wii streaming netflix, an android tablet, an iphone and two laptops (running vista, and win7 respectively) currently connected. The problem is my 3rd laptop, also win7. It is my primary computer that I use for business and absolutely essential that its connected to the internet. It (seems) to connect to the wireless network just fine, but gives me a "no internet access" error.
This laptop will connect to other wireless networks: it always connected to the ad-hoc, it will connect to my wifi at work and the network at my boyfriends house, also i just tried it with the verizon 3g mobile hotspot app on my droid and it connected right away. It also works just fine with a wired connection to this router (ethernet). I'm not sure where to start since every other device in my house is working with this network and this laptop will connect to other wireless networks.
ps/ Going through the windows onscreen troubleshooter it will either tell me "there is a problem with your broadband modem" or "There is a problem communicating with DNS server" (but it wont fix it)... and after going through endless google searches, i've done everything thats been suggested so far (making sure dhcp is enabled, powercycling the router/modem, updating drivers, ipconfig release/renew, disabling the firewall).

I had an issue with my Win 7 networking on LAN but no problem on wifi. When I plug in the network cable, it takes very long time to detect, and when it does, it shows Unidentified Network - No Internet Access and stays as public network. I do not have the normal options to choose Home, Work or Public Network. This happen at my work place. But my colleagues which on Win 7 have no issue. I tried to uninstall the anti-virus, disable the window firewall, but still fails to detect. There are few LAN port at my work place but it produce the same issue, very, very slow to detect.

Every time I connect it it will display "window cannot connect to (name of the network)" I don't know what happened. When I use my phone turning on WiFi, it was able to connect to that wireless network and get internet. I checked my network work adapter and it was up to date.I even reset the laptop to factory settings and it still display "window cannot connect to (name of the network)" when i try to connectDetails are the router is a Cisco linksys E1000 router which the network is W2psk-psk. I cannot change or reset the router setting because I am not the admin where i do not know the password to.[CODE]

This is my network topology. Sometimes it just suddenly loses conenctivity or traffic for unknown reasons, like the internet hangs for much time or maybe some routers just stop responding, even restarting ! Do you think there should be a Multi-WAN router that could take 4 WAN lines and give one LAN to plug at a switch for a better performance ?I know that my setup is wrong, give me your opinion about it and how to fix it .

I am running a VPN server on my desktop at home, with all the default settings, and i checked the box that allows clients to connect over the internet. this is win7 x64 computer. I opened up port 1723 with PPTP protocol on my E4200 router.On the client i am running win7 x64 as well. I am able to connect to the vpn, from another internet connection, but there is no local network acess. It says the status is No Internet Access. and the IP that is assigned is the 169.x.x.x one that windows defaults when it doesnt find a dhcp server.How can i get the client to connect with full local network access. Right now being connected to the vpn, it means nothing, i have no access other than being "connected".

I recently had my Internet disconnected, and decided to share my iPhone's Internet connection (tether) with my PC. Now, the iPhone connection works, but for some reason my PC prefers to use my original Internet connection thus no connection. The only way I can access the Internet is by going into adapter settings and disabling my router, but I do not want to do this as I have other computers on the network and I often share files.

It is a Satelite 733. Have pinged without any response however the wifi or hardwire will show connected to the local net.I have four other units surfing the web fine and wifi picks up ok except for one unit that my neighbor need will not connect no matter what. Have updated all the drivers, uninstalled and re-installed devices, reset ip, dumped the dns several times, etc.So here is the ipconfig stuff....ignore the cable connect I only have the wifi on at the moment. I have stared at this to the point where I know naathing .Is the tunnel adaptor the indication that the card is out? Oh and I tried taking out IPV 4 on both channels and nothing so I left one with 4 on and the other with it off just as something else to try. [code]

I have two Windows7 machines (PC and laptop). I've set PC as VPN server and laptop as VPN client using default built-in W7 network tools. I've disabled use default gateway in remote network on client machine, so client don't try to route all communication through VPN. I've routed port 1723 (TCP/UDP) on NAT to my server and enabled IPSec/PPTP/L2TP passthrough
I've put my laptop in indepedent network (basically I've connected it via 3G network), connected to VPN server and checked ipconfig /all
I've get:
IP Address: 192.168.1.101
Mask: 255.255.255.255
Gateway: (none)
LAN mask in server LAN network is 255.255.255.0 - I am surely missing something obvious, but Google doesn't give me any good advices; How can I access local LAN network from remote VPN client? How can I access local shared documents?

Dell Inspiron 1520 Windows XP SP 3?My Dell suddenly will not connect to access point / wireless router / DSL. Other computer in house connects fine. Computer is auto-updated by Windows, McAfee, Secunia, and frequently checked with System Mechanic, McAfee, Lavasoft, MalwareBytes. One of the auto updates may have been interrrupted.Says Wireless adapter "not present"...Does not recognize wireless in the area. Try to "repair" adapter, but message says adapter not present.I then use System Restore to 4 day earlier date and laptop connects immediately. I see a new symbol "Local Area connection on Actiontec m1000 has been added in the Network Connection window, and the Wireless Network Connection says it is connected to the correct network that has worked fine for several years.I have several Windows updates for the Malware Tool that install immediately if I reboot, but then I cannot connect to the network and have to use System Restore (which is taking longer and longer to restore...appx 1.5 hrs now).

My wireless internet connection on my laptop. The connection seems to work fine on other laptops in the flat. It works on mine too. Then after a short time the internet connection fails and the laptop says it's unable to connect to preffered wireless network, and unable to detect any wireless networks (usually there are others around too).The amount of time before this happens seems to be getting less. I have cheched that the radio switch on the side of the laptop is on.

My laptop simply decided to stop connecting to my wireless network.I'm at a loss as to why and what to do. All other devices in my house are getting a perfect signal from the network but my computer either can't find it, or only has 1 green bar and says it cannot connect. I've tried a system restore, I've tried to troubleshoot on my computer and can't figure it out. The weird thing is it is picking up other wireless signals fine (like my neighbors, ect) but just not my home one. Again, it was working one minute, then simply stopped working and hasn't been able to connect at all.

My computer is running on Windows 7. It has had no prior internet connection problems. It is wired to my DV-2020 router. My internet suddenly disappeared, as in, it doesn't work anymore. I'm not sure as to when it disappeared due to my personal absence, but from what I heard it was either during 'starting a game' or 'installing firefox add-ons updates'. Internet does work on other computers sharing the same internet (wired and wireless). On the computer that does not have access to internet it gives a "local area connection - No Network Access" and "local area connection - unidentified network." So far I've tried:
A system restore.
Restarting the router (at home as well as the provider)
Changing wiring.
Disabling / Enabling.
Disabling virusscanner.

My windows 7 computer was connected to my home's wireless network yesterday perfectly normally. I drove last night to my mother's house and proceeded to connect to her own wifi router wirelessly. Although my sister's computer that's on windows 7 connects ably, and both our iPhones connect, my computer will not. My computer finds the network( it is unsecured without a password if that makes a difference ) connects, receives an ipv4 address in ipconfig, yet does not obtain Internet access. It labels the network as an "unidentified network".
