Advent 5421 Wireless Disappeared
Apr 30, 2011
I have an Advent 5421 with Vista installed, it's nearly 3 years old and I have a few problems with it, but nothing too terrible, until yesterdy when I switched it on and found the wireless connection has mysteriously disappeared. When I try to connect it says there are no networks to connect to, which is obviously bollocks. The internet will now only work if I plug the cable in, which is no good as I share a flat with 2 other girls and if I do that, they lose their connection. I don't understand whats happened. I really am not computer literate at all, the only thing I tried was to make sure I had the latest software updates for my computer, which I did, but nothing happened.

Also I have updated the driver from Realtek, but the problem persits. I have also moved the hub to another location.The thing is that I have another Laptop which has no problem connecting.

I purchased an Advent DT2410 about a month ago from PC world. It came with Windows 8 OS a USB wireless stick and the following basic spec:
Intel® Core™ i5-3330 processor
Genuine Windows® 8
Memory: 8 GB
Hard drive: 2 TB
So initially brought it home, set it up and fired up connected to the internet perfectly fine with the stick. Then about once every 2/3 days, it would pick up no internet connection despite being next to the router and after 2-3 shut downs in a row would work again. When the connectivity icon was blank, I would go to trouble shoot it and windows 8 wouldn't do anything, not even attempt to detect the problems (bare in mind this PC is brand new).So I leave my home by my University and came back to my parents for Christmas. Lugged my PC back with me and set it up.So first I connected to the wireless no problems, loaded up my favorite forums and after image hovering over about 3 images the 4th would only load the top 3rd of the picture. Open up new tabs "Connecting" until:
A) Server would time out
B) Wireless would DC and then reconnect (before basically repeating the "3 image view")
C) Would work for a few hours (e.g. a streamed film) before screwing up again (rare)
So, reinstalled drivers, replaced the USB wireless stick (802.11n.) AND STILL problems problems problems. I then cleared the IP/TC stacks (I believe they're called) did it through the elevated command prompt and still nothing. So i'm using my sister's laptop to write this as my internet on my PC barely runs long enough for me to be able to check this page or download the program mentioned in the sticky.

I recently got a second hand Advent Roma 2000, which runs with Windows 7. After a while I managed to configure it to allow my T-Mobile internet dongle to connect. However, we recently got BT put in and I cannot find the wireless router [BT HomeHub 2.0].Now, at first I thought maybe the wireless detection on the router was faulty, but I checked my 360's wireless connection and that has connected with no problems.

I can usually figure stuff out for myself when it comes to computers, but to be honest I'm baffled. My HP 620 notebook wireless LAN has completely disappeared. I can no longer select anything to do with a wireless network, and it has also disappeared from the HP Wireless Assistant (which only has bluetooth on it - disabled by windows device manager?).
Anywho I did a quick internet search and it seems a pretty common problem with the HP series, and followed some advice they gave...
1) Did all the basic things (e.g. try and find a wireless network right click enable etc.)
2) Uninstalled/Reinstalled wireless assistant
3) Did some power off 30 second BIOS reset or something (literally have no idea what this is just followed advice)
4) I BELIEVE (note that this is way past my knowledge of computers) that I uninstalled the network adapter devices and reinstalled them on restart.
5) Finally I literally just took my laptop apart and took out, cleaned and replaced the wireless thingy
So all of this had no affect on my wireless LAN mysteriously disappearing. For those unfamiliar with the HP 620 it has a wireless on/off toggle button which is bright blue when working. Now however it is permanently orange and wireless has completely disappeared.

Ive just formatted both my hard drives and reinstalled win 7. Before this, my wireless connection was working just fine and after everything was complete with the win 7 installation a wireless connection cannot be detected. However, plugging an ethernet cable in allows me to access the internet just fine. I can also use the internet wireless'ly via my laptop, so its not a problem with my actual internet connection.After reinstalling I put my Gigabyte motherboard CD into the computer which ran some auto installations, one of which being a driver 'Realtek 8111/8168 LAN driver for gigabit (Win 7).' This didnt make any difference and I still could not access wireless internet. The list of component parts I got when I ordered my computer lists a '802.11N 300mbps PCI Wireless Network Card,' but no further info on make or model.

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

It all started when I wanted to add security to my wireless router (Linksys wireless-g 2.4ghz, 802.11g). Every time my IT guy tried to add the security, the tabs to enter the info would disappear. Since we'd been having trouble with this router for years, I bought a Linksys E4200 wireless-N router. He set it up, my son's laptop works beautifully (no he didn't do anything to his laptop except turn it on, and yes, I am sending this message via my son's laptop). Both of my laptops, however, are a mess. The IP address has disappeared (0.0.0.0), and after running all night, still cannot be found. My IT guy is absolutely baffled as to why this is happening. Before the router installation could be completed, he had to disable my Dell wireless network. He restarted it after the router connection was completed. Everything looks fine, but neither of my laptops will connect to the server, because THERE IS NO IP ADDRESS FOR EITHER OF THEM.

I have Windows 7. I was using my wireless network fine but all of a sudden it disappeared. I don't even see it in the list of available wireless networks, even though other networks are showing. I have to use the ethernet cable to connect to internet.

I have an Advent Laptop running vista and I have a problem with windows suddenly not being able to find one specific wifi network. I have no problem connecting to my home network, or that of any of my friends networks.However when I go to the holiday park where I have a caravan and go into the owners lounge to use the free wifi windows can't find it. (I used to be able to connect with no problem, it's just that for some reason windows can't find it now). Everybody else in the lounge can connect with no problem.If I use my phone's usb tethering feature I can connect to the wifi network. If go into another part of the complex I can connect to the wifi there with no problem.On the park they operate two networks, one in the owners lounge, the one I can no longer connect to, and one in the cafe/bar which I can connect to.I can only assume that some 'setting' on my laptop has changed and is stopping windows finding the network, but I have no idea what it could be.

I have a cable modem and it is attached to my computer, and it is also attached to a wireless router that we have been using for various wireless things around the house, like our phones and also the Roku box (for Netflix, etc).When I got the wireless router I was told to set up a private network and to use a password. I did this (though I don't remember how) and whenever a new device was first trying to access the wireless from the router it found the network name I gave, and I put the password in and used the wireless.
Last night we had some trouble watching something on Netflix using the Roku box and it connected to wireless but not to the local network. Then this morning it did not even find the wireless connection. I looked at my iphone and saw I had a strong wireless signal, but when I looked at the wireless settings it just said "linksys" (the wireless router) -- the network I had set up was gone!I looked on my PC in Control Panel, Network and Sharing, and the network I had set up and named does not pop up as one that's available.
However when I click on "Manage Wireless Networks" that wireless network I had set up is still listed there -- it's just not showing up. Somehow that got dis-associated with my router.how to re-establish the connection between the router and the network name/password I had established.

I'm trying to set up this 1130AG with a private wireless network and a guest wireless network. Initially it had just one wireless (private) and it worked fine, but then when I created the two VLANs for each SSID and then the guest SSID and now the guest SSID is visible/broadcasting, but the private SSID has disappeared or is off.
P.S. - It's a Cisco Aironet 1130AG (AIR-AP1131AG-A-K9) running 12.3(8)JEA system software and I'm using the web GUI (I'm not familar with the command line for Cisco products yet).

I am running an ASUS laptop with Windows 7. My wireless has been working fine, but my room is quite far from the router, so I bought a signal-booster USB aerial made by Realtek (REALTEK 11n USB Wireless LAN Driver and Utility). It came with a small software CD too which I installed, and it worked fine for two days and boosted my wireless signal.However (you knew it was coming, the story can't stay happy) soon the red light on the USB booster stopped blinking and it showed the red 'x' where my wifi connections are. I couldn't get it to re-establish a connection without doing a full system restore and re-installing the USB signal booster, which would then work again for a short amount of time (maybe a day, maybe an hour). And worse, now when the USB booster is unplugged from the computer my laptop will not return to recognising wireless connections like it did before I installed the USB signal booster. It simply does not find any connections - the only time it does is directly after I have re-installed the software from the small disc which came with the Realtek USB signal booster.
I have now uninstalled the Software and anything made by Realtek but still it is finding no connections.Now I would just like to find a way to get back to where I started when my computer was finding all wireless connections like normal... a connection with a weak signal is better than this nightmare of constantly restoring my computer just to get a brief connection

I upgraded the firmware on my newly acquired DAP-1522 from v1.02 to v1.21 (the hardware ver is A1). But weird thing happened after the upgrade--the Setup->wireless network settings portion of the set up menu disappeared! I re-flashed the upgrade once more and it's still not showing. Reboot the AP--same thing!

Since always, my wireless connection had two options, the AARON network, which I always used and dlink (unsecured) which I never used. While connected to the AARON network, it lost connection, and dissappeared from my list of available connections. Is there anyway to get it back?

I had a network connection to the main family computer that just completely disappeared after I got back on it. It had been on all day because it was defragmenting, but a few minutes after I got back on it (I had just sat down in the chair and sent a couple messages on a chat I was in and dismissed an "Oh, Windows Media player found another WMP on main computer! Wooo!" notification) and then it was gone.
I assumed the internet had crashed so I gave it a couple hours, no internet. I stayed up longer waiting, writing, playing some games, but nothing. I didn't check the Network computers thing until now.
Usually even when the internet crashes the main computer still shows up in the computer list but it was just mine then. It seems like it totally dropped the connection and it can't find it again when I try to create a new one. It's not like I watch p~rn or download anything I'm not supposed to download so...
And the network icon doesn't have a big red no connection at all x - It's just the two computers, no world icon, no x. I've tried booting in safe mode with networking, nothing, 'netsh winsock reset catalog' + 'netsh int ip reset.log, nothing, create new connection, nothing, and repair memory problems, nothing. : Microsoft Security Essentials found no viruses after a full scan, and it had been updated hours before the internet had a tantrum. I recently uninstalled Malwarebytes because according to a friend its update crashed her computer so I have no other virus scanner to use.
Oh, I'm runnning a Windows Vista Home Premium. Mine is genuine, it came with the computer, but my father had the bright idea to use -my- Vista disc to install it on the main PC, so it's all 'rawr not genuine' though as far as I know, my father's W7 laptop is still running just dandy.
We use a D'Link router, and it's worked fine until now. I don't actually know how my computer is connected, I'm pretty sure it's hardwired to the modem or router, but my father's is wireless. I've been searching like mad for the router's wireless USB thing, but it seems to have walked out the door.
