Screen Blinks Then In A Few Moments Wireless Connection Fails?
Oct 26, 2011
I'm running Windows 7. As stated in the title, once I see the screen blink, I know I have a few moments of connectivity left. The screen will continue to blink, then the wireless network connection icon goes red with an "x" through it. The computer continues to work (albeit with the screen blinking), but with no connection to the Internet. Checking Device Manager indicates no conflicts. Manually pressing the "wireless connectivity button" on this Compaq, which shows green=connected, only turns it red for a second, then back to green as if the adapter is enabled. Doing this prior to the blink-failure cuts the wireless connection as it should. I added iTunes about a month ago, the problem started about two weeks ago.

Ok so I have a Netgear dg834gb v2 and I have a disconnecting problem on a wireless connection for my laptop. When I am using my laptop, my connection will drop at random moments mostly when I'm playing League of Legends. If I'm not playing it rarely disconnects. It drops for about 10 seconds and comes back up usually, but sometimes I have to reset the router. It only recently started happening and I have no idea why. Maybe it can't handle when I'm playing?

I have set this "Black Friday" printer up and it shows it is transmitting wireless. However, I cannot get my PC to find it! I have tried everything I know. I am not an expert but is there something in my Verizon router that might be preventing it? I don't know what else it could be but maybe there is an expert out there that can.

I have a Cisco ASA and have a client that has a NetScreen 5200 and we are seeing issues on the ASA that show the error [code] We have removed the repaly command form the ASA and wew are still having the issue. The other issue we see when this happens is that we see Fin,Ack sent from both the Rmote End to the Local End as well as from the Local End to the Remote End but it seems that they never arrive either way and then both hosts are sending RST, ACK.

When I start my laptop, an Acer 7715Z, it will try to connect to the internet, but often fails.I then try it a few times manually. But the first 5 minutes I can try as often as I like but it will give a 'problem' popup, offering me a windows troubleshooter (which doesn't find the problem).I just have to try manually over and over again until it finally connects.Then my problems are over and I can internet without loosing connection. This doesn't only happen at home, but also when I'm at relatives. So my modem or ISP is not the problem. Also, my other equipment works just fine (mac, iphone, ipod, netbook).I've updated the Broadcom 802.11n adapter driver, run a virus/malware check, etc. but nothing works.The wireless lan adapter I assume basically works ok as it doesn't loose connection once I get online? Is there another setting I could check or optimise? I find it so strange. It's like the first 20-30 times trying to manually connect something is blocking it and once I get through I'm online without problems or losing connection. As I mentioned earlier, my other equipment go online almost immediately. Is there some windows setting that could block my manual attempts for a few times before letting me in? Could the broadcom adapter be faulty after all, even when after connecting it stays connected and problem free? Any control panel or other setting I could check first before sending it to be checked/repaired?

I have a E4200 V1 with firmware 1.0.0.5 installed The problem is that when I connect the cable from my modem to my router and recycle both I get a rapidly fashing Cisco light and can not connect to the internet.If I remove that cable and recycle the router my network works but (obviously) I have no internet connectivity.This was working (almost 2 years) without issue until today.I updated the firmware and did a factory reset and neither resolved the issue.My next experiment is to see if I can't get log files (since the factory reset) but I can't do that at this time.

I purchased and installed the above router to replace a working router that had a problem with our new condo location. The old router couldn't access one of our computers. The EA 3500 worked seamlessly for 6 months. Now the connection fails intermittently (more times off than on) from that one computer. It is two rooms over from the router & modem. These are now in a fixed location that cannot be moved.

I have a D-LINK 601 router which has been working fine. I was told by a friend that it is not password protected. I think that I have set it up now with an adm password. The router and the DSL modem is still connected as before, but the Internet LED blinks orange.

I purchased two WUSB600N V2 wireless adapters recently and have had nothing but problems on an otherwise stable network where I have iPads, iPhones, Netbooks, media centres, wireless printers, Notebooks and other USB PC-based network devices working without problems.
The WUSB600Ns are connected to desktop PCs, running WIndows XP SP3. I have removed the Linksys Network Management software and use Microsoft's wireless network management software. I am running the latest drivers 1.4.10.0 for the cards. My WAP is a Belkin F5D-8236-4 running in WAP only mode. It is set to 40Mhz Channel 11 primary, Channel 7 secondary. Protected Mode is off, Broadcast SSID is on. I run WPA2-PSK AES for encryption. Note: I've tried all combinations of bandwidth and channel settings. I've run Netstumbler to find clear air channels - 11 seems best.
The issues are:
* seldomly connects at boot automatically without intervention.
* occasionally does not find WAP to connect to.
* sometimes will not connect to WAP - sits at "Acquiring Network Address".
* sometimes will not even get to Acquiring Network Address.
* Will often, once connected, after a while lose connection - the timeframe is inconsistent.
All of my other devices do not have these issues. I've been working on this issue for about a week trying to stabilise, even get a consistent failure pattern, but I'm about to send them both back.These are close to the most frustrating devices I've configured and I've got a lot of stuff on my network.

If i try to ssh to a 3750 switch on our 4th floor, it ask's me for a username and password.
After entering the password, it doesnt connect. It shows a blank screen with a flashing cursor.
If i connect to the switch directly via console port, i can see port uplink and downlinks but still cant do anything more.

I have an older rev a DIR-655 that has served me well. Today I finally upgraded my ISP to cable (from a slower DLS connection) to get reasonable speed/price All is working very well but unlike my old DSL modem the internet status light on the DIR-655 blinks very rapidly all the time instead of when traffic is passed.The new modem is a Motorola SB6141,I am running the latest firmware 1.35NA I went through a complete re-setup to see if that would calm the light but no dice there. (the settings arrived at were basically the same for the old Sprint modem) ,Is there something I am missing or is it time to retire the old DIR-655 for something more current.

I cant get this damn thing to connect to the internet (att dsl modem). I have ran the installation cd mulitple times and also configured it using the http. If i reset it while everything is hooked up and it makes an internet connection using DCHP (I think its called), but i need a PPPoE connection.
It seems to change my password (the username one that access the modem). The way i know is it always has more characters that the one i was provided by my isp with (*****). I dont enter any information other than my username or password (IP is dynamic).
I have a westell F90-6100 as my modem.

problem with my Dell Latitude D600 Laptop,I tried re-installing my OS, so now with a fresh new OS the wireless capabilities worked fine, but only for the first day, then the next morning the whole problem began again. Now it would say " No supported wireless adapters found" and when i would open the device manager some devices would have the yellow exclamation point, some of the devices would say "Intel PCIC compatible PCMICA controller" and " PCMICA MTD-0002" or just "card bus controller" and many other ones that would alternate when they appear. And also sometimes my network adapters would completely disappear from the list. I also tried scanning my whole drive for viruses and nothing was found.
Then i found that if you disconnect the wireless adapter physically and re connect it, it might work, but it didn't. I should also add that before this problem for some time i had another problem with the same laptop that had to do with the battery malfunctioning, and it displays a 4 orange , 1 green pattern sequence on the LED charge display. But it had never affected any of the laptops hardware or software before, so I don't know if that might have anything to do with it.

I've got trouble using PPTP connections with the RV220W small business router.When trying to connect to the router of a branch office with the Windows PPTP client (i.e. on Windows 7) from outside the companies network first everything seems to be in working order (user name and password are checked, the device is registered in the remote subnet) but then a window pops up saying there has been an error connecting.
Here is some information on my setup:RV220W with firmware 1.0.3.5It connects to the Internet using PPPoE dialindyndns account configured and workingAnother router working in "Act as a DSL modem" mode is used as a modem (AVM FRITZ!Box 7170)The RV220W is maintaining a IPSec tunnel to a main office, which is working finethere are 2 local VLANs (one with access to VPN tunnel, one without), each with a own subnet (192.168.201.0/24 and 192.168.202.0/24)PPTP users are on a seperate subnet (192.168.203.101 - 192.168.203.111) My first guess was, that the intermediate router acting as the modem could be a problem, but i verified all settings on that router and it should not filter anything. After all port forwardings, the IPSec tunnel and so on are working.

I can't seem to skype or video chat of any sort (ie: aim video chat, facebook video chat, etc.) on my computer. Whenever I start skype or try to start a video chat on aim/facebook, it fails and my internet disconnects for everyone. I don't know what could be wrong. Using the same wireless internet, my friends are able to video chat on their macbooks. It seems like my computer is the only one that can't video chat. Video chatting works when I use a sprint internet card. I have a sony vaio laptop running on windows 7. Our router in our apartment at school is a D-link wireless N? In addition to this problem, my internet loves to disconnect randomly too...this problem also persists at home with my Cisco Linksys router (model WRT160N V3) and Speedstream 5100 modem.

i'm having problems connecting to my RV220W using PPTP. The first time I set up PPTP on the box, everything worked just fine. Now, however, PPTP just won't work. No matter how I try to tweak various settings on the router, the connection fails. I have tried connecting with Windows 7, Android and OSX with no success.The router came with version 1.0.1.0, and I have tried downgrading to 1.0.0.26 and upgrading to 1.0.3.5, but alas, I can't seem to make PPTP work again.

I have a CISCO RV 120W router. I have set it up with a static IP address from Verizon. Internet can be accessed.I just want IPSec passthrough for some people who can connect with Nortel contivity client to the company RSA server. I can make only one connection. The second connection fails with 'banner text' response issues. One connection always works. The router has the latest firmware. I have enabled IPsec passthru.

we are using Cisco VPN client to access our corporate network.I have 5 new notebooks Dell Latitude E6410 OS Windows 7 Professional x64, with identical hardware configuration.I downloaded Cisco VPN Client 5.0.07.440 (64 bit) and installed it on all notebooks. It works fine on 3 notebooks, while on 2 notebooks the VPN connection fails with error:
Secure VPN collection terminated locally by the client.
Reason 403: Unable to contact the security gateway
We use a smartcard for VPN access (etoken from Aladdin)
Here an extract from Cisco log:

It seems the problem is in the certificate, but I verified and Cisco client says it's ok. It's also the only valid certificate in MMC->Certificates->Personal.Furthermore, also using other smartcard (etokens) of other users it doesn't work.

Why should I need a router with a touch screen? Just because, its fancy or just because its bringing a new trend to wireless networking? I wanted to buy the D-link DIR 865 but it became vaporware. Now this came up Almond of Securifi. Dong Ngo of CNet has reviewed it. Does it really make sense to buy a wireless touch screen router, leaving the old trend of traditional routers with web interface?

I've just discovered that my wireless router is not secure (WRT54GS v5). In trying to set up the propoer security, the set up screen appears as incomplete (after entering 192.168.1.1). It only shows 3 tabs at the top - Basic Setup, MAC Address Clone, and Advanced Routing. No tab to deal with the settings. I have tried resetting the router and plug/unplug several times. Triued entering thru IE and Firefox.Is there another way to set up the security on my router or at least get the proper screen?
