D-Link DIR-655 :: Wireless Network Keeps Crashing

Nov 10, 2011

We purchased this router 6 months ago. It has been working perfectly fine with no issues whatsoever up until two days ago when suddenly our wireless network disappeared from the available networks. We have all the updated firmware. Originally we tried setting up a new network, that worked for about 20 hours before the network crashed again. Once it had crashed that time, I was just planning to wait it out until my husband got home so he could assist me with it but before he arrived him the network mysteriously reappeared. That night it once again disappeared. The following morning it was still lost, so I reset the router to the factory settings using the button on the back, and once my computer detected it router again I once again set up a new network. That worked and my connection was fine for about 12 hours this time before it once again crashed. I brought my laptop to connect it to the internet via the cable, and after when I disconnected it to leave the room the wireless was back up again.

D-Link DIR-655 :: Network Crashing After Adding Kindle Fire To The Mix?

Feb 11, 2012

I just acquired a Kindle Fire for my wife.  Joined my Dir-655 network just fine.  I have never done a firmware update (using 1.10) and have lived by the "if it ain't broke. " axiom.  Dell laptops, Mac laptops and desktops, Wii, X-box, LG Cinema TV, Roku, iPad, multiple iPhones and iPods all connect and work fine (with the occasional (once a month) reboot of the router necessary). Using cable modem (bridge mode), no historic issues.  Suddenly when the Kindle Fire is utilizing the network at the same time as one or two other devices, the network crashes, and a power down reboot is necessary.  A Google search reveals a fair number of complaints about this across router brands.

D-Link DIR-655 :: Keeps Crashing Once A Day

Mar 20, 2011

I just registered the DIR-655. I saw it was on sale on Newegg for around $50 w/ a $15 promotional code. I decided to purchase that, and I have had it for the past 4 days. Firmware is Version 1.32NA. Hardware version A4.Unfortunately, it has been crashing once a day (I noticed it usually crashes between a window of 4:30pm and 6:30pm if that makes any difference). What happens is that it starts to slow down my entire net. That lasts for about 5-10 minutes before my entire net crashes to the point that I can't even access my router. I have to restart the router and cable modem afterwards..

Today, after the crash, I decided to connect my own primary computer straight to the cable modem. Internet started to work while connected straight to cable modem, but it was pretty slow. I did not run a speed-test so I don't know the exact speeds it was getting.Here's how my network is setup. Before I get to it, I want to say that it is a bit messy. I am removing one of the routers (the Ativa one). Goes like this:

Network Crashing At Random Point?

Jun 20, 2012

My router keeps crashing like it is restarting. it turns off then all the lights are beginning to turn un again after some time it repeats again and again....Last thing they did was turning down the internet speed for our Network. It worked in some time but then it begun crashing again...Then they said it was the cable in the road that could not take all the data stream... And something about and Bit error?I just dont belive the cable in the road thing because our neighbour are running 10 M/bits without a single error anytime... I am not an expert but i've found out that we are running a Sagembox or something like that. The hardware version (if that is important) is: 3DK04-02 Everybody in the house is running Win7 SP.1. If you need any more information then i will try to find them.

Linksys WRT54G - Network Keeps Crashing / Disconnecting

Mar 15, 2012

I am on the internet, let's say browsing youtube, or play multiplayer games, sometimes my internet will crash and disconnect me, leaving that familiar yellow triangle with an exclamation mark. and that will stay there for about 1-5 minutes and then will reconnect me in. but sometimes it will just keep doing that repeatedly.I've tried to work it out myself, power cycling and everything but nothing seem to work.

This issue is on my laptop, and I am using wireless connectivity

-My isp is AOL (as long as I know) I live in Quebec and my broadband is from bell, well I think it's DSL or Cable, it uses the phone cable..

-My router is a linksys WRT54G and Modem is Speedstream 4200 ethernet/usb ASDL modem.

-I use AVG9, Malwarebytes. I am intending to switch anti-virus software but do not know which one is the best.

I am using a Belkin Surf wireless modem/router with this computer (Vista) no problems at all.When I boot up my HTPC (Windows 7) all is fine until it tries to connect with the Belkin Surf. Then its Blue Screen of Death and no joy. If I turn off the modem, the HTPC boots up perfectly normally. Turn the modem on and as soon as I try to recognise the home network, it crashes again.

Dec 19, 2012

no changes except switched out old steady wrt45g router cabled to different computer for a new (crazy good price) asus n66 dark knight.  stable old system after clean install xpsp3 several years ago.  abruptly started crashing and endless rebooting any time wusb54g attached.  no antivirus active.   never had linksys monitor software installed.  xp had handled everything well till now.  repeated  attempts to re-install drivers (rt25000usb) fail. occasionally xp sees "new hardware" and occasionally it simply immediately crashes.   attempted install of ?failing? usb54gv4 onto much newer W7 machine to try to test hardware w/o success.  linksys AE1000 usb adapter worked on W7 machine and also installed successfully on the old steady XP machine in question.

Linksys Wireless Router :: WRT120N - Low Speeds And Intermittent Crashing

Mar 30, 2011

I have a WRT120N router set up with WPA2 security and set to channel 11. Everything is connected via the router (one wired computer, up to a max of 5 laptops but just 2-3 on a regular basis, a wired xbox360, wireless wii and a few cell phones occasionally connect wirelessly). Everything has been working great, been getting at or very close to the 6mbps we are supposed to be getting...until the past 2 weeks. Suddenly the connection drops repeatedly throughout the night. It either shows local only or just "limited connectivity". Normally when this happens my laptop will pick the signal back up when things are normal but I am actually having to disconnect and reconnect for it to work again. It happens again in about 30 min to an hour after that. Also, our connection speeds are showing at .5 - 1.5 instead of 6. I plugged the cable modem (the 660 series sent out by sprint/embarq/century link (or whatever name they are going by today lol) into the computer directly and got 5.7mbps. I have tried power cycles of both pieces of equipment but that doesnt work.

Linksys Wireless Router :: E1200 - Download Speed Crashing

I bought a E1200 and have it hooked up to my Comcast internet.. When I have my computer hooked up directly to the modem I get a 30mbps download speed. When I connect it to my router the download speed crashes to about .5-.75mbps.. My upload stays pretty stable at around 6-7mbps.

My TWCable Keeps Crashing

Jul 27, 2012

I got myself TimeWarner Cable, rated at around 15/1 mbps. The guy came and just connected the line from my place, ran it all around my room and plugged it into a Motorola SB5100 Modem. My AV is ESETNOD32 version 5.

My problem is as follows: Before yesterday, I had DSL (1mbps) and it never crashed on me. No matter what website I went to, the connection was stable. The DSL modem had wireless and it was 100% stable too. Here I have a (new?) cable modem that gives me a connection 15x faster but it crashes so often! When the guy set it up, he told me to get speedtests, so I ran on speedtest.net and speakeasy to get them. The sites loaded and my internet was fine. But today, whenever I try to get to those sites, my internet crashes immediately. Not only that, but I notice that when streaming HD on Youtube or elsewhere, the connection tends to crash sometime afterwards. Additionally, the connection may sometimes just crash randomly while I do just about anything.

Cisco Switches :: SG300-10MP Keeps Crashing?

Sep 4, 2012

We are in an organization of 80 users with 5 Sx300 series switches with the latest firmware ( The network is mostly flat with all switches feeding into a Cisco ASA5505 acing as the primary gateway for Internet Access. Only our two 48 port POE switches have an additional vlan configured for the VoIP phones. We have one SG300-10MP that is powering 5 Cisco Aironet 1024N's that keeps crashing. A couple weeks ago it went down twice in one day. I updated the firmware and it did not have any hiccups unitl today. This issue has been consistent since we installed the switch in April. Originally the issue seemed to be caused by too much bonjour traffic causing a buffer overflow (we have over 100 Apple products). Since I updated the switch I have not seen any bonjour buffer overflow errors. Instead I get the following error when it crashes:

Internet Connection Via Ethernet Card Constantly Crashing

Oct 13, 2012

As of around a week ago, I've been experiencing a strange thing with my internet connection. I live in apartments that provide internet to everyone that lives there, and had been living here for a few months before this started happening.I now constantly have my internet crashing in the middle of browsing/gaming. I will either open up my laptop to the internet not working already, or it will work, but crash randomly while I am using it.

Trying to load a page on google chrome, it will show a message saying DNS Lookup Failed, and an icon will pop up in the right corner of my screen with a yellow (!) triangle. If I hover over it, it will say no internet access.I've followed the few steps they had on there, but none of them worked. I've never had a problem like this before, and haven't made any modifications to anything on my computer lately, so I am pretty confused as to why this is happening. I know it is something on my end, because my roommate's internet is just fine, and even used my ethernet cord on her computer, and no problems at all.

Cisco :: 5508 Web-Auth Cert Crashing When Loaded

Sep 24, 2012

I have a cisco 5508 WLC that I have setup WebAuth on and trying to install the certificate on.  I have generated the csr and gotten my cert from Verisign (X.509, server platform=apache).  I have followed the instruction via the cisco documentation url...I found an error in uploading and find out how to encrypt mykey: url...

I am also having exactly the same issue with a certificate from Thawte.  I followed the unchained guide and have tried both with and without a password in the initial step key generation step, requesting a new cert each time. As with Jeensernchew's issue there are no errors in OpenSSL but when uploading the cert to the WLC get the following error. [code] The WLC is running version  I am using OpenSSL 1.0.0 29 Mar 2010.
When I requested the cert from Thawte I was asked to specify the device type, I chose Cisco, but as all the work and conversion is being done by OpenSSL, should I have chosen differently? When I do this I can load the cert in the 5508, but the controller fails and doesn't allow that VLAN or config access to the wireless network.  I am at a loss of why I can load and it not work.  I have verified my hostname and password and those are good.

Synology DS1511 NAS / ISCSI Initiator Crashing Server 2008?

Aug 16, 2011

I have a Server 2008 server and a Synology DS1511+ Nas.The goal is to make an iSCSI connection from the Synology to the Server 2008 server. However, I am having an issue. I set this all up two weeks ago. For two weeks it was all running fine. Now, my iSCSI drive is dropping daily. And everytime I go into the iSCSI initiator and click anything, the server still allows me to do some things, but it basically locks up. I can't restart, services stop responding, etc... The only was I can break it out of that is a hard reset. Why iSCSI initiator keeps taking down my entire server to the point of hard restart? Once this is solved, I bet the iSCSI dropping daily will be solved as well. I have already talked with Synology, the log is producing nothing and they are suspicious that it has been running fine the past two weeks. Windows update is off (I manually do it during scheduled maintenance), and there is no av or firewall running, so rule those out.

D-Link DIR-655 :: How To Set Up Wireless Network Security

Jan 5, 2011

I read the manual and went on the different options on [url],,,.1 and as far as I understood to set up a wireless password you need first to select WEP or WPAx. I did not see page 63 from the manual Section 4 Security "Enter a password between 2-20 characters. The router will generate a passphrase or key based on your password."

D-Link DIR-655 :: Wireless Network Disappear?

Feb 14, 2012

My internet speed was very slow so I re-set up my wireless network again. After re-setting up, my wireless network always disappears when all my wireless computer/phone get off the network for several seconds. When I try to get my wireless connection again, none of my devices can detect it. In addition, the light of the wireless sign on my router is constantly on (blue), but no device can detect the it. I always have to go to my wireless set up and save my setting again (no change to the current setting). What can I do to fix my wireless network, so it will be detectable at all times?

D-Link DIR-615 :: Spying On Own Wireless Network

Dec 14, 2010

My Main Hardware:
D-Link DIR-615 Wireless Router (WPA2 encryption)
TalkTalk Broadband Modem (wireless turned off)
Windows 7 Desktop PC downstairs

Additional Wireless Devices:
Windows XP Net book
Nokia n900 Smartphone
Samsung Genio Slide phone

The net book and phones connect to the router wireless to receive an Internet connection. As a learning experience and a bit of fun, I wish to use my Windows 7 PC to spy on the activities of these wireless devices. E.g. I use the n900 to log in to a website and I want the PC downstairs to capture my log in details. Can this be done with WPA2 encryption? If not, if I drop the encryption down to WEP, how can I then achieve this? Since I am using my own network, on my own devices, this shouldn't be classed as illegal right?

D-Link DIR-625 Wireless Network To World But Not Office

Jan 19, 2011

I have a wireless router (D-Link DIR-625) connected to the modem for our high speed DSL. I have two Brother MFC printers, one is a laser (MFC-9420CN) connected w/ a Cat-5 directly to the router, the other is an ink-jet MFC-6490CN and I would like to use it wireless....but I could connect it to the router if I need to.I have wireless connection to the internet, from my HP 32-bit PC (running Vista-Ultimate), but can not see either of the printers on the network, and cannot print to either. I manually configured both to have an IP within the range of my network, but they still do not work.The problem (I think) could be with the IPCONFIG. (I had no problem last year, but we recently had a few power outages, and now the PC doesn't seem to 'see' any of the printers.) I checked the IPCONFIG. it states 'media disconnected', but I can ping the one wireless printer??? I can not ping the laptop on the network or the laser printer (I confirmed it's ipconfig before pinging).

I know the network card can't be bad, or I couldn't get to the router to access the internet. I also went into the cmd prompt as the administrator and did the /release/renew/all but that didn't work either.

D-Link DIR-615 - Cannot Connect To Wireless Network With Laptop

Jan 8, 2012

I have recently moved and I brought my wireless router with me from my last home. The wireless router is a D-Link DIR-615 Wireless N Router. I reconfigured the router with a new connection name, password and security key. Upon trying to connect to the wireless network once it was fully reconfigured (no problems reconfiguring whatsoever), I was getting the "Windows was unable to connect" message. Since then, I have been able to connect successfully to the network with an iPod Touch, Xbox 360, Playstation 3 and my roommate's laptop. I have tried resetting the router and modem with no success. I can see the wireless network in the available connections list and other networks in my area. I can also connect to the internet through this router manually using an ethernet cable (which I am doing now, to post this message). I submitted my computer's specs using the SysInfo app given at registration.

I will also include an IPCONFIG /ALL as I have seen this requested in other threads like this one. These are the results of that: (note: this was run while connected through the wireless router using an ethernet cable)

D-Link DIR-615 - Can't Connect To Wireless Network On Vista

Jun 30, 2011

I recently bought a windows laptop running vista to do windows testing on for web development (I use macs normally).I was shocked to find that I can't simply push connect, enter a key and then be connected to our home wireless network... no of course not because it's windows and nothing is easy or practical.Anyhow, before I go on an anti windows rant, I actually need this working.So at home we have a wireless network secured by a 32bit WEP key.On our macs I simply push connect, enter this key and we're away.With my new vista machine I go to Network & Sharing Center -> Connect to a network and click our network.I'm then immediately met with a screen that says "Press the configuration button on your access point". I have no idea what this means.Down the bottom of the screen there is an option that says "I can't find the configuration button... I want to enter the network key or passphrase instead" Which I click.The next screen I click "Enter/Select additional log on information" but this brings up a user name/ password/ login domain screen... I just want to enter my 32 bit key and be connected. I'm using a D-Link DIR-615 wireless router.Also, when I run "ipconfig" in the command prompt I get."Media State....: Media disconnected"
