DNS Server Can't Be Resolved - Unable To Visit Many Sites

May 9, 2011

Lately I have been experiencing an annoying issue with my connection. My signal strength is excellent, but every 5-10 minutes I have the problem that the DNS server can't be resolved, so I can't visit any websites. All I can do is wait, the problem disappears after a few minutes. I tried ipconfig /flushdns but that didn't work.

Unable To Connect To Certain Sites On The Internet?

Mar 14, 2013

I'm having problems connecting to certain sites on the internet through one computer. I can connect ok on other computers going through the same home network. On the one computer that is having problems I can connect to the site but then when I click on a link I get unable to connect then I can reload the page and some times it connects to the page. So as I am browsing through the site almost every time I click on a link I get unable to connect and have to keep reloading the page.

Unable To Connect To Certain Sites With Linksys

May 1, 2012

We can't find the Linksys router's manual and have no clue what is causing our WiFi not to let us access certain websites. For example, we are unable to access the Microsoft, Target, our local Library, YouTube and some other ones that we find out about once it doesn't let us get on them. We thought it was an issue with Microsoft Security Essentials because we hadn't updated it correctly, but that was not it. The reason we know it is OUR WiFi because we can access the sites I mentioned above whenever we use our apt complex WiFi, so it is not our laptop. We have the same problem with this when using our wifi on our iTouch. I hope that all made sense (had to access this site with my phone.)

Unable To Connect To Random Sites?

May 7, 2012

I built a computer down at school in Utah, semester's over so I went back to Idaho for the summer. When I got here I seemed to stop being able to connect and load content from random sites. It gets a ping time out every time on the same random websites.

Some of the sites:


I can access these sites in Utah, so I called my ISP (frontier communications, previously verizon.) They flushed the DNS and checked that the modem wasn't to blame. I checked my host files and they're unaltered. After two hours on the phone they were stumped and hung up. [URL] loads fine, but it won't load the pictures which is odd.I'm not sure if it matters but I do have a 6 year old modem (westell 327w) that I think uses LAN g whereas my mobo (asrock extreme3 gen3) uses Realtek 8111E if i'm looking at the correct specs.one last thing to add would be that I am not able to access [URL], but I am able to access [URL]. Is there something all these websites have in common that cause them not to load?

Unable To Connect To Unsecured Wireless Sites Using USB Realtec

Dec 6, 2012

Unable to connect to unsecured wireless sites using a USB Realtec high gain antenna on a Toshiba laptop running Win7 Pro, 64 bit. Network troubleshooter resets adapter but states it cannot correct the problem. Wireless adapter settings set to High Performance. Latest Realtec drivers have been downloaded and installed. Light on front of the laptop shows that the wireless function is running. Turned the function off, rebooted and then turned it back on. Same result when Toshiba is operating off 110v so power shouldn't be the problem.

Can't Access Google Sites - Server Not Found

Jun 10, 2011

Everytime i try to go to a site that uses a google server, i get the message "The server at www.google.com can't be found, because the DNS lookup failed. DNS is the web service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network."

Cisco Wireless :: 3602 AP Unable To Ping Anything At Branch And Central Sites

Mar 7, 2012

We are in the process of evaluating Cisco wireless controllers and AP. We have 3602 APs and 2504 controllers right now. We have multiple branch offices connected to the main office through layer 3 and they all have different vtp domains and vlans. I am trying to deploy APs at the branch offices and connect them back to the controller and the central site. I created a sub interface and ssid with one of the vlans at the branch office on the controller and was able to get the AP to join the controller through DNS. However, a client at the branch office connected to the AP was unable to ping anything at the branch and central sites. Any documentations on how to deploy such a setup where the controller is at the central site and AP at the branch office going through multiple routers in between?

Cisco WAN :: 881 Unable To NAT To Web Server

Jun 20, 2011

Apparently the problem seems simple enough however I couldn't get it working. My router is being configured to access a web server in the network which is on port 80. However, port 80 is being used by my router's setup page. Therefore whenever I key in my public IP address, it will just immediately direct me to the router's page.I have also tried opening up other ports like 5050 and set my web server to port 5050. Internally within the LAN itself everyone can access the web server with port 5050. However, going from public IP address with port 5050 doesn't work.

Unable To Contact To DHCP Server?

Nov 2, 2011

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues. For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

Unable To Set Up The Server And Open Up The Port?

Dec 18, 2012

I've been trying to open ports to start a server on some games that I play.I used a guide that shows you how to set up the server and open up the port, but I can't get it to work.I've tried making an exception in my firewall,but that didn't work, so I tried completely disabling my firewalls. Nothing. I've gone into my router settings and opening a port this way: But it still doesn't open it up. This is what I'm using to check it.In fact, NONE of the ports are open it seems? No matter what port I try to type in on the port checker, it always gives me that same error.

Unable To Resolve Server's DNS Error

Apr 23, 2012

My laptop is connected to a router via wifi but it keeps getting a DNS fault. I have another PC linked to the same router via WiFi and that works perfectly all the time. I have the same problem on both google chrome and IE browsers where I just get the message telling me that the DNS look up failed. My internet is still connected as I can dial into my remote CCTV cameras and I can ping website ip addresses. Most times I can just turn off my wireless adapter and turn it back on and it works for another hour or so. But sometimes it wont work all day, unless I start my laptop in safe mode, when it works everytime! I have flushed the DNS cache several times but to no avail.

Unable To Send Files To FTP Server

Aug 14, 2012

I have a server with two adapters: and, connects to a cisco router (which I have no access to). This connects via WAN to another network to transfer files to another company. is connected to our local LAN. I have a service that uses FTP to get and send files to a server through I recently had to switch our IP scheme from 10.99 to 192.168 and since then haven't been able to send files to the ftp server. My question is, would a router solve my problem? If so, would I; remove the 10.99 adapter, connect 192.168 to the router, connect the router to the switch, connect the 10.99 gateway to the new router (and update any appropriate routing tables on the server)? The service appears to have issues with using a dual homed server and updating it isn't going to happen anytime soon.
