Has IP - Cannot Ping / Connect To Sites

Feb 17, 2013

I have a laptop that works perfectly fine when plugged into a network cable, but the wifi refuses to work. It pulls an ip, and everything looks good when I run ipconfig/all, but it can't even ping the router. All other computers on the network are working fine. I've flushed dns, set static IP and DNS, uninstalled/reinstall device, updated drivers, bios, and firmware, and even created a backup image of the computer and reloaded the os using the recovery partition. The event log doesn't tell me anything, and there are no flags in the device manager. I'm at a complete and total loss. I cannot figure this one out.The laptop is a Compaq Presario CQ50-142US. Vista 32bit OS. Everything was working perfectly fine before it got a virus. I ran through the standard procedures of AVG, Malwarebytes, TDSSKiller, and even resorted to Combofix, but somewhere along the line the wifi dropped off and will not come back.I even double checked the HOSTS file and IE proxy settings to ensure I wasn't crazy; although I know those should've affected the wired connect too.My last step is to either replace the wifi chip (which I don't think is the problem), or wipe it and load the os from scratch, but I don't have an oem disc since it has the recovery partition.

IE / Firefox Not Connecting But Can Ping Sites

Jul 14, 2011

I have a Windows7 laptop that was working fine til yesterday.I switched it on at home last night and it picked up my wireless connection but when I opened IE or Firefox it would not access any webpage (blank screen, no address that its resolving on status bar at the bottom and just a progress bar (IE) or a 'searching' icon (firefox)The network connection page in control panel says that it is connected and I can ping sites from the command prompt and some other software such as skype seems to be connecting.I have disable both bullguard firewall and made sure the windows firewall is off.I have come into work this morning and am getting the same problems, even when connected by ethernet cable, I can also see other computers on the network.I was occasionally getting a dial up connection pop up box appearing from an old dial-up connection I had set up, but have now deleted this connection.

Cisco WAN :: T1 1700 Cannot Ping From Sites

Dec 19, 2010

I have two sites with a dedicated, point to point, LAN, site 1 has a Cisco 1700, LAN IP: 192.168.0.101; Site 2 has a Cisco 1800, LAN IP: 192.168.1.101.From site 2 I can ping the router on the other side: 192.168.0.101, but nothing else on that network
 
From Site 1 I can't ping the other network at all,Both sites ping fine to their respective local interfaces. I also noticed, when trying to ping site 2 from 1, the  "WIC ACT/CH" light blinks, otherwise it's off.
 
Site 1 has it's own web connection through COMCAST, site 2 is set to route through site's 1 connection to go out. The only thing the routers are doing are the actual connection between sites, and in the case of site 2, routing web traffic to 192.168.0.100, which is a Sonicwall on Site 1.
 
This was all working just fine, for a long time, up until yesterday, when the problem I described started happening.

10 To 90 Percent Of Internet Connectivity Down - Cannot Ping Sites?

Sep 12, 2011

I have ATT DSL and pretty much every night, I lose a large portion of the Internet. I cannot ping these sites, while the rest of the net works fine. The other night, I could not ping major domains like ATT, CNN, MSNBC, BBC (a chronic missing domain). On the other hand, I could get Yahoo fine and go to a streaming audio site and run music perfectly...but about 90% of the Internet was unreachable. Could not load their sites nor ping them in command line. The other 10% worked flawlessly.

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?

Can't Connect To Certain Sites Programs?

May 20, 2011

Can't connect to sites such as this GamersFirst Forums -> International APB Reloaded Forums, unless I use a proxy site.Nor does connecting to the game works, either. But it works for my friends, apparently.I checked the router settings, no go. Turn the firewall and Norton on and off, and still the same. I even tried accessing on my sister's computer which is also connected to the same router, and it connects. Only my computer doesn't connect to some certain sites.

Can Connect To Some Sites Only Via Proxy

Jul 20, 2012

I can't access some sites, loading times are endless and they look totally strange when I can access them (No images and so on). Sites are completely random, some examples are GamersLegacy.it - Starcraft 2, Diablo 3, Dota2, World of Warcraft, League of Legends, Inferno eSports - Homepage (videogames forum)FINECO: Conto, Investimenti, Trading, Prestiti e Mutui - Banca diretta, online o con promotore (bank) Sigma Draconis

1) Cleaned laptop with Ad-aware and Malwarebytes, found 2 issues but didn't fix the problem.

2) Closed firewall, nothing either.

3) Canghed/flushed DNS, tried both openDNS and GoogleDNS, nothing.

4) She CAN access those sites, she has same connection to the router (via wireless) and she has same OS (Windows Seven). I think that means it's my problem, not a router one.

5) Tried to lower MTU settings in my wireless connection as I read that could be the problem, nothing new here.

6) Here comes the tricky part. I tried to access those sites via proxy (Ninja Cloak | Fast, free, anonymous web browsing with NinjaCloak.com) and they actually work!

D-Link DIR-655 :: Can't Connect To Certain Sites

Dec 3, 2012

I have dir655 Hardware Ver B1 Firmware Version: 2.10NA.Comcast Motorola cable modem surfboard SB5101. The problem started happening a couple of days ago. When my computer is hooked up to the cable model directly, i am able to connect to outlook.com just fine but when i go through my router, it can't connect to the site. I played with MTU (lower it by 10) all the way to 1300 but it didn't work.The problem started happening all the sudden without any changes in the cable modem, router or my computer.

I also tried cloning MAC address from my pc but didn't work.I also tried turn off both modem and router, wait 2 minutes, start modem, wait for all lights to come up and start the router.Sites i can't connect are: outlook.com, starcraft2, Comcast, eBay, Facebook.One thing that i noticed weird is that i am able to connect to cnn.com using IE9 just fine but ping shows: [code]

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.)

Cannot Connect To Specific Sites At Home

Sep 26, 2012

I'm trying to solve up a really nasty problem I have at home and I've come here hoping to find some answers. Since last Saturday, I am unable to access certain internet sites when at home. Strangely enough everything was fine before that. Went to bed around midnight local time and when I went to check those sites after work at around 3:30 pm local time I could not get on those sites. For some reason the pages just keep on endlessly loading, giving me only a blank page. What is also strange is that no computer in my house can access those sites. So it's not limited to one computer.

Sbs2008 - Best Way To Connect Remote Sites

Nov 15, 2012

I have inherited a sbs 2008 network where they have a SBS2008 server and Server2008 running as a terminal sever at the main office and they have 2 satellite offices. These offices all connect through router to router vpn tunnels. The main site is on 10.0.0 and dhcp is done by the sbs. Satellite site a is on 10.0.10 and dhcp is done by the vpn router and Satellite site b is on 10.0.5 and dhcp is also done by the vpn router. All client computers can run rdp to access shares / programs etc on the two servers but when trying to push out group policy, antivirus updates or even using remote control through the SBS2008 server it is hit or miss. DHCP records on the SBS server do not seem to update correctly, manually changing the ip address in DNS records results in warnings that the PTR record cannot be created.

So I am wondering if the configuration they currently have setup is correct. What might be stopping some but not all computers from updating, why I can connect to some but not all computers at site "a" but I am not able to remotely connect to any computers at site "b".Why I can do remote installs of Eset Endpoint Security on roughly 10% of the clients but the other 90% fail.

Can't Connect To Certain Sites Via Wireless Hotspot

Dec 9, 2012

My only options for internet have been 56k or wireless USB modems. That is, until recently. We switched from the wireless USB modems to a wireless hotspot from US Cellular (Samsung SCH-LC11). However, ever since making the switch I've had problems accessing certain websites both on our PC and on my Macbook Pro. I can't connect to Invision Free (or any of its user-created forums) or [URL]. It happens with other, random sites as well. I tried manually changing DNS settings to Google's and another one (don't recall which) and it did allow me to access the site. However, once there, every other site started moving slowly and eventually the ones in question timed out as well.

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:

[URL]

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

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.

Linksys Wireless Router :: WRT54G Cannot Connect To FTP Sites?

Feb 1, 2009

I could not log into any of the 4 FTP sites that I normally update without immediately getting disconnected. The message I am getting from the servers is "Port command failed, error loading directory - disconnected". To save some time and posts, here are the facts....1.) It is definately not my DSL modem. When I connect directly with the modem, without a router, I can connect to FTP fine2.) I have already done a /flushdns in IPconfig.3.) I have already done the typical power off/power on/reboot procedure numerous times.4.) I have already tried PASV mode, and tried turning PASV mode off as well.5.) My login information is correct, and I have problems on multiple sites.6.) This problem has been reported before by other users of WRT54G, but the other forums I see have no solution to the problem.7.) I have already tried using other PC's and different FTP clients on my home network. No matter which PC or laptop I use behind the router firewall, I can't maintain FTP connection. 8.) I have never had to open ports to be able to connect to FTP, since I am the one doing the request. I did also try opening ports 20 and 21. 9.) XP firewall is disabled. 10.) I have tried both ethernet ports on my PC. But then again, that is irrelevant because none of my other PC's which connect wirelessly, can connect either.

Cisco Firewall :: 5505 / Can't Connect To All Sites Outside From Inside

IPconfig shows wireless adapter at 192.168.1.3. When router is attached it's ip is 192.168.1.1. Disabled the wireless in the settings but no dice.

Can't Connect To DNS Or Ping But Get IP From DHCP

Aug 28, 2012

My parents Windows 7 PC has suddenly stopped being able to connect to the Internet. Using the "Diagnose problem" feature in the Manage Network Interfaces panel results in a message claiming that it cannot reach the DNS server and that the connection needs to be reset. Doing so has no effect. It is connected to a DSL router via an ethernet cable.The NIC is set to dynamically receive its IP and DNS settings via DHCP which it obtains from the DSL router. Executing ipconfig from a DOS prompt shows that this is occurring as expected, with an assigned IP of 192.168.2.10. The gateway and dns are set to the IP address of the router, which is 192.168.2.1. Note that I can't even ping the router at 192.168.2.1.I also tried static settings in the available range and tried using open DNS IP addresses.

They also have a laptop which connects to the same router wirelessly using DHCP and it is working fine. Using this laptop, I can log into the router and see both it and the problem PC in the list of connected devices, each with the dynamically assigned IP addresses as seen using ipconfig on each. Unplugging the ethernet cable shows the connection status changing in the list of connected devices in the router. From the laptop, I can ping the router and running ipconfig shows that it obtains the same gateway and dns as the PC and the next available IP - 1292.168.2.11.So this leads me to believe the following:

1- The router, NIC and cat 5 ethernet cable are working fine at the hardware level.

2- The DNS settings in the router are fine, as the laptop works

Perhaps coincidentally, the same day it stopped working they received one of those bogus "This is Microsoft calling" calls claiming their PC was infected, but they had heard of the scam and hung up. Naturally, I started suspecting a virus, but a full system scan using McAffee produced nothing. If it was a DNS changing virus, would I not still be able to ping the router using the IP address?
