Windows 7 Incorrectly Reports No Internet Access
Oct 25, 2011
I'm connected to my router via an Ethernet cable, and on the connection icon I have the yellow triangle and a message indicating I have no internet access...but I do. My internet is fully connected and I have no problems remote connecting to my computer from work, downloading and seeding torrents or browsing websites. Problems is, it seems that Windows THINKING it's not connected is affecting other programs which need to connect to the internet.

we have a 4510r-e running 12.2(50)SG1 w/ various rj45 line cards and a 24 port glc card.at any given time, i see 10's of ports in 10/full.i go to the station, and find the station in 100/full or 1000/full.
i go to the switch w/ my fluke, connect it directly to the switch w/o any intermediate infrastructure except a 50cm cat6 patch cable.the fluke reports 1000/full, but THE SWITCH PORT REPORTS STILL 10/FULL.all ports are config'd 'speed auto' and 'duplex auto'.
the switch seems to be erroneously reporting 10/full.there are no errors logged on any of the ports and there is successful communications even when the station and switch port report different speeds.even though there are no errors logged nor reported by 'show int [port]' nor 'sho int count error' certain killer applications crash on some stations. (the applications are GHOST (which dumps disk images from a server to multiple stations) and NETOP (which i sused in a classroom to transmit an instructors screen to a room full of stations) both of which broadcast and/or multicast.all nodes involved in the above 2 applics are on the same vlan and same phyiscal subnet.
the ports which report 10/full vary and occur even when the above applics are not in use.the only way i found to clear this 10/full report is by either a hardware reset of the entire module or by unplugging the cable, the execute on the port shutdown, speed auto, no shutdown, reconnect cable.then it's just a matter of time until it pops back to 10/full in a few minutes,hours or days.
how to address the killer applic problems besides restructuring the whole net by defining separate vlan for each lab of 20 or so stations?

I have an issue that started showing up since I bought a new computer. The old computer ran XP, the new one runs Windows 7. Almost every time I start the computer I get an error message telling me Windows has detected an IP conflict. Sometimes when I click okay I get the message a second timeAbout half the time, I have no internet connection when I start up and have to restart my router, which fixes the problem (after restarting the modem, I do not need to do anything like renew with ipconfig; it just starts working). I do this so often I attached it to a power switch to make it easier than unplugging.My setup is this. My PC is connected to a router connected to my cable modem. The router is also connected to a wireless hub. This hub is used by only one device, my Wii U. I can get the error message even if my Wii U is turned off.

We have a Cisco ACS 5.2 deployment (appliance). It has an existing integration with Active Directory. We utilize this with RADIUS to authenticate our wireless users and TACACS for managing our network equipment.The RADIUS reports are useful for other teams (outside my own) to be able to troubleshoot password and account lockouts (everyone forgets to change the password on their phone).I would like to allow this team and other access to view the RADIUS authentications report.

Im now in charge of a medium/big size network (around 1200 machines).I found some connection pattern that im not shoure if it is correct.I migth be wrong, but i think this kind of connection would cause a continue RSTP change of topology (confusing about the 'direction' of the route to take), so having some latency period (this pattern of connection can be repeated several times in the whole network).BTW, there is no special configuration in switch A for saiyng that port 50 is not being used as a uplink port.

Dell Support Center (Inspiron 6000, XP SP3 Home) insists that there is no internet connection. In fact I have a perfectly good wifi service both to the local network and the internet. I have seen lots of other reports of the same problem on the web but can't find anything in the forums. I have given access to DSC in Windows Firewall

What is the impact of incorrectly setting the antenna gain on a the b/g radio of an AP would have on a WLAN?
I've come across a site where around a 3rd of the AP's had their antenna gain set to 0. I can only assume that something missed setting this during setup. The site uses 1242ABG AP's and each has 2 4941 antennas and i believe the gain should be set to 4 x 0.5dBi

I ran into this recently with a client of mine. When uploading files (either via FTP or through a shared drive in terminal services) from the site any files larger than 200MB or so would hang in the middle of the upload as the TCP session timed out because the traffic was cut off. I started pulling apart the config on the 2911 edge router to determine what the issue was.
I trace the issue down to this particular policy which was created by CCP: sdmappfwp2p_CCP_LOW (When this policy was removed from the wan interface the issue vanished). The default config of this policy was as follows:
policy-map sdmappfwp2p_CCP_LOW
class sdm_p2p_edonkey
drop
class sdm_p2p_gnutella
drop
class sdm_p2p_kazaa
drop
class sdm_p2p_bittorrent
drop
I first removed the highlighted drop command from the edonkey class and reapplied the inspection policy to the WAN port and the issue remained resolved!
While this fixed the issue and I was able to block eDonkey traffic with just a simple outgoing ACL to block tcp port 4662 I find it very strange that a eDonkey inspection policy would cause such problems for eDonkey traffic. I know for sure this is the only change made on the router and I'm just scratching my head at what I've found. Is it a bug with NBAR? Mostly I'm just curious as the issue is already resolved.

Using Outlook to send & recieve mails from a webmail hoster, I regularly get booted off the internet and am left with the Limited Access message. Usually unplugging the router clears it but it is a nuisance to say the least.I have even tried reverting to a cable but the problem continues.The problem even happens to my wife's Samsung laptop, although the info below is from mine.

I own a desktop hp pavilion windows xp that i recently reset to factory settings and now I'm having trouble getting wifi. The other computers in my house work fine with the router, and my computer gets internet through an ethernet cable, so I know it isn't the router. I used to use a d-link G rangebooster desktop adapter to get wifi, and I have tried downloading a driver for it but still no luck. Some of the things I have tried are as follows:
-Renewing IP address
-going through new wireless network wizard
-unchecking the "IEEE 802.1x authentication"
-creating a new network for the "preferred network list"
-other random edits that have not worked!
The wireless network connection says signal strength is excellent but status is limited or no connectivity.

my primary source of internet at my house for the passed year is an at&t 3g usb modem (sierra wireless lightning), becuase i live in the middle of nowhere (only other option is satellite). Up until now i've been using a wireless ad hoc network to share the connection with multiple computers. I just purchased a cradlepoint router that is compatible with my usb modem so I can have a "real" wireless network in my house. I set it up yesterday and so far its working great, I have a wii streaming netflix, an android tablet, an iphone and two laptops (running vista, and win7 respectively) currently connected. The problem is my 3rd laptop, also win7. It is my primary computer that I use for business and absolutely essential that its connected to the internet. It (seems) to connect to the wireless network just fine, but gives me a "no internet access" error.
This laptop will connect to other wireless networks: it always connected to the ad-hoc, it will connect to my wifi at work and the network at my boyfriends house, also i just tried it with the verizon 3g mobile hotspot app on my droid and it connected right away. It also works just fine with a wired connection to this router (ethernet). I'm not sure where to start since every other device in my house is working with this network and this laptop will connect to other wireless networks.
ps/ Going through the windows onscreen troubleshooter it will either tell me "there is a problem with your broadband modem" or "There is a problem communicating with DNS server" (but it wont fix it)... and after going through endless google searches, i've done everything thats been suggested so far (making sure dhcp is enabled, powercycling the router/modem, updating drivers, ipconfig release/renew, disabling the firewall).

I had an issue with my Win 7 networking on LAN but no problem on wifi. When I plug in the network cable, it takes very long time to detect, and when it does, it shows Unidentified Network - No Internet Access and stays as public network. I do not have the normal options to choose Home, Work or Public Network. This happen at my work place. But my colleagues which on Win 7 have no issue. I tried to uninstall the anti-virus, disable the window firewall, but still fails to detect. There are few LAN port at my work place but it produce the same issue, very, very slow to detect.

I have a sony vaio VGN-NW20EF running windows 7, It use to work fine but now I can't access the internet wirelessly. It detects and connects to networks wirelessly and it even says I have internet access but the msg cannot display the webpage keeps coming.
It works fine with the ethernet cable. It works fine wirelessly if I use my mobile phone as a hotspot as it's a HTC HD 2 and works as a router on the go, through the phone's internet. I've restored the computer to the earliest date available and no luck.

I have 2 desktops and a laptop accessing a wireless Motorola modem using roadrunner broadband. My desktop/Vista and laptop/Windows 7 are working fine. My older desktop with XP has a wireless card and shows that the wireless is connected with great signal strength but won't access Internet Explorer. I keep getting an error message. I have tried re-setting up the wireless and shutting down the machine ,etc. I have seen a few older posts that suggest downloading some software, etc

I have a new Windows 7 laptop that is replacing an older XP machine that has successfully operated for a number of years with internet connection sharing from an XP desktop host computer. I am unable to set up the new machine to access the internet. The SysInfo data for the new computer is:
Tech Support Guy System Info Utility version 1.0.0.2
OS Version: Microsoft Windows 7 Professional, Service Pack 1, 32 bit
Processor: Intel(R) Core(TM) i3-2328M CPU @ 2.20GHz, x64 Family 6 Model 42
[Code].....
The client has its IP address set automatically by the HOMENET wireless router, along with a manually set gateway address to route internet signals through the host computer rather through the router. I am new to Windows 7 and have not been able to set up the client to see or share files between the host and client when connected by wireless. When connected by a LAN connection to the router, I can see both computers and share files between them, but have not been able to connect to the internet. The Win 7 machine can connect directly to RESNET and access the internet that way but the incoming signal averages about 45% which is far below the level needed for acceptable use.

I unplugged the power to my HP Win7 pc, but left the phone line hooked up to the DSL modem which was connected to the pc. Apparently, we sustained a lightning hit while we were gone. After powering up the pc, I found I had no internet access. Found the modem was bad as well as the monitor. Replaced the modem and monitor, but still no internet. Using an old pc, I have internet access. I'm guessing the motherboard also controls internet access.

I have a couple of computers in my house that work fine with my wireless router, but all of a sudden, my roommate's computer, a Dell Inspiron with Windows 7, is connection to the wireless network but has "no internet access." I've rebooted th.e modem and router, to no avail. I've also tried a number of suggestions online, but without success. My friend's computer has McAfee, with which I'm unfamiliar. The only real difference I cn see between our computers is that she has a different wireless card.

I am running a VPN server on my desktop at home, with all the default settings, and i checked the box that allows clients to connect over the internet. this is win7 x64 computer. I opened up port 1723 with PPTP protocol on my E4200 router.On the client i am running win7 x64 as well. I am able to connect to the vpn, from another internet connection, but there is no local network acess. It says the status is No Internet Access. and the IP that is assigned is the 169.x.x.x one that windows defaults when it doesnt find a dhcp server.How can i get the client to connect with full local network access. Right now being connected to the vpn, it means nothing, i have no access other than being "connected".

I recently had my Internet disconnected, and decided to share my iPhone's Internet connection (tether) with my PC. Now, the iPhone connection works, but for some reason my PC prefers to use my original Internet connection thus no connection. The only way I can access the Internet is by going into adapter settings and disabling my router, but I do not want to do this as I have other computers on the network and I often share files.

I am now unable to access the internet with my Dell 560 running windows7. I have Verizon Fios for internet access. Windows network diagnostics reports that the connection between my access point,router or cable modem and the internet is broken and the network gateway is accessible but windows could not receive network traffic from the internet. Verizon's in-house -agent reports that there seems a connection problem between my router and the wall jack. I am able to access the internet with another computer and the the same router. I also have no problems with my iPad. I have interchanged cables and ports on the router.
