I'm running Win7RC1. I've got it on 3 computers now. Two of the computers are Dell laptops. Both, after RC1 install, exhibit the same symptom: I have a yellow warning / exclamation point (black on yellow) overlay on my wireless icon in my systray. When I rollover it says "no internet access". If I open Network & Sharing Center I can see a red "X" over the connection between my home network icon (little house with a nice red roof) and the internet globe. Access type reports "No Internet access". All that would suggest I can't surf, yet here I am, filling out this form on the very same computer. I was living with it for a bit and didn't concern myself much with it but last night I upgraded my wife's laptop and she's having the same symptoms. Both computers were running Windows 7 beta before and they did not have these symptoms or issues. This is new since the public beta. Neither computer has a wired connection to the network. There are no special characters in my SSID which is like AB123 (SSID changed to protect the innocent). When the problem first appeared on my first laptop, I reinstalled the network drivers from the Dell website (Vista 64-bit). This corrected the problem for the rest of the evening, but I noticed it was back the next day. This laptop isa Dell Latitude E5500.

Mostly identical situation except for hardware/VM. Previously ran the beta too. Running RC under virtualbox in Ubuntu 8.04. All works fine except that yellow triangle is annoying. Dell Inspiron 530.

Hello,Thank you for running Windows 7 and helping us create a better experience. Can you explain your network setup? Are you connecting to the internet through a proxy? Who is your ISP? Does it report "Internet access" for a while and then transition to "No Internet access"?Would you be willing to gather tracing? To do so, please take the following steps:1) "netsh trace start nid_wpp,InternetClient capture=yes"(from an administrative prompt)2) disconnect and reconnect to your network3) wait for 1 minute4) make sure the tray icon is still reporting no internet access5) "netsh trace stop"(from an administrative prompt)The last command (from #5) will print out the location of an *.etl or *.cab file. Please attach that file to an e-mail and send to ahardin@microsoft.com.Thanks,Andrew HardingMicrosoftedit: I've added an amendment to #1 above

Verizon FIOS with Verizon's M1424WR Actiontec router/WAP No proxy It never displays "internet access". Check your inbox for email Michael Green

i am similar situation, though internet works fine for a random amount of time but usually fails after 50 minutes to and hour. everything works fine then the yellow exclamation comes and i lose all connectivity i either have to wait 2 minutes for it to right itself or manually disconnect from SSID and reconnect. i am going ot try time a trace to coincide with one of these disconnects and email it later edit: ok i managed to start a trace and 15 minutes later i got the yellow exclamation mark 'limited access' i will email u the results

Please use the amended instructions above to gather tracing.Thanks you!Andrew

ok thanks i just had my 'limited access' about an hour after my previous one and missed the post , so ill run it again in 50 minutes and hope it happens again.tylike clockwork it happen 1 hour after previous 'limited access' the capture file is 25mbi will try send it now :)if its too big i know now it happens exactly an hour after previous timeso i can properly time my trace to be a lot shorter.

a temporary solution for meto the yellow exclamation mark is to disable the windows firewall, wether its the cause or part of the problem i don't know but looking through firewall log in event viewer i see the connection swap from private to public whenever i got limited access and yellow exclamation mark. Either way disabling the firewall has left me with a steady 3 hour connection so far whereas before it would only last 50 minutes to an hourjust as i post this i get yellow exclamation mark......

ok this is a long shot and seems very very odd, but ive managed to duplicate it twice so here goes:start pc as normal let wireless connect etc.. 1 hour later i get yellow exclamation as normal and dc.. to stop this from happening all i did was open the network and sharing center and left it open, i had a connection for 8 hours to make sure it worked then i closed the network and sharing center. exactly 1 hour later the yellow exclamation mark appeared, instead of disconnecting/reconnecting from wirless network all i did was open the netowrk and sharing centre, within seconds it reconnected itself.i realised what it was as ealier i had the netowrk and sharing panel open and had closed it about an hour before i lost connection at 3 hours.to confirm my findings i will leave the network and sharing panel open for another few hours then close it and see if i get the yellow exclamation an hour later.i have absolutely no idea why this stops it from happening and what the network & sharing center is doing in the background while it is open.

I have experianced this with the RC and RTM versions. MY ISSUE: Fresh install of Win 7 x63 or x86, icon shows internet access, windos updates work fine, install office 2007, works fine!Install ANY of these antivirus approved by microsoft (Kaspersky for workstation for Win7, Free AVG, NORTON) all create the "no internet access" warning but internet works fine.UNINSTALL Antivirus software issue goes away!Anyone try to replicate this on their machines to see if my pattern is consistant??

kturley, I was the original poster and my issue is resolved. I disabled AVG then re-enabled it and the problem has not been reproduced since then. The last message(s) I had from Andrew, that was relevant to our topic was: Have you been able to reproduce the original problem? I suspect not. Windows has several mechanisms to determine Internet connectivity. Verizon FIOS networks are setup in such a way that one of the mechanisms is non-functional. In your case, AVG was also blocking the primary detection method, Im assuming through some sort of misconfiguration, and was blocking access to http://www.msftncsi.com from the service responsible for detection. After disabling AVG, the service was able to reach the URL and therefore reported Internet connectivity. After this primary mechanism succeeded, other lesser mechanisms will now be able to report Internet connectivity, even though I suspect AVG is again blocking access to the URL. We have had some other reports of AVG disrupting our Internet detection Do you remember advising AVG to block traffic from Windows Service Host or anything similar? Either way, other Internet detection methods are keeping you at Internet now. We are exploring AVG on our end to see if it is a default setup which causes the problems or if it requires user consent before disrupting things. I answered him saying that I had no memory of telling AVG to block traffic from WSH or anything similar.

I'm having the same problem on all of the Windows 7 Enterprise RTM machines I have setup in our testing lab. The machines have full internet access through a filtering proxy server (Bloxx) which use Active Directory authentication. The "No Internet Access" icon continues to appear despite clearly not being correct as I can browse the net, do windows updates, etc just fine. The machines have McAfee VirusScan Enterprise 8.7i Patch 2 installed which is listed as being fully Windows 7 compatibile by McAfee themselves. I have tried to remove McAfee from the computer's but this has no effect. Could our proxy server be clocking access to the site Windows uses to determine if there is internet connection or not? If so, what URLs do I need to ensure are not blocked? Lastly, will this check obey Internet Explorer proxy settings and use AD credentials of the current logged on user for authentication?

Hello again. It's been a week since the above post. Has anybody come up with a solution to this yet please? I really don't want to be hiding the network icon by policy as we'll need this for wireless network connections, but I don't want it continuing saying there is no internet access when there blatantly is.

This problem reappeared when I reinstalled RC and AVG. Rather than go through all the steps to get cooperation between the two and remove the yellow "X", the problem was resolved by substituting Security Essentials for AVG.Nothing at all similar to your situation but I hope this might help someone out there.

Same issue here.Win7 Enterprise in a domain with Forefront client and ISA firewall client. Internet works fine, network works fine but i see the "no internet access" warning. Updates are being done by WSUS with no problem. Could use some help.

Same problem, However my wired pc drops my internet connection on every reboot and often on resume from sleep. The 2 wireless pc's have no issues? I ran the W7 rc and never had a problem one, i go buy the retail ultimate (same as the RC ultimate?) and began to have these internet issues. i have tried quite a few fixes short of changeing drivers. I hope MS can get us a fix. The W7 forums are full of folks that are haveing this problem!

Getting the same problem will try the AVG fix

Cannot reconnect to the internet when windows 7 resumes from sleep mode.http://support.microsoft.com/kb/937477/en-ushttp://support.microsoft.com/kb/933872For Hibernation issue in windows 7; you can try this.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HidUsbDouble-click FastResumeDisable, type 1, and then click OK.http://support.microsoft.com/kb/975851I'm using windows 7 with Microsoft security essentials, no issues are reported.There were similar issues with vista and the security softwares(zone alarm), which were resolved with the updates.All the Best!

I had networking problems as well. 3 computers running Windows 7. 2 had Adobe CS3 installed which brings with is a piece of software called Bonjour. These two computers had no end of networking problems. 1 was a desktop connected to the router and the other was a laptop connecting via WiFi. Third computer didn't have CS3 and didn't have any trouble at all. In trying to find a solution (nothing seemed to work), I came across the solution shown below in a different thread and thought I would share it. I installed the upgrade for Bonjour (it's listed as Windows Vista 64 software) and all of my network problems cleared up. My thanks to "PDX Prod Mgr". Brilliant! " PDX Prod Mgr I had the same problem when I rebuilt my Windows 7 system. I had CS3 installed on my system, it installs an old version of bonjour. If you inspect your program files\bonjour directory, see if you have an EXE and DLL file dated 2006. Jump over to apple's website and search for windows bonjour. I found the newer download here: http://support.apple.com/downloads/Bonjour_for_Windows Download and install this (you don't have to uninstall the old Bonjour) and reboot. This fixed my install and I no longer have the network error you describe. If you look at that folder now, you will have the newer DLLs (and some other gunk.) "

I have the only Windows 7 PC on a domain of about 100 computers. We use typical settings, no proxy. I do not use bonjour or any Apple products on this PC, except for the quick time plug-in. It is not a major problem, just an annoyance. Most of the time is does not exibit this behavior but once in a while, maybe once or twice a week, the stupid little yellow triangle appears on the tray icon with the ltiile exclamation point. The thing is, my internet access is still working fine, as always. If anyone knows of an easy fix, I'd love to be informed. It's not a big enough problem to be worth going through a lot of troubleshooting, I'm just looking for an easy fix if one exists. Thanks and good luck! Flux
