Cannot Access Internet Despite Apparent Wireless Connection
Nov 14, 2012
I have an Asus Windows 7 laptop with an Atheros AR9285 Wireless Network Adapter. I am trying to access a student communal network (IT support is sadly none-existent) which means I cannot perform tests on the router, but can confirm that my girlfriend can connect with a Macbook in the same room as me, and that other Windows users can too in other areas. I can connect via ethernet into the wall (although not 100% sure this is the exactly the same network) and I can connect to other unrelated wireless networks with no problem. Up until a couple of days ago I was able to connect, but have not done any windows updates that might have changed my settings. When attempting to connect my computer tells me (often, not always) I have "Internet access" under "IPv4 Connectivity", but the browser does nothing (or, sometimes, will struggle and load one webpage, only to fade into uselessness again immediately afterwards - very much a tease of a connection).
1) Disabled various firewalls/antivirus [Microsoft Security Essentials, Windows Firewall, AVG] (perhaps worth saying I have never had Nortons, McAfee or any other anti-virus installed on this laptop)
2) Reset Network Adaptor using Windows Diagnostics Tool.
3) Updated the driver by searching automatically for drivers in Device Manager.
4) Removed and Renewed the Network in "manage wireless network".
5) In Wireless Connection Properties > Internet Protocol Version 4 (TCP/IPv4) made sure both Ip address and DNS address are set to "obtain automatically" [nb: Internet Protocol Version 6 has the same settings)
6) WIthout remotely understanding what I am doing have typed the following into CMD in this order: ipconfig/release,ipconfig/flushdns, ipconfig/renew [for the latter this message is given "An error occurred while renewing interface Wireless Network Connection: unable to contact your DHCP server. Request has timed out."Beyond that, I'm basically out of ideas. Something is clearly not quite right, and yet I can connect wireless to other networks (my mobile phone on 3g emitting a dodgy wireless signal no less).
Here is the ipconfig/all information [being security conscious and ignorant, I have blanked out the ip, and the final bits of the physical address, as well as the connection specific DNS suffix]
If I ping [URL] it either says [currently unable to recreate this] "Unable to reach destination server" for all attempts, or, as currently "ping request could not find host [URL] I notice that it says in Ipconfig/all that DCHP is not enabled. I am sure this was not the case before, when the problem did not exist. When I connect to other wifi networks DCHP is enabled. I have double-checked wireless properties are set to obtain IP address and DNS address automatically. They are at all times (and I have rebooted) - no change to ipconfig/all.
Just installed a DIR-615, not impressed so far I have 3 clients, a Windoze 7 laptop, a Kubuntu workstation (wireless N) and a wireless HP printer. When I enable DHCP reservations and reserve the addresses then save settings the router reboots and when I go back in all info is gone and nothing is reserved. I have been having weird disconnection issues - I lose my internet periodically for no apparent reason so I increased the lease time and am trying to reserve addresses.
I recently swapped a EA4500 for an EA6500 and have been experiencing intermittent Internet connection issues, specifically periodic disconnects (as some other users have reported). The router is connected to a Motorola SB6121 Cable Modem with Comcast as the cable provider. I contacted Comcast and they specify 1500 as the MTU size. With the Router set to Auto, I experience the periodic disconnects. When the MTU is manually set, I still experience the periodic disconnects, and I noticed that a ping test specifying the packet size with the -l switch results in a fragmented packet and is only resolved when the ping packet size is reduced by 28 bytes. Thus, it appears that the MTU specified on the router fragments all packets of that size and up to 27 bytes less than the MTU setting. For example, with the MTU set to 1500, all packets 1473 or larger are fragmented; with the MTU at 1444, all packets 1417 or larger are fragmented. I believe there is a bug in the current firmware, which I have installed on this router as version 1.1.27.141816. Regardless, even with the router set to Auto, the correct packet size is not properly detected and di

I have a wired connection to 12 MBs and is very stable.My problem is that the download speed becomes 12MBs to 2MBs without apparent reason.It is fixes if you restart the router.Here will show you the optimal speed of connection.
I rebooted my modem and now I have not internet access on my wireless connection. The internet works fine on my 3 computers I have connected to cables and my wireless devises have a good wifi signal, but no internet access.
Basically both the wireless connection and LAN connection in my house were working fine until a couple of days ago. I got one of those viruses that redirects all the links that you go on to random websites on the main PC. I ran a full scan with McAfee Antivirus Plus and it came up with nothing. My brother suggested i try downloading malwarebytes on my laptop and installing it on the PC to get rid of it. Malwarebytes picked up the virus and got rid of it. I restarted the computer and when i tried to access the internet on the PC the message on the browser says "Could not connect". My wireless is fine, but the wired connection to the PC is not. When i look at it on the PC it says that it is connected but the browsers show no connection.
I have had my HP laptop for 2.5 years now, originally bought with Vista 64 bit. It now has Windows 7. Up until now, internet access and connectivity have been working fine. But, all of the sudden today, I couldn't get Internet Access despite trying both an ethernet port and a wireless connection (connectivity was working.) I know it's something with the laptop, because my ASUS netbook has no problem accessing the internet. I've tried looking around at some of these tech support sites and haven't really found anything that's worked for me. I've tried using CCleaner to remove any temp files and clean the registry, and resetting internet settings in the command box, but still I get nothing.
Have completed a Power Cycle.The affected machine is a HP Elite m9150F desktop. The symptoms include the following:
- neither the LAN connection or the wireless connction will access the internet through Internet Explorer - microsoft email will not send and recieve - Steam will not connect - Norton 360 will connect to live update and download - taskbar icon shows LAN connection is OK - When I open Network and Sharing, the network map shows this pc is connected to internet through named network. - Local Area Connection Status show 197,816 bytes sent and 311,088 recieved.
We have 2 laptops connected to the same wireless network working perfectly. There is also another desktop (Dell 8400) with a LAN connection to the router working perfectly. The affected pc (HP m9150f) is also connected to router with a LAN connection. The D-link Dir-615 wireless router is connected to a Shaw Motorolla modem model SB5102. The HP m9150f stopped connecting a few days ago, other than that, it worked fine.how I managed to get 4 computers running on a network in the first place..
A few months ago, my family moved to a new apartment, and here we have AT&T U-verse internet connection and the router that AT&T provided; none of our computers have wired connections to it, because that would require stringing the network cables over doorways and/or across the ceiling. However, my parents' computers have had trouble getting internet access until they're warmed up - the system tray icons will indicate they have network connection, but when they try to visit an internet site (even Google), Firefox will say it can't find the server. Once one of their computers has been on for a while (I haven't timed it, but it seems like more than 5 minutes needed, and probably not more than 30), the internet works fine on that computer. I saw this for myself on my mom's computer this morning. I previously set DNS servers to 8.8.8.8 (Google's DNS) and 156.154.70.1 (DNSadvantage), but that apparently hasn't resolved the issue. Dad says he wasn't having trouble with this under Ubuntu, but now that I switched him to Windows 7, it has been happening on his computer as well.
In my room, I've got a desktop PC with a Rosewill RNX-N150HG usb wifi adapter, a Mac Mini (built-in wifi), a 2005 laptop PC (built-in wifi), and several gaming consoles, and haven't seen this issue on any of them.My mom's computer is running Windows XP and has a ECS 945 GCT-M motherboard connected to a Cisco wireless bridge as well as a Rosewill RNX-N150HG usb wifi adapter. My dad's computer was changed from Ubuntu to Windows 7 and has a motherboard that was pulled out of a Gateway GT5676 connected to the same wireless bridge (which we bought because we couldn't get Ubuntu drivers for the usb wifi adapter).I'm hesitant to get a powerline network adapter, because I think the pair I used for a while in our previous apartment was responsible for the death of a router (the router started only acting as a hub, and iirc wasn't accessible when I visited its ip address).
Have a 400N wireless router that has been working fine with several wireless devices on a small home network for about a year. Nothing has been changed but suddenly all of the wireless wireless devices dropped offline and none see the network signal in their search to reconnect. All of the indicator lights on the router look good and I have unplugged power and reconnected first the cable modem and then the router but still no signal. Logging into the router seems to show that it is working OK but there is apparently no air signal for the client devices to detect so only the wired devices are showing up. It's as if everything is working except the antenna function. Are there any suggestions short of uninstalling and reinstalling the whole set up and see what happens? I have taken my laptop to a nearby hotspot and confirmed that it is receiving other network signals fine so it has to be something to do with the router itself.
I use an Edimax 11n usb wireless lan utility to connect to my router. It gets 60% signal strength and 100% link quality. Either i get disconnected, limited access or no internet access statuses every other hour or not at all. Its intermittent which makes it impossible to explain to the internet provider. The main error that comes up when windows diagnoses is "DNS connection error". Now the internet provider has shown me how to manually set the router to use specific DNS's and that still did nothing.
I am unable to access the internet even though my wireless connection shows as active and strong. I tried the connection hard wired, but still no access. I ran a malware detector and removed two items, still no internet availability. What should I do?The trouble shooting device says "Firewall may be preventing your program from running". I have McAffee security system installed.
Since about 3 weeks ago my DSL has been getting totally random ping spikes, from under 40 to over 1500MS for minutes to hours on end. Nobody else is using my internet, I've verified this. There is nothing sucking up bandwidth on any connected device or computer, as far as I can tell through troubleshooting to the best of my ability. I tried switching to a Cisco X2000 modem/router combo and it did nothing, still totally random latency. Also, when I called AT&T about this, they didn't even know what ping was. They ran an upload/download speed test (which is still mostly consistent regardless of latency) and told me I was basically making the issue up.
We have a D-Link DI-524 wireless router that has had no problems until today. Our laptops (with Windows XP), iPods, and iPhones all show that there is an excellent wireless network connection (as usual), but none of the computers or devices will connect to the Internet. I tried resetting, rebooting, and unplugging the modem and router. The router and modem seem to be fine. When we disconnect the router and plug the laptop directly into modem, we have Internet connection (i.e., it's not the IP).
Recently lost the setup for my newly installed ea6500 for no apparent reason. had to restart from the ground.I have the latest upgrade but wonder about the differences between the linksys coonect to the online version vs stand along versions. DO nor like expensive software that losses its setup for no good reason.I also irritated that I am unable to access my cable box. I own it and cable box and lynkiys has no right to block me from it. 192.168.100.1. I was able to accessed it with my Belkin router and I should be able to access with this expensive ea6500 box!!
We NEED a non-gui version. The gui is great for simple networks and people who do not want to know anything about their network. it's ment to be use to deliver additional services to us at a cost. duplicated or generates random users with ip or mac addresses complicating the parental control.
I've run into an odd problem - I have connected two 2960s together with copper on FastEthernet interfaces, and STP on the new switch immediately puts that port into blocking mode. I don't understand why this would be, since there is only one connection between the two, in fact, there is only one connection at all on the switch that is blocking.
I'm having a little trouble connecting a new computer to my wireless network. I have a WRT400N router and I'm connecting an older computer to it. The computer runs off Windows XP and the router itself is a WUS854G. We can get the adapter to say that it is connected to the network, but the router will not assign it a new IP address or even acknowledge that it is connected on the MAC client list. We manually forced a new IP, which allowed the computer to connect (though, again, the router did not show that it had been connected to.) but despite the connection being "Excellent" we could not access the internet. Furthermore when we tried to refresh the connection the IP address reverted to the original setting.
I have some issue with internet connection and Router WRT54G. There is always "Local Connection" but no internet access. I checked that at two different laptops. One with Windows Vista and the other one with Windows XP. Both the same problem. There is a wireless connection with excellent signal strength but no internet access. I added a screen shut to see the Router setting. If more needed I will add more.
I lost my internet a few days ago out of the blue. I have been in contact with my internet provider with no success. None of the troubleshooting options have worked and my security software is giving me warnings; but is unable to scan or update. I've rebooted, done a system restore and reset my IP settings via DOS, which has not worked either. I have full connectivity, just can't identify the network and therefore can't get passed to the internet. I have Windows 7.
My bsnl wimax connection has stopped working on my laptop...IT WORKS ON MY FREINDS' LAPTOP. On my laptop (windows 7), in the taskbar, it shows connected and everything seems fine but i cant access any sites or download anything? Does this have to do with a bluetooth device i installed a few days back or some other issue.
I am trying to connect internet through Ethernet LAN .But I am unable to access internet. It says unidentified network with limited connectivity or local only access. But the same connection is working fine on other laptop. I checked the device manager and every looks working fine.In my ipconfig /all details, my Eternet LAN physical address shows all zeroes and has no default gateway address .Also the DNS servers address shows some alphabets instead of numbers.
Our ISP provider made our internet connection a dial up. Last time it automatically connects to internet without putting those username and password. So after they changed it only our server pc have internet. Others don't have. The technician from the isp provider keep telling that the switch(but he keeps telling us its a router dunno why) need to be configure but switches dont need to be configure right?
We've had no problems with our Internet before but yesterday I could only get local access connection. Neither my iPhone, laptop or home computer cud get any further than local connection on wireless.I'v tried the classic turnin it off and on (the router) and I'v tried connection with a cable but still gettin the same connection level! The router is a netgear if that means anything!
I have a DIR-655 set up as follows: [code] Lost Internet Access on my DAP-1522 on only my wireless laptop connection, but not other wireless nodes on the DAP-1522.I have most of my wireless nodes attached to the DIR-655, which is upstairs. Downstairs is where the DAP-1522 is located. There is a wired connection between the DIR-655 and DAP-1522. The DAP-1522 is being used as a Access Point. On this I have only three nodes that are wireless. My Smartphone, iPad and my laptop. There are also three nodes that are using the wired ports with no issue accessing the internet. The setup above have being working for over two years with no issue. Then three days ago my laptop connects to the DAP-1522, but has "No Internet Access." If I change my wireless connection to the DIR-655 on my laptop, then I do have internet connection. My Smartphone and iPad still are able to access the DAP-1522 and get the internet.
I have deleted my DHCP Reservation for only my laptop on the DIR-655. Wireless connection to the DAP-1522, looked at the DIR-655 and see that DHCP Reservation show the MAC of the laptop and I Reserve it. Still "No Internet Access." On the DAP-1522 it does show that my laptop is associated to this device. I cannot ping my local LAN IP Addresses , a website or Public IP Address only from the laptop. The DIR-655 shows a "Do Not Enter: Wireless system with MAC address 4025C2B97110 disconnected for reason: Received Deauthentication" with a connection to the DAP-1522, but shows "Do Not Enter: Wireless system with MAC address 4025C2B97110 secured and linked" with a connection to the DIR-655.
I usually acess internet on Wi-Fi, and now I have travelled, and got my laptop with me. The internet here is Local Are Connection, the one with the cable, and it says I am connected, 100 Mbps, but no internet access! I can't browse or open anything that has to do with the internet... However, It works perfectly fine on EVERY other laptop. I've searched a lot of places and I've been told to write commands like ipconfig/ all andd netsh int ip reset.log but when I do that I get "The following command was not found : int ip reset.log" I set the properties in TCP/IP to Automatically detect settings .. but nothing.
I have recently bought a new XPS 15Z Currently when I surf the internet I am unable to use the browsers ( IE9 or firefox ). I am able to use non-broswer related internet applications like STEAM, MSN or QQ with no issues in terms of speed or stability. But when I use my browsers to surf, I can have periodic moments when I cannot surf the internet, such as IE9 which says that I cannot connect to the internet due to some unknown error. But when I run diagnostics, it says that I do not have any errors. My adapter for my wired is the Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20). I have already contacted my ISP provider who have worked for with all the troubleshooting methods they can over the phone, and I trust that they are doing their best. But now it seems to me that the problem lies in my computer hardware or software and not in my router.
I need to know why I am losing internet connectivity like around nighttime, late. I keep losing internet on both IPv4 and IPv6! It both said "No Internet Access" Then later IPv6 said "No Network Access" That's the problem i am having on my personal laptop computer. I really am furious that I lost internet connection around 12:15, 12:30, 12:50, 1:30, 2:15, 2:30, and 3:30 A.M. i suddenly lost internet right there. And I heard the internet crew shuts down the internet system every nighttime and fixing it. I want to know why they need to fix it, how long will the repairs last ?
I have a Windows XP SP3 desktop with a NetGear WG111v2 USB wireless adapter and I get my internet connection from my Blackberry 8320 (I connect my BBerry device to my PC and start Blackberry Desktop Manager and choose to use internet access of my phone for my PC). I want to be able to make this internet connection available to other devices on the network wirelesly. I also have a nook ebook reader and a laptop which I would occassionaly like to connect to internet via the connection described above. How to go about making Blackberry internet connection shared accross the network? I tried Internet Connection Sharing Wizard, but I ended up with nothing to show up for.
To extend my wired ethernet I have purchased a WAP300N access point and connected it according to the instructions. I can see the AP from a wireless client and connect, but no IP number is provided to the client. The AP is connected to a router which has a DHCP server via wired connection (though a switch). The AP does it self get an IP number from the router but does not pass through DHCP requests from the clients.Occasionally an IP number is provided, but then there is no route to the LAN or the WAN on the other side of the AP.I have tried a whole lot of things to make it work (and been in the internet chat for two hours with a Linksys supporter, who could not make it work either).I have tried to set the IP number in the AP to static.I have tried to remove security (has to be WPA2 eventually, but for the sake of testing it has been removed)I have tried to factory resetI have tried to reinstall the firmware (the same version as the factory installed)etc.
