Ethernet Controller Shown As Being Present But Not Working Properly
Jun 12, 2012
I've been having some problems with my Ethernet connection lately.I unplugged my laptop from the Ethernet connection I had at my old place.At two different locales, I have tried to use an Ethernet connection in order to get better speed (the wireless at the first locale was non-existent and at the second it is extremely slow in my room). I have done so with two separate cables that I have tested on others' computers and found that they are perfectly fine. That, of course, leads me to believe that it is my computer and is either a hardware or software problem (here's hoping it's the latter).Anyway, my laptop is a Dell Inspiron 1720 (purchased in 2006). About a year ago, I updated to Windows 7 from the pre-installed Vista. Never had any problems (as I said, everything was fine up until about a week ago). The installed card is a Broadcom 440x 10/100 Integrated Controller. Everything under Device Manager indicates that the hardware is working properly and has all of its drivers installed, but nothing is working.I have tried to uninstall and re-install the drivers (albeit by allowing windows to find them automatically), but the result is the exact same.I have checked the port and found that there is no debris or obstructions. My computer hasn't been dropped or mishandled in any way.I'm currently being housed on the campus of Delta State University, which is why this appears, but here is the report: [code]
So I have an HP Pavilion dv9000 laptop with window 8 installed and when I try to connect to the internet I keep getting an error that says the "Ethernet" Adapter is not working properly. I used to be able to go on the internet and then my dad had my computer for a while and now it's not working.
I've just got a new AP 1250 series, and I was trying to configure the Radio for the 2.4Ghz spectrum using the interface dot11radio 0 and I've just noticed that this controller is not present so I cannot configure it so I wonder is it could be a HW problems as it looks to me or there is another way to enable this.
I never have an issue like this before so I want to first check with you before going back to our vendor.
Here is some of the details I get from the AP itself:
System image file is "flash:/c1250-k9w7-mx.124-10b.JDA3/c1250-k9w7-mx.124-10b.JDA3" ap02#sh controllers dot11Radio 0 ^% Invalid input detected at '^'
Using a small network (WAN) with three 1921 routers (IOS 15.1(T)) connected via E1 links. One host (industrial PC - core 2 due running Win XP Pro) connected to each router. The spare Gigabit Ethernet port on each router is bridged with the active one (so a portable management PC (laptop) can be plugged in there and communicate with the router and the industriual PC.
Multicast routing strategy between the routers is as per "Anycast - Static RP", with PIM sparse-mode enabled on all interfaces and sink RP defined on all three routers.
Problem occurs when a (IPV4) multicast application on one PC communicates with the others:
(a) IGMP V2 membersip reports etc. work correctly at the sender and at the other two PCs receiving the multicast stream
(b) Multicast routing on the WAN is working correctly; running Wireshark on the receiving PCs shows that multicast data is received on the expected group.
(c) But, there is an error in the Ethernet packets
i. The first packet's Ethernet header contains the correct destination MAC address 01:00:5E:aa:bb:cc where aa:bb:cc match with the last three octets of the mulicast group's address, and that packet is received OK by the listening multicast application
ii. However, subsequent packets' Ethernet headers have the wrong MAC address 01:00:5E:00:00:00 (the last three octets are all zeroes and these packets are discarded by Windows on the receiving PC and not seen by the multicast application.
Problem is related to the presence of integrated routing & bridging; if I delete the bridge virtual interface,disable bridging and give the two Gigabit Ethernet ports their own IP addresses, the multicast reception works correctly; all received multicast packets have te expected value on the destination MAC address (matching the group address)I have used the same integrated routing/bridging configuration successfully on Cisco 2611 and 2811 routers and there was no such issue with the multicast packets.Have I overlooked some subtle aspect of configuration in the 1921 router or have I uncovered a bug...?
For reference - snippets from router configuration scripts : In the non-working configuration (with Integrated Routing & Bridging) interface GigabitEthernet0/0 no ip address duplex auto speed auto
[code]....
In the working configuration all the bridging is gone and the two Gigabit Ethernet interfaces have a very plain & simple configuration in different subnets

Im having a problem with my wireless. My whole family is connented. to wireless. But when we all use it together it goes so slow. Like 4 some times only 2 people using it at the same time.
My WinXP Home PC won't connect properly (limited connectivity/no internet) via ethernet cable to my router (Belkin N150). Ipconfig /all shows the IP address as 169.254.117.71 but this is determined by an entry in the registry at HLMSYSTEMCurre....'DhcpIPAddress' - REG_SZ - 169.254.117.71. Also listed at 'IPAutoconfigurationAddress'. My laptop connects fine plugged into the same port getting it's IP automatically (192.168.2.2) and getting internet fine. I've tried adding a DWORD entry 'IPAutoconfigurationEnabled' = 0, also tried deleting the 2 values.Tried setting the IP manually to 192.168.2.6 - limited connectivity goes away but I get no internet connection from the router nor file sharing.
i had an extra network under my wireless networks that was just called "network" which was not connected to anything, but since i had this, on the bottom right of my screen where it normally showed the bars for the wireless connection, it had the bars grey with a red X on them, but my connection worked fine still.I am using windows 7 64x bit. I always use a wireless connection on my laptop.
I have 2 computers, One running Vista 32, Desktop.Another, Laptop, Win 7 64bit.Both computers have given Error 651 when using PPPoE wired connections, usually at the peak of the day.My ISP says that Error 651 is the problem, while I am starting to think its the amount of bandwidth their giving my neighborhood/home.Also, can that dosen't work,how to fix the overall problem of my Internet shutting off at peak hours?
when I couldnt turn on the wifi from the switch. It remained orange(which is its off state) and so I went to the device manager and the wifi adapter was shown there but with an exclamation mark. Showing the error "the device cannot be started(code 10)". So I uninstalled and rebooted, only to get the same error when it got reinstalled.
I have a Netgear CVD31T modem delivered by my internet provider. I can't change any settings on the modem. My connection speed is 30 gb up and 5 GB down.Until now I used a Linksys WRT54GV ver. 2 router to share my connection between my computers and NAS server and it worked ok. In speed tests I normally get approx 25 - 28 GB speed. To optain more speed on my LAN I want to buy a GB router. And here started my problems. First I tried a D-link DIR655, then a Netgear WNDR3700 and latest a Linksys E3000. I all 3 occations my WAN speed droped drasticaly down to between 3 - 5 GB speed, at under a ping test I have a loss of between 10 - 30 % and time on approx 50 ms.If I connect my PC directly to the modem or re-connect my old router it works perfect. I have tried to replace cables etc. etc.
Last night on the xbox 360 i was suddenly experiencing alot of lag on other peoples voices. i took no notice of it and the next day i went on my laptop and alot of websites wouldn't load properly.i can go on google,obviously this and my hotmail(after having to wait a long time for the hotmail to load), but others such as ebay will not load. I cannot even access my router settings by typing in my ip address, instead i get a message saying the page cannot be found. also i was disconnected from xbox live with the internet to xbox live part not working. Obviously the first thing i done was turn the router off and back on but it hasn't made any difference.

I bought a TP-Link TL-WR841N which i have managed to setup up properly, i am able to connect to the wireless and get internet access. However the minute i walk out of the room or a few meters away i am disconnected and i can't re-connect, i get the "windows cannot connect to TP-LINK" message. The signal strength in on excellent and i know it works because when i stand near it, it works perfect.I phoned TP-LINK technical support who were pretty useless and couldn't fix the problem.
ive been having some issues with my internet, i had an attack on my pc recently by some american orginization, ive reinstalled new windows on my pc, reset my modem, and nothign seems to work, i have too many tunnel adapters in cmd ip config i think, bell canada hooked up my internet lines and they actually joined two or more wires together and strung them up on the neighbours fence and mine and even wrapped it around a tree branch, god knows why they would even do that, maybe they think when the tree grows it will cost me money to fix it and theyll earn from thier mistakes instead of learn from them... anyway this is my ipconfig test results as explained in previous post from someone.Windows IP Configuration[CODE]
Some Trouble With My Wired Internet Connection,basically it worked somedays other days it cut off and didnt work for a few days,i phoned virgin media who sent me a new modem.Everything is set up and activated and it worked for about a day,now it has stopped working even though the computer says im connected,everytime i try internet explorer or firefox i get a white screen and every webpage i try fails,but if i bring up utorrent i can see that my internet is connected because it begins to download the ebooks
I recently replaced a Linksys wireless router with a Netgear wireless router(provided by Comcast) to the modem in my house. I used my HP Pavilion as the computer to run the setup disk and the wireless wizard to link the new router to the modem. I unplugged my HP from the router and proceeded to setup my computer on the wireless network.
When I check the strength sometimes it indicates it's good if I'm practically sitting on top of the router, this seems to eventually degrade to low until finally the connection drops.Repairing' with XP repair facility doesn't work. I can forget about getting a connection if I move further away from the router. At the moment I'm relying on using an ethernet cable snaking across the dining room, which isn't really practical with a toddler and a dog racing around. Recently a friend put a bigger HD in and before this it was working fine, so I suspect that it may be due to this. I think it's due to the wirless card in the laptop, as I have a number of other devices in the house which all work fine.
I have a an issue with one particular VPN user. They are using the built in Windows Vista client to connect to my ASA 5510.
All other users do not have an issue and i receive the following error at roughly the same time of day when the drop happens. Authentication is done by my AD Server which handles all logins.
I not familiar with the ASA 5510 product. I having trouble since last 24 hours and still cant find out the root cause yet. Here is my scenario, my network should be
WAN --- ASA5510 (FW) --- SERVER (192.168.1.0/24)
Now I face the problem, all the NAT static 1-to-1 is working OK. All my public IP can be ping from outside internet. But the problem happen when I try to telnet to port 80 on each server. I had try telnet from my PC to public IP 124.xxx.179 80, it's work fine, but failed on 124.xxx.180 80, then on 124.xxx.181 80, its work fine.
Then I do try on my colleague PC, in same network as mine, I face another case where the public IP 124.xxx.179 80 cannot be telnet, but it's ok for 124.xxx.180, then failed on 124.xxx.181 80.
FYI.. all our PC can ping to the Public IP and no packet lose.
The scenario is very weird, I cant find any other solution as had review my configuration few times.
check does my configuration is working perfectly or not.

I have one Flex WLC 7510 using software version 7.0.220, And all APs are 1131.
I have some sites with H-Reap, where H-Reap is configured properly.
The Access Points are set with AP Group. AP Group is configured properly too.
Each AP Group was configured for one site, and they was configured with 2 SSIDs. All sites has 2 differents SSIDs. During some basic tests, in one site with 9 APs, I saw:
1. When the Access Points are registred on WLC, all APs are working fine. All APs has your 2 SSID added on slot 0 (radio 0)
2. If I disable the link between WLC and Access Points, 7 access points delete SSIDs on your AP Groups and replace it with 16 SSIDs (SSIDs on Default Group) configured on WLC.
The Network icon in the notification area in the bottom right hand corner of my screen will almost always look like this:Quite frequently, though, I will get an exclamation mark inside a triangle with a message instead saying No internet access (I don't have a screenshot). If I give it a few seconds, usually never more than a minute (30 seconds on average it seems), it corrects itself and gives me back internet access.
I recently made an old router into a repeater by using DD-WRT. It seems to be working fine if I use LAN, but I cannot get WLAN to function properly. When I go to add a virtual interface and all the proper info, I all of a sudden cannot connect to the Internet. More specifically it seems to not assign me an IP address.
i am trying to connect wifi .i have two wifi hotspots. it just connects with one hotspot and if i try to to switch to other one it just shows windows was unable to connect. and it does not switch back to the previous connection. even it does no go to communicate with access point. directly shows widows was unable to connect.
I checked what she needed, updated her drivers for Ethernet and Wireless, and the Device Manager is stating that they are both working fine. (no ! or ? on them)When I plug in an ethernet cable it works fine. It gets connection pretty well through my BT Infinity modem.However the wireless will not pick up any connections at all. I attempted troubleshooting, and all it says, "Your network adapter is experiencing problems" etc.I thought that I may need to turn on Wireless Association on the modem, but that didn't work. My dads laptop is also a Windows 7 Laptop and that works fine and will bring up all connections in the area, including mine.
So I googled around, and I found that I may need to turn on a wireless switch. After looking around the laptop, I noticed two things. 1) There is no wireless switch, and 2) There is an orange light above the WIFI symbol.So I googled around a bit more, and found it might be turned off in the FN+f8 Flash card feature. At first I couldn't actually bring this up, so I reinstalled the flash card, and it began to work. It claims the wireless connection is "On".I am not sure what to do next. I have checked the services to make sure WLAN Autoconfig is on Automatic, and Started, and it is. I also tried disabling, then enabling both ethernet, and wireless connections, which did nothing.
I just installed windows xp pro 64bit and i am not able to use it im guessing because i need the correct driver, ive tried looking around but couldnt find anything. I also try it working with Windows 7 ultimate (64bit) and i could not get it working on that either.
Trying to set up a simple schedule for keeping the kids from staying up all night. I'd had this working on a Linksys WRT54G till it bit the dust. I just want it to block internet after midnight. My problem is that the schedule is triggering the block unpredictably.?
I have configured my CIsco 2911 router and there seems to be something wrong with my configuration regarding subinterface 0/0.102 The hosts on this subnetwork cant access the Internet and i cant spot the error.
Here is my running config on this matter.

I have a user using windows 7 64 bit. I tried vpnclient-winx64-msi-5.0.07.0290-k9.exe and vpnclient-winx64-msi-5.0.07.0440-k9.exe. Installation is fine. Connecting is fine. But no traffic goes through.The remote end cisco is 1811 VPN Server split tunnel. User get authenticated by Radius server.
After connected, user get the correct IP address. In router, sh crypto session, it has SA, etc. But sh ip route, can't find the Static route point back to the client IP like other connections.
At user end, windows show the IP address but no gateway. Windows route print shows the VPN network via gateway xxx.xxx.xxx.1 which is not available.Other 32bit users have no issues with VPN.
I am getting the below messages in my cisco asa 5520, during this time tunnel is down. just what to check whether the problem is at remote FW or with asa

I don't know if this matters but I am unable to get microsoft updates. I have 16 that continue trying to update but my computer will not allow.
Last year i installed nortor 360 gold edition onto my laptop and now it is telling me that it is not automatically protected against viruses and spyware, even though it has the latest update and no problems have been found on my laptop.
