Linksys AE2500 / A Device Attached To The System Is Not Functioning
Aug 7, 2011
A few weeks ago, I bought a Linksys AE2500 wireless adapter, and it's worked fine up until a few days ago. A few days ago, when I turned on my computer, I could not connect to the internet. I've tried uninstalling and reinstalling the drivers, but I am denied every time; the message I get is "A device attached to the system is not functioning".I've tried connecting to the internet with my other wireless box I used prior to getting the AE2500 and I cannot connect with that, either. The only way I can connect on this computer is with an ethernet cable.

I've verified that the router and the pc have the same time zone, daylight savings update specification and that they both showed the same time (00:56AM). But a file created on the attached USB device was timestamped 01:56AM (the date was correct).

How does a device attached to a Cisco IP Phone send data to the switch?a. As tagged (using the voice VLAN)b. As untaggedc. As tagged (using the data VLAN)d. As tagged (using the CoS value)The correct question is A in the book though it said that tagging is switch process PC's doesn't tag frames.

I've purchased a wmp600n pci adapter january this year and installed it with no problems and did not encoutner a single problem with it until today. I use windows 7 64bit.
I've just came back from a 3 week absence and turned on my computer for the first time since i left. I notice that I have no wireless connection. So i go to network connections and realize that my wireless adapter dosent even show up..only my lan card. So i check my device manager, and under network adapters, i can see my wireless adapter, but with an exclamation mark next to it. I check the properties, and under the status box, it gives me this message.Your computer's system firmware does not include enough information to properly configure and use this device. To use this device, contact your computer manufacturer to obtain a firmware or BIOS update. (Code 35).
So i do what it says, and flash my bios to the latest version. After the update, I check the device manager, and the error message is still there. I check my wireless adapter driver version and it is v3.0.2, which is the latest version according to the linksys driver download webpage. I've tried uninstalling and re-installing the adapter but no luck there. I also checked to see if maybe there was a problem with my pci slot and that was not the problem because I was able to use my older wireless adapter.

I have upgraded to prime LMS 4.2.2 (from 4.0.1) and can not perform system or device upgrade. Using wireshark I can see why. it looks like LMS is trying to go to this old web [URL] to get software. I believe this was fixed years ago in bug CSCto46927.
Can I reapply bug fix CSCto46927 on 4.2.3 or is there another fix?

My router was not functioning well so I decided it might be a good idea to reinstall the driver package via the admin upgrade page. Since then it doesn't work at all. The power light flashes constantly now.

I'm running Windows 7 64-bit with the very latest AE1000 driver (3.0.10.0). I have a Netgear WNDR3700 with dual band support. I replaced a D-Link DWA-556 PCIe 2.4 GHz card with this USB unit because I was seeing interference with my keyboard and mouse (Logitech Bluetooth). When the AE1000 works, I can consistently connect at 300 Mbps and the speed is great.Unfortunately, every so often, the connection to the internet drops and Windows 7 must do a wireless adapter reset in order to regain access to my network. During this time no other machines connected on the wireless network report any disruption and neither the 2.4 GHz or 5 GHz WiFi profiles are connectable with the AE1000.I've tried switching from the built-in USB 2.0 ports on my motherboard to the USB 3.0 daughtercard to no avail. I've tried uninstalling and reinstalling the driver. However, I started seeing this issue literally the day I installed this thing. The problem happens sometimes a few instances in an hour but then won't happen again for another few hours.In Event Viewer, I'm pretty consistently seeing:The TCP/IP NetBIOS Helper service was successfully sent a stop control. The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]

We have an Asterisk/FreePBX phone system located behind an ASA 5505 device where we are having problems with sip inspection.
We connect to three different phone providers, and things works as expected for 2 of the 3 providers,but for the last one (Draytel) we are having problems with sip inspection.
The key difference about the VoIP provider where we are having problems is that they are using differetn servers for the voice (RTP) traffic than the server we are registered with to establish SIP sessions.
sip inspection is configured with the default out of the box options.The problems we see are this:
1. For ingoing calls sip inspection does not open the required pinhole to allow the traffic to flow through. As a result we can not hear the voice of the calling party, but voice from our side is passed through ok.As a workaround we have added and ACE allowing traffic in the used UDP (RTP) range from this VoIP providers ip addresses to pass through the ASA, and with that in place incoming calls work.
2. Outgoing calls doesn't work because sip inspection doesn't kick in, and as a result of this we forward internal ip addresses in the SIP / SDP body to the VoIP provider. I'm not sure whether this is a consequence of sip inspection not kicking in for this provider, or a result of having added the ACE for an ip ragnge that covers the ip address we register with.
As stated above sip inspection does work as expected for two other providers where all traffic goes through a single server.We actually have had this working with ASA firmware 7.2(4), but as that version intermittently had a problem where sip inspection would stop working (fixable by power off/on or a clear command), then we decided to upgrade.

I recently moved into a new apartment and after receiving the code to the wifi that is included I started connecting all my devices. My Xbox 360 connected flawlessly. But my PC simply will not connect, I am running Windows 7 64bit with a Linksys AE2500 wireless adapter.
Quick note: I have checked that IPv4/IPv6 are set to automatically set to obtain IP Addressees and the DNS Server.

My network is a simple Linksys E3200 to broadband modem to Cox Cable ISP. When only one machine is attached, it works fine. When I add any other machine to the network, whether wired or wireless, PC or mac, the connection is dropped. I've updated my IOS, checked access settings, called my ISP. ISP says it has to be a setting in my router.

I have a Cisco Linksys AE2500 wireless adapter and a Cisco Linksys e2500 wireless router.
For the most part I seem to be able to connect to the internet with no problem. But whenever I stream video to my PS3, my phone, Kindle or when I start using a lot of bandwidth my internet drops and I get the "limited access" message with the yellow <!> symbol. It still shows full bars and excellent connection, yet cant get onto the internet?This happened with my PC at my old house, I forget was I did to fix it though? If it matters though I can connect fine to the internet from my Laptop and my other devices.

I've recently bought an AE2500 wireless adapter, and I've had problems setting it up, I've checked my port drivers versions and they're all up to date, I have looked over countless websites figuring out why it is doing this, my computer is a Windows Vista, and my last resort is formatting the computer, I've been here for countless hours trying to get this to work, when I run the disk with the adapter, it gets stuck at "Detecting Adapter" and ends up coming up with "Cannot find wireless adapter" or something really close to that. I've tried switching it to all of my USB ports, and nothing is working!

I just moved an older Windows XP Desktop /w Service Pack 3 from my parent's house over to mine after having my laptop fail on me. It was previously connected wirelessly at their house with a Microsoft MN-510 wireless adapter. When I got it up and running at my house, it was not picking up any networks with the MN-510. So I picked up a new AE2500 today, thinking that the ancient MN-510 may be the problem. Plugged it in, threw in the disc and voila, it started picking up Networks. The problem is, It is not connecting to my Network. The router is a Motorola SBG901. I have already disabled the security on the router and made sure that the MAC Filtering is disabled, but it is still not connecting. There has been no other issues with connecting any of our other devices.

Yesterday I bought a linksys AE2500 usb network adapter. So I set it up on the computer downstairs from the router, roughly 30 ft distance. There is a desktop running a linksys pci card directly next to it. So I fire the computer up it see's the network but it won't connect to it. Then I take the computer up to the room the router is in and it connects. The range on the adapter says 300 ft and I do realize that there are walls and other obstructions that cause that number to fall but I find it hard to believe that the adapter is out of range but I can't think of anything else to explain it.

I'm running Windows 7 Home Premium (64 bit) connected to a Linksys WRT610N Router. I have attached a 320GB USB 5400 rpm hard drive to the router as NAS storage.The router is running 2.00.01 build 15 firmware. I get frequent drop-outs when transferring large files. Tonight I've been trying to transfer a 4.36GB file to the drive from my PC. I've tried several times. At exactly the same time, with about 377MB to transfer I get a message saying 'There is a problem accessing Z: make sure you are connected to the network and try again'.

I have a small home LAN of four hard-wired PCs and two iPads and two notebooks which are connected by wireless. At the heart of it all is a Linksys X3000 wireless router. Any of the four PCs that are hard wired to the X3000 have no problems talking to each other but none of the wireless-attached iPads or notebooks are able to see any other machine on the network. All machines are able to access the Internet.

I'm starting this thread because I can't get my new Linksys AE2500 wireless use adapter to connect to my new Linksys X2000 ADSL modem. I purchased both of these devices because my old 2wire modem kept dropping the wifi signal and I had to keep turning off and on the modem in order to get the wifi signal back. Now my problem is that I can't connect my AE2500 adapter to the x2000 modem at all, heck I can't connect any wifi enabled device to the modem even though the SSID and password is correct. The adapter finds the network but it can't connect to it at all. The x2000 modem works perfectly since I can use the internet if I connect my computer to it via Ethernet cable but unfortunately I have my desktop in my room and the modem is in the living room so connecting using an Ethernet cable really isn't an option. I tried using my old 2wire modem to see if it would connect to that modem and it did as a matter of fact and the speeds were good but as of late, the speeds have been horrible and the signal drops every few minutes. I get 1 bar in the network status and speed of 1.0 Mbps. Here is a picture for reference:
The problem only persists when using wifi though because when connected to the 2wire modem, the speeds are fast. Range isn't really a problem because im like 10 feet away from the router so I'm not sure what's causing that problem. I assume it's the modem being that its about 7 years old so I would really like to get my x2000 working to see if it's better than my old 2 wire. I'm currently connected to my old 2wire modem via my AE2500 wireless usb adapter as that's the only way I can use the internet.Here's my info:

I recently upgraded my router to the Linksys E4200 and setup a 40MHz connection using Channels 44+48 of the 5Ghz spectrum. This works really well on my wife's Lenovo T420 w/Centrino 2x2 and Windows 7. I get over 100Mbit sustained performing CIFS file transfers from my file server. My SSID for 5Ghz is different from 2.4 so I can easily verify which one I'm connected to.
I wanted to do the same on my laptop which is a bit older (Lenovo T410) and only supported 2.4Ghz. So I bought the new Cisco AE2500 802.11n USB adapter and plugged it into a USB2.0 slot (I believe all slots are USB 2.0 on this laptop). I'm using the latest driver from the Cisco website.
Windows XP reports a connection speed of "300Mbit" just like on the my wife's laptop -- but when I do the same CIFS file transfer my transfer rate is "stuck" at 39mbit download (13% of 300) and for uploads I'm getting 16-17% of 300 (approx 48Mbit).
I've tried fiddling with all manner of advanced settings in the Windows driver for the NIC with no avail. No matter what, it's like I'm capped at exactly 39 Mbit.
I tried reviewing the specs of the AE2500 and it says it has two antenna's per band. I assumed this meant it was 2x2? Is this not the case. Is it 1x1? Could this explain it? Or, does it matter which 5Ghz channels I use -- from the AE2500 spec sheet it seemed like it might not support all 5Ghz frequencies?
While 39Mbit is better than the 17-20Mbit I was getting on 802.11g, given how well my wife's laptop works using the Intel NIC it seems something is lacking with the AE2500 or its driver.

I have tried numerous times to install the disk and the adapter, but it always says it cannot locate the adapter. I know that the ports (I have tried them all) are working properly because they have been in use. I tried the chat. He suggested I call the 1-800 number. I don't have time to wait on hold forever, which I did anyway until I finally hung up.
