Linksys Wireless Router :: EA4500 - Unknown Device On Network
Apr 9, 2012
I recently purchased a Linksys EA4500 Dual-Band N900 Router with Gigabit and USB. Everything set up great with no problems and after a day or 2 I managed to get all home devices connected (2 laptops, 2 printers, an iphone, 1 tv, 1 blu-ray, an old desktop, and a tablet). Everything was connected right and working and I installed the Linksys app on my iPhone which let me see what devices were connected and all that. Well, last night, an unknown device showed up as a connected device. It's labeled as: android_(insert string of characters) and has a MAC address. I've tried and tried to identify what this device is and I can't. Everything else on our network is still showing up independently of that device. I'm worried that someone using our connection and possibly putting our device security at risk. What can I do to A) try to identify what the device is and B) if it is an intruder, block it's access.

I just purchased a Linksys EA 4500.I set up the wifi properly, with laptops, tablets, smartphones and printer. The wifi network worked fine for a couple of days.But now one of the laptop "refuses" to see the Linksys wifi network. The other devices are still connected and running regularly.
The notebook that does not connect anymore is an ACER 5740DG with an Atheros Network adapter and Windows 7 installed. This notebook is otherwise running fine.At the beginning it was connecting ok and we never had any problem at all with the previous router Belkin_N+_7991AC, that I changed just for speed.
Now the Linksys network is simply not visible to such notebook in the "Available Connections List" that I get clicking on the WiFi icon in the bottom right, while a number of other wifi networks (not mine) are clearly visible. Of course I restarted the notebook properly. For one time I got the visibility of the Linksys, I entered the password and then it was not possible to see the network anymore.No error message from Smart WiFi software.

I have the WRT400N router with the latest firmware. Recently I have noticed a device in my DHCP that I do not recognize. It is not device I own (believe me, I have racked my brain and confirmed) as it shows as an Acer pc. I cannot ping the IP address however. I have rebooted my router several times thinking maybe it's a former connected device but saved in memory but it keeps coming back. I am thinking possibly it is someone hi-jacking my Internet, but not sure. I am using WEP security but it shows a LAN connection which is strange for a wireless device. The only hard wired pc is my HP.

I have an EA4500 and am using Cisco Connect Cloud software. Its working mostly fine except that I have one device on the network that will not show up in the device list. This is not an issue in itself and normally I would ignore (although it used to show up when I forst got the router) however..
The device is a WDTVLive media unit and required access to windows shares on a media server. Now the WDTVLive device is server an ip address by the router and is available from everywhere on my network but every couple of days it loses the capacity to search windows shares.
I know what you are thinking and I initially thought the same, this is an issue with the WDTVLive box. However one day I spent a few hours trying to resolve (Am an IT Consultant and know a little about networks) and found that I could not fix the issue. I then rebooted the router and it started working. I have since confirmed that every time it breaks I have to reboot the router.

Since i got sky broadband it's always been running super slow, the amount of times i have called them is ridiculous. So i have just been looking around on the sky address to see if i can fix it and in my Attached devices i have, the pc, an ipod touch and an unknown device. I'm wondering if this has anything to do with the slow speeds and maybe it's somehow 'stealing' my broadband. I've read a previous post of the same type but that wasnt for sky. i ran the ipconfig/all into CMD

I have several devices connected to my Linksys EA4500. Two of them are my Apple Mac Pro and my Logitech Squeezebox Radio. For some reason, in 'Device List', my Apple Mac Pro has the manufacturer 'Logitech' and the model 'Squeezebox Radio'. As for my Logitech Squeezebox Radio, it doesn't have a manufacturer nor a model. It appears that there is a mix up with these two devices. I have cross checked the IP addresses and MAC addresses displayed in Cisco Connect Cloud with those displayed on the devices and they match - so it's not a case of mixed up names. Could this be an issue with Cisco Connect Cloud?

I am using a EA4500 and use Linksys Smart Wi-Fi to manage the device. In the household we have multiple Apple i devices. Somehow the Linksys Smart Wi-Fi combined two separte i devices (iPhone 5 and a 4th generation iTouch) to one user.The devices actually have different names, but the Smart Wi-Fi is combining them into one device. So I can't use Parental Controls on one of the devices.

It may be a coincidence but my Broadcom Network Adapter 802.11g stopped working after trying to fix 'unknown device' in Device Manager (It was working perfectly before this).OS: Windows 7 Starter on 'BenQ Joybook Lite U105'.I tried the Windows Network trouble shooter and it didn't work (saying there may be a problem with the driver. I uninstalled the driver and re-installed it (including a possibly newer one) and it didn't work. Within 'Network Connections" the Broadcom wireless adapter is shown as 'disabled' I R-clicked to enable it, a window popped up saying it was enabled but it still showed as being disabled. My feeling is that something is preventing it from being enabled, logically, I would guess. Also went to 'Component Services' and ether started or restarted everything with the word network on it still no luck..My Google search on an other pc , now on day 3, couldn't find anything. (BTW the 'unknown device' which according to the icon, seems to be the joybook itself, is still not fixed and still listed as 'unknown device').

In the settings menu, there is no l2tp in which it was possible to configure a local address of the router. It should be: 10.155.41.41There is an option only for VPN server setup(10.255.255.254), but where it takes a local address that my provder has gave me? - it is not clear. At the same time in the status of the router receives a DNS correctly and the second address embarass me little bet DNS should be:
1) 80.252.130.253
2) 80 252.130.254
first dns is correct, and second one looks like: 80.252.45.86Maybe he does not take a local setting of ip adress via DHCP?

I just installed my EA4500 router and it was amazingly simple. My only question is it shows two wireless connections available: The secured one I set up and the another network with the same name that says "guest" and is NOT secured. Is there a way to either disable the unsecured guest network or to secure the guest network?

just bought the EA4500 new, setup the router with computer plug-in RJ45, after I change my network network to "LinksysOne", I can connect to the network wireless. But when I connect it with hard wire/RJ45, it shows "cisco27205", but I cannot see "cisco27205" with wifi, neither with RJ45 connection cannot see "LinksysOne". Why this happen? is this normal?

I have got a Cisco EA4500 recently installed and it's great. I was very excited about the USB part as I attached a WD hdd to share the media. All good apart for two issues for which I can't seem to find a solution:
1. Transfer speed: Playing a movie over wi fi from the attached HDD works fine. However, if I try to copy the avi file from my mac to the attached hdd or vice versa the transfer speed is around 1 - 2 Mb / sec. How I can improve the speed?
2. Can't write files on the HTF+ partition
My hdd has two partitions: 1 x NTFS and 1 x HTF+.When I try to copy a movie from my mac through the Wi Fi on the HDD it would not let me on the HTF+ partition although I logged it as an Admin. I say I don't have the priviledges. However, on the NTFS partition works fine. Full r/w priviledges seem to work only on NTFS. Is there an issue with mac partitions?

I noticed a bug with the EA4500 (could possibly be all EA series) router that linux machines cannot see network share with the smart firmware. Just right after I upgrade to the smart firmware, all my linux machines cannot see any network shares at all. I downgrade to the classic firmware, every thing works like a charm.

I want to setup a Linksys EA4500 in bridge mode behind my separate firewall to access the domain LAN. I'd also like to supply a wireless guest network for clients. In bridge mode the EA4500 doesn't seem to offer a separate guest network. Is there any solution other than adding another Wireless router just to serve up the Wireless Guest Network?

I have had several Linksys and Cisco routers in the past, and I'm a network engineer. My E3000 died after only 18 months so I had to run down and buy a new router, thus the EA4500.
I use the manual way to configure all my network gear. Nothing on my network changed, except the router replacement.If I leave the router default address at the 192 range, DHCP will issue a IP address. However, I do not use that range and after cdhanging the range, setting my start IP address, etc, I save everything and even tried rebooting the router to no avail. The router will not issue a DHCP addrss if you change the default range.
I can manually configure my clients with a static IP and all is good, no issues at all. I just can't get DHCP to work. My E3000 was configured exactly the same way and worked just fine, well up until two days ago.I have tried upgrading to the latest router firmware, so I'm not on 2.0.37 and I did set the router back to Factory Defaults, rebooted, then configured it, and still no DCHP.

I've recently purchased a Linksys EA4500 router. I've got home, I've used the installation guide CD thingy, connected 3 of my laptops wirelessly, no issue there.However when I tried to connect my 4th laptop problems came along. The problem I was dealing with was that I couldn't connect to the router. I mean I could see the network name appearing in the list, but when I tried to connect the network would just dissapear from the list, not connect, and wouldn't back on the list unless I've reset the laptop. Anyhow I've ignored that computer because I thought it was two years old and it might have had a wireless network adaptor issue, although it was conneting with no problem to my former router D-Link DIR 365.Anyway, just yesterday I've purchesed a brand new netbook (Evolio U9) and it doesn't see my router, although it sees all the other connection availables (my neighbors' wirless networks), I even connected to one of them just to test if anything was wrong with the netbook.
I also have problems when trying to connect with an Iphone 4. Well, it does connect, but the connection to the iphone just goes on and off making it impossible to use. It's really strange that all the 3 Iphones in my home have no issue connecting, not even my Glaxy S3, nor any of the Smart Tvs, nor the printer.Does the router have any number of limited connections available? The router configuration is the ones done from the CD. I've only assign a SSID and a WPA password.Please note that all the computers above are GENIUNE Windows

My EA4500 router seems to drop mine and my wife's iPhone wifi connection at what appears to be the edge of my router's range. When we come back in range, our iPhone's intermittently give the error "Unable to join network.". And we're stuck in that mode. When I check the Devices menu in the CCC interface, I notice the iPhone device is configured and still online. However the "x" box to delete the device is greyed out because it's online. So how do I get out of this state and have my iPhone connect

I purchased this Router about 2 weeks ago as a phased upgrade of our Home Network, primarily to enhance media streaming. It has the latest firmware preinstalled from the factory. Prior to the purchase and installation of the EA4500 Router I replaced my old Motorola SurfBoard SB6120 DOCSIS 3.0 Cable Modem with a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem. My old Linksys E2000 Router worked perfectly with the SB6141, with the exception that the E2000 wasn’t IPv6 enabled, but does have 10/100/1000Base-T Ethernet (RJ-45) and Internet ports.
The EA4500 has been installed for about 10 days and seems to have improved local network speeds and I don’t seem to be having any Internet connectivity issues. However, there are some disturbing issues with the EA4500 and the AE3000 I purchased. There are 11 devices connected through the Router; a Dell Desktop (wireless with the AE3000), a Dell Desktop (Ethernet), a Dell Laptop (wireless), 2 Canon Printers (1 Ethernet and 1 Wireless), 2 Western Digital 1TB MyBookLive Network Drives (both Ethernet), a WD TV Live Streaming Media Player (wireless), an Apple TV media player (wireless), an iPad (wireless), and an Android Smartphone (wireless).
Issue 1 – The Linksys Smart Wi-Fi interface appears to be unreliable at times!!! I’ve read about this problem here on the Community involving the EA6500, so I don’t know if this is a Linksys Server issue, as suggested in a few responses, or a bug in the Router firmware, or defective hardware. However, when the interface locks up, it can’t be accessed from a wireless or wired connection. Usually, powering down the Router and then powering it back up and restart will allow it to function again. However, at times before the interface completely locks up it shows either just a white screen or the security screen will show no firewall features enabled. This is a little scary, so I’ll do a complete reset and setup; this is becoming a pain in the rear! Is there any hope for this being fixed, in this Router, not the next generation?
Issue 2 - All of my network devices show up in the Router’s Device List. Except for the Apple devices they also show up, when they are online, in Windows 7 Explorer under Network and when you click on Network they are correctly displayed as Computers, Media Devices, Network Infrastructure, or Storage. However, when you click on “Open Network and Sharing Center” and then click on “See Full Map”; it fails with the response “Windows cannot create the network map. Responses from other devices on the network are delayed or there is an incompatible router on the network”; no device map is shown. When I follow the link for more information, the only thing that stands out is “A device on the network, such as a hub or switch, is not working properly or is not compatible with the Link Layer Topology Discovery (LLTD) protocol, which Windows uses to create the map. To fix this problem, disable the device, turn it off, or remove it from your network”. All of my network devices showed up on the Network Map with the old E2000. This issue is the same on all of my computers, either wired or wireless.
I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.

I have successfully set up a guest network on my EA4500. Guest laptop associates with guest SSID just fine. Then via IE, it gets prompted for the guest password, which is entered and accepted just fine. At this point guest laptop is on the network.
BUT... at some point the guest laptop will need to reauthenticate (I don't know what the timeout is, but maybe one or two days?). Anyway, it's at this point that IE presents the guest network login page. But now after typing in the password, "enter" or clicking on the button does nothing. It looks like the guest web page doesn't get loaded properly or completely, so the reauthentication can't complete, therefore can't get to the internet. So, while in this state, I've also tried Firefox and Chrome, and same thing, no action when trying to submit the guest password. Tried rebooting guest laptop, and still same problem. Only thing I've found so far that works is to reboot the router. So I'm guessing there's a problem with the guest/web server on the router?? It's a real pain to have to reboot the router every day or two, when I've had other Linksys routers run for months without having to touch them.
I was running CCC 2.1.38 when I first noticed the problem. Since then I've downgraded to Classic 2.0.37, but it seems I still have the same problem. Again, I can connect & authenticate just fine initially, but when reprompted after some period of time, it doesn't work.
I've tried contacting Cisco support, but it looks like I'm at 91 days since purchase and thus outside of my 90-day complimentary support, so they happily provided me with the premium support options just to have the honor of talking with them. Guess I shouldn't have spent so much time trying to figure this out myself.

I'm trying map the USB hard drive connected to my EA4500 router as a network drive in Windows 7, and it works perfectly until I enable secure folder access on the router.
After enabling secure folder access, and not changing any other settings on the router I first unmount the drive since it was set up without credentials and doesn't work that way any more. When I try to remap the drive I use the same address, but select "Connect using different credentials" When it prompts me for the log in info I try using the router admin account, but it fails to connect. Windows network diagnostics tells me the device refused the connection. I proceeded to set up an account on the router under the folder access settings with the same username, and password I use on my computer, and tried to connect it without checking "Connect using different credentials" (And typing them in manually if that matters) with the same results.
Even with secure folder access enabled I can still reach the drive just fine by typing "ftp://192.168.1.1/" into file explorer. It prompts me for a username and password, I put in the admin credentials, and I'm in. Even the account I created with the same username/password as my computer works this way.
After disabling secure folder access everything works perfectly fine again... I would MUCH rather do this with it though.
Following these directions: [URL] When clicking the browse button the router shows up when secure folder access is disabled, but does not after it is enabled. I've looked through my windows sharing settings, and haven't noticed anything that should cause problems, pretty much everything is enabled. I've also tried turning off my firewall with no success.

I have a Linksys EA4500 setup on my corporate network for wireless access. I have enabled the guest network and from all I can tell it's on a seperate subnet from my internal network like it should be. 192.168.x.x My internal is on a 10.x.x.x network. I conenct to the guest network using a laptop and I'm prompted for a password to get to the internet, which I like. The one issue I'm seeing is when I'm connected to the guest network I can still do an RDP session to internal resources. How is this possible if the guest network is on a seperate subnet?I take a laptop which has not been joined to my domain, connect to the guest ssid, and then open an RPD session and enter an IP address for an internal server and it connects. Is there a setting to keep this from happening

My desktop's internet connection is acting up. It's always worked fine, then all of a sudden it has stopped. I can still access MSN messenger and Paltalk, perfectly fine, and it is showing that I have an internet connection. However, when I open any of my browser windows, it cannot access the internet. My laptop and ipod are connecting fine on the wireless. I have my ethernet cable from the desktop plugged into the router, which is plugged into the modem. I CAN force the connection to work by 'talking' to the modem (using the IP address) and doing a disconnect and reconnect. This lasts for a little while, then it stops again. When I do my network map, it shows an 'unknown device' where the modem is supposed to be. When I disconnect and reconnect the modem, it changes from 'unknown device' to 'switch'.

We had a new linux server installed at a remote office yesterday, unfortunately the guy installing the server forgot to change the IP addresses, doh. It's plugged into a C877 and I can see the port is up/up and I see the mac address using 'sh mac-address-table'. The ip address on the server is unknown but it's unlikely to be in the correct subnet for the vlan it's attached to.
Is there a way I can add an arp entry manually to the router, then ssh to the server and correct the ip address? Or is there some other way to establish the IP address of the server? It's gonna be a pain to revisit the office and there's no one there that can get into the server room to do anything from the console.

installed the E1000 router that AT&T provides with U-verse DSL. All works fine except that the device name that appears under "Network Infrastructure" in Windows 7 shows the original default name that Cisco assigned instead of the name I chose. It does not affect operation or performance but looks oddball. I don't see how it can be changed.
