Linksys Wireless Router :: E4200v2 Wireless Connection Won't Connect
Mar 18, 2012
I have a E4200v2 and im getting wireless connection issues. I have updated to the lastest firmware and have checked all my wireless settings. I dont use usb storeage. I have 1 laptop using 5G, my iphone using 2G and my wife mac using also 2G.. the problem is that, once we stop using the 2G connection (leave it overnight), it just dies the next day.. it wont connect, i double check the password and it wont connect. But the 5G connection is fine.. Do i have a break E4200v2? or anyway of fixing this?

I recently changed my wirless router from the E4200 to the E4200v2. As far as I know, I have the same settings on the E4200v2 as I did on the E4200. My PS3 will not connect to my wireless network via the E4200v2. I even retyped in my network information (SSID and password) onto the PS3. Still "no joy." Any issue with the E4200v2 and the PS3?

I have a couple incredibly annoying problems with my E4200v2. I have one Win7 laptop that connects wirelessly and has been slowed to a CRAWL connected to this new router.3 of the 4 Android powered devices I have experience random and unexplained drops in Internet access. It seems they stay connected to the router itself but they lose Internet. Happens at random times and intervals.

I'm having trouble maintaining a 6rd connection with E4200v2 and the 6rd tunnel. When the 6rd is first setup, IPv6 works perfectly on all my devices. But that only lasts for a few hours. My windows xp computers and iphone cannot get an IPv6 connection/address after a few hours. And then hours turn to days with no IPv6 connection. The router says it's got an IPv6 address but I'm not able to connect any devices to any ipv6 sites and/or ipv6 test sites (ipv6 tests fail). IPv4 always works. There's no problem with IPv4.
So I'm wondering if Cisco tested these routers for a couple hours but never did any long term tests? Or maybe the problem is with AT&T? It would be too big of a coincidence for it to happen on several windows computers and apple devices at the same time to be a device problem. It's failed the IPv6 tests with friend's ipads and Windows 7 computers also.This issue has occurred on all versions of cloud and classic firmware including the latest 2.1.39.145204. The only way to get IPv6 back working again is to power cycle the DSL modem (in bridge mode) and E4200v2. It doesn't matter if the 6rd is configured to automatic or manual using AT&T's published BR settings. Same result. IPv6 lasts for a few hours.And it doesn't matter if the modem is in bridge mode, or if I configure Lan-to-Wan or L-W with IP pass through.....same result.

I've bought my E4200v2 via eBay, because original Cisco store doesn't ship to my country (Israel).My first unit was... defective, I think I wrote about the issue on this forum a while ago.It had connection troubles, always in a dead loop, saying "Connecting..." one to 100 times it managed to connect, and suffered slow internet connection speed, where all speedtests gave me 60% of my actual internet speed.Which is 30mbit.I'm sure about my ISP, it uses next.gen technology, they have their own underwater optic cables. Without Cisco router, only dialer, I get 100% of my internet speed, or with another router as well.I decided to RMA my e4200v2.
Out of context question: Why there's no option to specify server name instead of server IP? our ISP uses domain name for connection, rather than IP address, as they have a lot and a load balancer above 'em.Now, to the original issue.Refund is no option, RMA again is no option, too much time and money.Maybe there is a solution? It just can't be the reality, that two out of two units are not working. I heard this router is very good. And I heard the v1 is working very well in Israel. so It can't be our country that is the problem.By the way, I've called my ISP and they've switched me to MPLS connection for a try, so in a router you just switch to "Automatic configuration - DHCP" and it pulls IP, DNS servers and connected to the internet, but was hooooribly slow.
So I'm back to dialer. the main still is the "Connecting..." loop, sometimes says "Connected" for a second, and then connecting again... It manages to pull DNS addresses though, but never the IP and never managed to stay connected.All the connection configs are very basic, you know it. Server IP, username, password, keep-alive, MTU (I've tried auto, and a ton of other combinations recommented by our ISP or Cisco).My latest idea was to film how I burn it or throw a rock at it and send to Cisco the video, but that's kinda too much, it's too early for such decisions, especially when already $300 were spent.

I haven't changed anything apart from the SSID names so I can choose which device has access to which band 2.4 or 5ghz.I've come across an issue with the wireless and it drops connection randomly. I have to then disable and enable wireless adaptor on my laptop to connect again.I have read reports of allot of people having this issue however the majority of the issues were over a year ago (2011). Am I to assume this issue was resolved with a firmware upgrade somewhere which I may of missed? My current firmware is 2.1.38.138880. Is this the most up to date?

I've had this E4200v2 for a while now, and it's been giving me a headache because even at default wireless setting with the passphrase, it literally won't ever connect from a linksys wireless adapter using the mixed WPA2 Personal or the 'EasyConnect' button feature or the PIN, with both side's fireware updated to the latest. There is no issue connecting to the router as long as the security is off. I've tried other form of encryption to no luck.

I was able to connect to my 5ghz and 2.4ghz networks just fine. Now today I get a message that the connection timed out whenever I try and connect to the 5ghz. I have done a 30/30/30 reset, and still no joy. The one thing I haven't done yet is a 30/30/30 with a configuration from scratch. I will probably try that later. I've done the usual things like change the channel and all that, still no go. Other things I've done, change the network name, change the MTU, restart my machine. However, this is happening on other devices as well. The 2.4ghz network, solid as a rock.

So now I have a good connection with my secondary router going to my acer a500 android tablet, my laptop, and panasonic viera tv. All is good thus far. However, I cannot connect my Samsun BD-C7900 Blu Ray. What is really wierd is that the 5 Ghz and 2.4 Ghz have two different names on my router (cause that is what the cisco support tech told me to do- give them separate names) but on the Samsung BD-C7900 - it shows that there are two signals coming in but with the same name! When i tried to connect i get an error message. Keep in mind my E4200 v2 is secondary router connected to fios actiontec.

I have an E4200v2 configured with an n-only 5GHz network and a mixed 2.4GHz network. Our MacBooks and iPad connect to the 5GHz network, and everything else (iPhones, TVs, etc) connect to the 2.4GHz network. If I disable "WMM" on the QoS screen, nothing can connect to the 5GHz network. Those same devices can connect to the 2.4GHz network, but not the 5GHz. The MacBooks, for example, get a connection timeout error, and the iPad just says "cannot connect." This doesn't seem quite right. I don't absolutely need to disable WMM, but I wanted to make sure that normal WiFi Internet traffic didn't get priority over local wired Mac->AppleTV streaming or voice calls from our wired Vonage box.

I recently puchased a new E4200v2 router and one of the devices that I have on my network is a Level1 WCS-2040 wireless network camera. My old router was a Netgear WPN-824. I was able to (and I'm still able to) connect the camera to the Netgear router with WPA-PSK but not to the new E4200v2. The only way for me to connect it to the new router is with WEP, which I obviously do not want.
I'm at a loss for what the problem is because the setup is easily done. I'm thinking it's an issue with the E4200v2 but I'm not sure what... hoping that the issue could be resolved in the next revision of the firmware. I've tried WPA2/WPA Mixed Mode, WPA Personal (which I understand is the same thing as WPA-PSK) and WEP. The camera supports WEP and WPA-PSK. When I have the camera configured with WPA-PSK it simply isn't connecting to the E4200v2, only the old netgear.
See screenshots below:
Netgear router wireless config:
Netgear router connected devices (shows laptop and wirelss camera):
IP Camera config while connected to old router:
IP Camera working on old network:
E4200v2 wireless status:
IP Camera config while connected to E4200v2 router (via wired connection, not wireless):
When the wired connection is removed from the camera and powercycled, the E4200v2 does not list the camera as a connected device. I've power cycled everything, multiple times and tried everything I know of. What could be the problem? Note that the MAC address for the camera is the same for both wired and wireless adapters. And no, Password1 is not my default password... just what I was testing with for the purpose of screenshots.

I'm having an intermittent issue with my E4200v2 router. Frequently I will be using a device on the wireless network, and it will be unable to reach the internet. Normally I would assume this was a problem with the cable modem, but disconnecting from and reconnecting to the router often fixes the problem.

this topic has been discussed under the v1 software and marked as solved yet it has not been. Has anyone attempted with version 2 software and been able to connect after the arp was flushed?

I will soon upgrade my wireless network from a WRT610N to an E4200v2. At setup of the router, I assume I'll be able to change the SSID of the E4200v2 and I plan to keep the same SSID as on my old router. With the same SSID as currently seen by the devices on my network

I have a synology DS411 and a ATV2.DS411 is always downloading from internet,normally the download' bandwidth of DS411 is around 2MB/s.In my old netgear 3800,i just need to active WMM and add a port OQS that the port connection DS411 is low.Then when I watch stream video from internet on my ATV2.I can see the DS411's bandwidth will be reduced automatic.I replaced 3800 with E4200v2 some days before,and I have done the same config ,turn WMM ,set ATV MAC to highest and DS411 MAC to lowest. But when I watch ATV2,DS411's bandwidth seems not be reduced,so I cant get the smooth video Its very bad.

We have the Linksys E4200v2 router. We have two servers on our network that we want to access remotely (from outside). We have two Static IPs from our ISP. We currently utilize one of those IPs to access one of the servers-no problem. How can we utilize the second IP to access the second server?

I have a static IP on the ATA (Linksys PAP-2T) ...the router will only pick it up occasionally...most times it does not. The ATA is on and working (I can call in/out) but I can't see how the router can't find/see it. I have added the ATA to the DHCP reseve list but still nothing. I have the port fowarded for the ATA but when I go to canyouseeme.org it comes up as "Connection timed out"...becuase I think it can't see the ATA behind the Router.

On the D-Link it was easy, I can see who is connected to which radio.But I can't figure out how to see who is connected to WiFi on hte E4200?I run several access points in my house, and I need to make sure htey are all working.If I can't see who, if any, is connected, I have no idea if WiFi on the E4200 is working.

V2.0.26.124551 is now available. I did the online upgrade and it took just a couple of minutes including the reboot. The firmware is not available as a download yet for manual install. This firmware is dated 11/14/11 so it doesn't appear to correct the Port 53 issue reported earlier.Release Date: Nov 14, 2011 Firmware version: v2.0.26 (Build 124551) - Support for the WAN L2TP and PPTP protocols

My ISP dynamicly assigns IP's so I have my New E4200V2 set up as Automatic Configuration DHCP. I want to be ablt to use a specific DNS server rather than the one issues by my ISP.No matter what values are in the Static DNS 1, 2 and 3 the router continues to pull a DNS from my ISp. My POS old D-link 615 was able to utilize a custom DNS server with no issues so surely ther emyst be a way to do the same on the E4200.

I am wondering what is the optimal way to set-up my E4200v2 and PLWK400 at home? I have several devices (laptops, tablets, phones) that connect on .11g and .11n.
My current set-up:
E4200v2: 5ghz - Wireless-N only (SSID home-n), 2.4ghz - Wireless-B/G only (SSID home-g)
PLWK400: SSID home-ext (separate part of the home)
I am using WPA2 Personal security if that makes a different. One question would it be "better" to have the same SSID for all 3 wireless settings (5ghz, 2.4ghz, and PLWK400)? Would the various devices know which frequency to switch to for best speed and range?

I tried to upgrade my router firmware to the latest 2.1.39.145204 (downloaded from cisco website) but seems like the upgrade didn't go well. I am unable to open the admin webpage. I can get to the login page on 192.168.1.1, after i enter the admin password the next page doesn't load. It keeps showing 'Waiting' at the center of the page forever.. I have tried to do the 30/30/30 reset to no avail, i tried to do tftp downgrade to older firmware version but the tftp boot doesn't even start. Is there any other way i can either fix the current firmware upgrade or downgrade it to the previous version?

I purchased an e4200v2 to replace my old WRT160n which I have been using for years with no issues. Last night the e4200 crashed on me when I went to reset the router I noticed the CISCO light was blinking very slowly and I had no network connection. I power cycled the router and still no connection so I hit factory reset button. Nothing happened. Did a 30/30/30 reset nothing happened. At this point I have a 34 day old plastic brick on my desk and I'm back to using my old WRT160N. how to unbrick this router?

No problem setting up the FTP server on the router. It's working perfectly from inside the LAN. But any attempt to access the built-in server from the WAN side is fruitless. I found that if I turn off the IP4 SPI on the router, I can suddenly connect to the built-in ftp server without issue from the Internet. If the SPI option is checked, its a no go.
Is this a bug? I can't imagine that it is intentionally set up such that you have to turn off the firewall in order to use the FTP function externally. At least it isn't mentioned anywhere I can find and it wouldn't seem logical.

New E4200v2 @ firmware 2.0.36. The FTP server will go offline about once every 24 hours. I can revive it by simply clicking on Save in Storage/Administration or FTP Server. I don't have to change anything, just click Save. How can I keep the FTP running?

I have a small issue with Remote Management on my E4200v2.I have enabled it , select https and set Allowed Remote IP Address to any on the default port ( 8080 ).After all of this, I cannot connect to my router from my office or any other place. I'm using DDNS and all its ok ( updated at time ). I've tried also connecting to my direct ip address ( dynamic ) but with no result.P.S. no incoming log from port 443 using https.
