Linksys E4200 Wireless Router / Unable To Ping Machine On The Internet Side
May 7, 2012
I am using Linksys E4200 wireless router. I connected two machines, this way.
|LAP1|--------(LAN ethernet connection)----------|LinksysE4200|-------(Internet wired connection)--------|LAP2|
On the Linksys E4200, the Internet wired connection side, I gave static IP address which is in the same network range as that of LAP2.When tried to ping from LAP1 to LAP2, ping doesnot happen. Any settings by which I can ping from LAP1 to LAP2.

I've got a new E4200 router, Everything works just fine, but I'm unable to ping any WiFi hosts from my LAN, I can ping LAN from any WiFi Host.If I disable NAT on the E4200 I'm able to ping WiFi hosts but then all WiFi Hosts are unable to talk to the LAN.
LAN - 192.9.209.0
WiFi - 172.16.1.0
Same config runs perfect on my WRTG54GL.

It's been a pretty darn good router for about 8 months now, then today one of the wireless connected PC's started to go intermittent internet, and then dropped the connection.
At first I thought it was the PC, but after checking other connected items (wii, PS3, another pc, 2 ipods, and 2 printers) I discovered all the wireless connections were dropped, and no one could see the SSID. An hour unplugged fixes nothing. 2 wired ports are working fine though.
When it's uplugged and then plugged in, all the little lights come on, then go out, and then, only the 2 wired port lights come on, nothing else.

I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.

I have an E4200 functioning with a new Comcast/XFinity cable modem on the public IP (Internet) port. That modem provides a DHCP address to the router (currently 50.129.x.x./255.255.254.0) The problem is that this new setup is leaking COMCAST DHCP responses through the E4200 to my WiFi clients. Most of the clients (newer iPODs, laptops) are smart enough to behave correctly and use Wifi Protected Setup. This problem means that one older iPOD seems to be receiving the Comcast DHCP (as 192.168.33.0/24 range) instead of E4200 Wifi DHCP range (as 192.168.1.0/24 range). I imagine the most direct solution is to pull the public connection briefly and allow the iPOD to fetch a valid WiFi DHCP from the remaining DHCP server on board the E4200. HOWEVER, I'd like to configure the router to suppress all DHCP packets from the Comcast network - or otherwise make sure the WiFi clients only receive DHCP from the router and not the Comcast modem.

My E1500 enters a state where the LAN-side (broadcast, etc.) works, but the WAN-side (internet connection) just goes away. If I go unplug and replug the E1500 the internet connectivity comes back.When this happens, the wireless indicator on my desktop (Dell with Intel wifi) says I have an internet connection, but I clearly don't.

I've recently picked up a E4200 to build a dual band network which is targeting to link up (TV, media server, ps3, laptops) then (maintaining phones etc which only has b/g). While currently only laptops.Before doing any of these I have another cisco modem router DPC3825 which worked fine with giving wireless access.I first attemped to leave the modem router has is and connected the E4200 (ethernet 1 to internet), and changed ip to x.x.0.1 and x.x.0.2 while disabling wireless on the dpc3825 and the DCHP on the e4200 and have default gateway to x.x.0.1. My laptops can connect to wireless on E4200 but it couldn't get internet access.
Then I tried turning the modem to bridge mode & resetted E4200 (factory setting x.x.1.1, auto DHCP), and then connected my devices to both wireless bands. At this point I see router status obtained ip from ISP and Internet reached full speed per ISP's mark but the connection only held up for about 1 minutes. I noticed all the devices still maintained connection to router wirelessly but the router loses internet connection (lost the ip and couldn't get it back).

I have the e4200 and I am having trouble getting DHCP reservation to work properly with my Windows 7 machines. Perhaps there is a step that I am missing. Basically I go to the DHCP reservation setup page, select my machine and add it to the reservation table. Then I save the changes. As soon as I do this my computer goes offline. If I reboot my machine, it is still offline. I've tried the same procedure to reserve the IP address for my phone and it works fine so I wonder if the problem is with Win7.

This is what I have as a setup:BT Home Hub wifi routerPC with Windows 7 Home premium connected via ethernetMacbook Pro with OSX10.6 connected via wifiIt feels like i've tried everything to get this working. As far as I can see the settings are all ok but I've noticed that I can't ping the PC from the mac although I can ping with success the other way around tried traceroute from the macbook and it gives me this so it is able to see it somehow...Code:traceroute to 192.168.1.66 (192.168.1.66), 64 hops max, 52 byte packets 1 alistair-pc.home (192.168.1.66) 1.724 ms * 1.151 msNot sure where to go from here. I think discovering that ping is failing is a good start to diagnose.

I'm using Linksys E4200 router. I can't seem to ping the static WAN IP (from internally or externally). All other connectivity seems to be fine. I can ping the routers internal IP, as well as the cable modem and other external IPs. But all port forwarding through the E4200 is failing.Should the default security/firewall setting allow port forwarding? Or do some settings need to change?

E3200 works great until I enable QoS. The device uses QoS and works find until reboot. If QoS is enabled and the device is rebooted, its stops routing from LAN side to Internet side. Administration-->Diagnostics allow me to ping/trace route to Internet sites and local LAN clients but cannot reach Internet from local LAN.
Windows networking icon indicates "No Internet access". I can ping other devices on local LAN.
Disabling QoS restores routing and you can re-enable QoS after that and all is well. Unfortunately, if there is a power failure when I', not there to disable/re-enable QoS afterward, other household members can't use the Internet till I get home.
Wondering if any other QoS users have observed the same problem.

I purchased this router a few days after its release, and I was very impressed with its functions. I came from a DD-WRT flashed router with all the bells and whistles, and the E4200 lacked some features but I felt it was a fare trade off for the GHz & dual band.All was well with all my settings (quite a few to name QOS,forwarded, etc)I also updated the firmware when it came available and re entered same settings.
Approx 3 months after use I had 0 WAN connection via eth0 or WIFI, when I logged into router I was pulling a Public IP from my ISP. I could ping from inside the router but no connection on any hosts, very strange. Powercycling Modem/Router yielded same results.. I then backed up my vast amount of settings, and did a 30/30/30 reset.. With no configs I had no issue browsing on any host on my network. So I restored from backup and the issue was back again..So I did another 30/30/30 reset. Then went and reentered the exact same settings as before and the issue was gone.

just replaced a WRT54G with E4200. Most functions work well. 4 wireless computers (1 Macbook, 3 Win 7), 1 wireless android, 1 wired Win7 computer, 1 ethernet connected hard drive, 1 ethernet connected printer. All computers can ping router, access hard drive, access internet, ping android and ping Macbook.However, router, nor any computer, can't ping Win7 computers. Apparently IP based connections between WinX computers is blocked. My real applications are to Remote Desktop Connect from 1 Win7 computer to another, or to run a DLNA music server on 1 Win7 computer, accessed by another. (the LAN connected computer is the server, accessed by a wLAN client. All worked fine on WRT54G router, but can't connect thru E4200. When these apps failed, I tried PING, and that failed as well.All computer's IP addresses are properly served from E4200 via DHCP, and are visible thru the router's DHCP Reservation panel.

I recently acquired an E4200 Linksys router.Is it possible to connect to it using telnet (from LAN)? For example I would like to start a ping command directly from the router.I tried to telnet using command line shell from Windows and it failed to connect on port 23.

I have recently purchased a E4200 i have flashed it with the latest Firmware 1.0.03 and Hard Reset the Router so the Media issue was resolved i was having. After upgrading the firmware to the latest version my Nortel VPN IPSEC Client no longer will work. The tunnel is connected and it passes traffic for about 15 seconds then nothing. The connection remains connected but no traffic passes cant ping across tunnel. I have checked all the settings and VPN - IPSEC - Passthru is enabled. I have put the client in DMZ mode and tried that same thing.

i have my Cisco E4200 set up with a 6rd tunnel. the tunnel seems to work fine for the most part. i can ping ipv6.google.com and get a response.however, i cannot ping the addresses of the IPv6 Tunnel ends from within my network. If i run a ping from outside the network, i can ping the IPv6 address of the server end, however, i cannot ping the E4200's end of the tunnel. is there a specific option that needs to be set? i have allowed ping so that my IPv4 address is pingable, am i missing something for IPv6?

I noticed some serious random ping spikes in online games and found that the connection between my Laptop and the E4200 is very very unstable. Sometimes it works perfectly fine but at other times my ping will spike each 5 seconds to three or even four digits and back to normal. I never get disconnected but playing is obviously not possible.
I ran several pingtests through pingtest.net and got everything from 15ms ping 3ms jitter to like 400 ping 300 jitter.
Eventually, I pinged the router (192.168.1.1) and got delays between 2ms and 300ms for both the 2.4 ghz and the 5ghz network. The 2.4ghz channels are fairly crowded but the signal is perfectly fine and stable. The 5ghz band is totally free therefore interference shouldn't be a problem i guess.

I have a RV220W (running fw version 1.0.2.4) that i am trying to configure for a client. They are set up on Comcast with 13 available IP's. I should note that this netowrk is now currently running without issue using a Cisco Pix 506e. Unfortunately, the Pix is almost impossible to configure using the GUI now as I have to load a 4-year old version of Java now just to get the PDM to load. But I digress.I've set up the RV using the identical settings as the Pix on bth the LAN and WAN side. When I do, computers on the LAN side can all reach the Internet ok. However, once I enable one-to-one NAT for an internal server, that machine can't send or receive ANY traffic to the WAN side. I've even tried setting access rules enabling ANY traffic in both directions, and that has no effect. Either I'm missing something, or this is just one more bug in this product.
Even though it was a bit of a step down going from the Pix to the RV220W, it was done for the ease of setting up VPN's as I was ready to purchase a second one for a new satellite office opening in a few weeks. It looks like we will be switching vendors on the router side as my faith in Cisco is waning at this point.

Switching out a 5510 as our primary firewall with a 5520. I've essentially copied the working config from the 5510, and put it on to the 5520, making small changes where necessary. Plug everything. I cannot get out to the internet.
Facts:
-All interfaces have no shut on them
-No machine can ping out to the internet gateway
-All machines can ping out to the inside interface of the firewall
-It's not a problem with the internet because I can take a laptop, enter in our outside interface information, plug it into the internet gateway, and I can get out to the internet just fine.

Router: E4200
Router Firmware: 1.0.03 (Latest FW)
Why I cannot go to the 5Ghz band to utilize the superior speeds to transfer files over wireless connection between my computers? I am sure that I am still on the default 2.4 Ghz because
1) The file transfer speeds are pathetic
2) In Wireless Security, if I set the Wireless Mode to disabled for the 2.4Ghz band, Windows shows me "Unsecured Network" even with 2.4Ghz disabled.

I just bought an E4200 and it was working perfectly, very easy to install, all that it promises. Then I had an energy peak. For some reason, don't ask me why, I did RESET the router not thru the web nor thru Cisco Connect, but pushing the reset button at the back. I can't access the router anymore ! It keeps asking for a password that is never accepted. I have uninstalled cisco connect and tried again. Nothing. The router is not found. Keeps asking for a password. I tried everything: blan+admin, admin+admin, the password I used to have (provided at the cisco connect uninstall).It seems that the RESET never worked. The router is working thru cables, meaning when I can connect to the internet wired. But the router is never found wireless.How could I update the firmware if the router is not recognized (or if I don't have a username+password) ?

Been more than 2 years since I purchsed this router from US and has been working flawlessly till now. Lately I have been facing issues with few websites not opening when my laptop is connected to the router using a lan cable. Sites like speedtest.net (I get the download speed but when it needs to upload it is stuck there forever), [URL] is another which just does not open.
I tried opening these sites using e4200 wifi and everything works perfectly. I even updated the firmware to the latest 1.0.05 build 7 Aug 23, 2012 but still the same issue.
My router set to Automatic configuration - DHCP...
Also when I directly connect the internet cable to my laptop lan, everything opens without any issues.

I recently bought the E4200 v2. When I first installed, I ran the firmware update and then performed a hard reset (push reset button for 20 secs). I then began to enter all the PPPoE information and network settings into the new router (verified these settings with the existing WRT54GL router I'm current using and they all matched). I then disconnected the old router, and powered up the E4200. I was able to access the new router (192.168.0.1), I could see all previously shared files/computers with the new router, but I could not access most websites - usually I got a timeout error, or they eventually loaded in 10x the usual speed. This was typical of both laptops - one wired, and one wireless. My wireless handheld device could connect to the wireless network, and ran a speeedtest.net test, and upload/download speeds were normal - but I could not access the internet from the device. When I switched back to the old router, everything worked perfectly again. I have tried some suggestions on changing MTU values, but that did not seem to make any difference.
As a work-around, I have ended up keeping the WRT54GL as the main router and using the E4200 in bridged mode for wireless only (not what I ideally would like)..

Upon attaching my external storage I was able to create a share, copy files and access it successfully from everywhere. Now when I attempt to add an additional share, the router lets me create it but when I try to move access groups over from the available groups, the >> buttons are greyed out. The one working share has the admin and Everyone groups with access. Any additional share I create has the admin group in it by default, but I can't add any more groups. I am logged into the router as admin and logged into the pc as a local admin. I am also unable to change the rights from my pc on a share (access denied). I AM, however, able to map a drive to a new share successfully, but when I copy files over, a few minutes later the filenames are there but they show up as 0 byte files.

I've been on DSL with British Telcom Infnity (FTTC) since March and had no problems with the service. My router, however, an Apple Time Capsule, was not so reliable and needed a reboot every few days,So I just purchased the E4200 V2The Setup completes OK and PPPoE logs into my ISP fine. But then I hit the problem.Most of the websites I use simply won't load . In Safari on my OS X Lion, Macbook, I get an error like this "Request Timeout. The server timed out while waiting for the browser's request. Reference #2.525fdd58.1336048435.0" In IE on my Windows XP laptop, the error is "Internet Explorer cannot display the webpage"But some websites still load fine. So [url]..., loads instantly. Most other sites I try, including [url]... - won't load at all. (Plusnet is my ISP)If I connect to my work VPN, I can browse as normal
