Linksys Wireless Router :: E4200 Not Getting IP Address?
Dec 21, 2011
I have a 6 month old Cisco e-4200 router that is updated to the latest firmware, connected to a Motorola surfboard modem on Sudden-link in Midland, TX.
I previously used this exact same setup on Cox Cable in Wichita, KS with no problems. Upon setting it up down here I cannot get the router to pickup an IP address. I have Power-cycled everything multiple times, did a complete reset and re-installation of the router software and still no luck. The Sudden-link techs have no idea what is wrong. They said that the modems signal is strong and everything should be working.
Actually I did get it to work once for a couple of days, however when redoing the surround sound system I had to unhook the cable line and it quit working and I haven't gotten it to work again since. I have tried unhooking everything. Turning it all off. Waiting for 5+minutes, and then reconnecting in order: First the modem, then an ethernet cable to the computer which will usually work. But as soon as I unplug the cable from the computer and plug it into the router it stops working.

I just bought the Cisco e4200 v2 router, I did all the installations as the Cisco connect software instructed me and everything went fine.After the installation I configured the router on the WAN settings as (Automatic Configuration - DHCP), like my old router (Linksys WRT54GL) and I saw that my router doesn't get the WAN address from cable modem from my ISP(it stays on 0.0.0.0), it doesn't renew the IP address.

My wife accidently reset the password on our E4200 wireless router and did not write it down. I have tried to reset the router as well as run the set up CD - no luck. How can I recover and get my wireless network back in operation?

After an indeterminate period my E4200 (firmware version 1.0.03) stops renewing the Internet IP address. This happens in both router mode and bridge mode.In router mode the E4200 is set for DHCP and connected to the cable modem, in bridge mode it is connected to a Dell switch with DHCP being provided by my Win2008R2 server.It appears that the device stops recognizing the existence of the Internet port - no lights come on when a cable is plugged in - whether connected to the cable modem or my Dell switch. Plugging the same cable into one of the 4 lan ports and that port lights up immediately (i.e. it is not a patch cable problem).If the E4200 is left switched off for some time (possibly days) it will work properly again for a while.

Frameware version: 1.0.03.
Environment: Internet (external IP say 24.x.x.x) ISP provided modem+router (192. 168. 1.x/ 24 IPTV network) E4200 (192.168.0.x/24 my home network).
The DDNS option page did report update succefully and shown the external IP address correctly on the page, however when I login to dynDNS it shows 192.168.1.x, which is the E4200 IP dhcp from the ISP's router.I know that it's double NAT, but the 192.168.1x/24 subnet is the IPTV subnet, and my old Dlink router did support and update the dynDNS entry properly.

I replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?

I've got threeLinux Boxes (running Centos 6). They were all connected to my cheap WRT54GL-- DHCP worked every time.Absolutely no problems. Both the LInux boxes and the WRT54GL had MTU set to manual, 1492.I replaced the WRTt54GL with the expensive E4200. I set the new router's MTU to manual, 1492. NONE of my Linux boxes ever receive a DHCP address. I look at the logs, and they do DHCPDISCOVER, get DHCPNACK, try several different intervals, and then fail the interface and quit.ALL I did was unhook cables from the WRT54GL and plug into the E4200. Yes, the WRT54GL was powered off. NOTHING was changed in the Linux configs. Yes, DHCP is enabled, address-range assigned, etc. BTW-- one box is dual boot with Win7-- in Win7 (using the same card, obviously), DHCP works just fine. But, Linux doesn't work.
I can give the boxes static IP's, and all is well. Just can't get DHCP to work. I evfen tried putting in DHCP reservations (via MAC assignments) for the E4200-- still doesn't work. The new E4200 is on the 02 firmware (which I believe is cuurent). If I can't iron this simple task out, in a couple of days I'm taking the E4200 back, and getting a refund. I'll stay with my old WRT54GL... it works. Hate to give up on some of the new E4200 features, though.

I've tried to cascade two Linksys routers, but It hasn't worked for me. The first one (which has cable-modem connection) is the brand new E4200, and the second one is the old WRT54GCv3.[code] However, the WRT54GCv3 doesn't get the IP address from the E4200's DHCP. I've also tried to connect them directly (without the PLC), even specifing an static IP on the second router, but I got the same results.I've to state I don't want to change the first router IP/gateway parameters because I have a web and game home server working with an static IP and I don't want to put it offline temporarily because of readjusting network parameters.

I have E4200 with fixed ip 192.168.1.2, DHCP off connected through LAN ports to FIOS ActionTec as 192.168.1.1. When connecting through wireless network off the E4200, I can obtain and connect fine under Guest network and WEP security, but for any other security setting, WPA, WPA2, Mixed mode, etc. I get the message "Aquiring network address" forever, and I never get a connection.

I have changed from a DSL internet service to a Comcast cable system. I have setup my E4200v1 router as an Access Point, to extend coverage in my building. It works fine, but I can no longer log on to the unit using its' IP address 192.168.1.1. The browser returns the message "Internet Explorer cannot display the webpage." If I want to tweak the settings the only thing I can think to do is to push the reset plug, back to factory settings and go through the whole process. Is there a way to discover the new IP address of the reconfigured router? I left the default address as it was when I made the changes to AP status.

I switched from Time Capsule with AirPort to E2000 and have a problem with configuration.I use the same IPs as in AirPort and E2000 gives me an error:"The WAN IP address cannot be the same subnet as the Guest Network IP address" and I can't save configuration.But in my opinion they are different.I use "Static IP" option and I have IPs from my ISP: [code] So WAN IP is different subnet as LAN and I don't know what to do now. It worked with these settings in AirPort and here I can't proceed.

I have a recurring issue with my e4200v1. My wired and wireless connections work fine, but I can't get to the administration website. I have https only set up, and after I get thru the 'certificate error' screen, I get an error that says web page is unavailable. Firfefox tells me that the connection was lost - error 101.I have tried wired and wireless, multiple computers, multiple browsers. I even turned the firewall off on one computer (or I think I did anyway).The only way I know how to fix it is by completely resetting then setting up the router all over again.

Upgraded from WRT610N to E4200. Since upgrading to latest firmware the wan just disappears both 5 and 2.5 Ghz bands. Happened with older firmware but not as often. Using it in briged mode. When this happens I can't even get to the management page with a lan connected pc. Have to do a hard reboot to get it to respond again. This is unacceptable for a router at this price point.

I am connecting the E4200 to a Sonicwall TZ100. I want the TZ100 to assign IP addresses to devices that connect to the LAN via the E4200.
How do I have the E4200 act as a WAP only or not assign IP addresses and push that responsibility to the TZ100?
I'd still want the E4200 to have a SID key for LAN access security.

I bought Linksys E4200, at a time that is the TOP of the line Cisco routers for Home use.I noticed a serious usage issue with it, I could not identify which are the wifi devices connected to choose for access restriction or parental controls, as the dialog box state only as "Network device", and software control by Linksys does not have any provision to use MAC ID or any other option "except " looking at the dialog box as "Network device".

I just received by replacement e4200 v1. I updated the firmware to 1.0.03 build 14 and am up and running just fine. The specs say e4200 should be 300+450Mbps. I am using a software "inSSider 2.0" to view my wireless setup. I get 144(N) at 2.4GHz and 450(N) at 5.2GHz. Please note these are max bit rates and not connect speed or throughput rate. The "inSSider" software gives me the following:
2.4GHz - 1/2/5.5/6/7/9/11/12/14/18/22/124/28/29/36/43/44/48/54/58/65/72/86/116/130/144
5.2GHz - 6/9/12/15/18/24/30/36/45/48/54/60/90/120/135/150/180/240/270/300/360/405/450
I get this information by hovering on the max bit rate field on the row displaying my SSID. So is it correct to say that my e4200 is not designed to reach 300Mbps at 2.4GHz. There is an earlier discussion thread about connection maxing out 144. Please note I am not talking about connect speed or thru-put speed. Max design bit rates of dual band router labeled e4200.

Just got a e4200. However I also have a cisco av power line adapter which worked fine. However when connecting to the 4200 it doesn't recognize the Internet. Have rebooted, reset switched ports etc. But it still doesn't work. It sees the network but not the Internet. Have tried everything ikon but no luck. Cannot connect my directive to the Internet. If I can't get it to work will have to run a 50 foot cable.

Firmware 1.0.00 on my E4200 Hardware v1.0 provided a functioning 6to4 tunnel through Comcast's 6to4 facility. Windows and Linux clients on my local network discovered IPv6 addresses and were able to use them successfully.Unfortunately, after the upgrade to 1.0.03 this functionality was gone. I missed reading the ChangeLog, which said that the automatic tunneling feature was removed in 1.0.01. The now provided IPv6 functionality works much less well. First, automatic configuration (discovery of the 6to4 via IPv4 anycast) no longer works with Comcast's gateway. If I configure the tunnel manually, by specifying a 2002/16 prefix, I regain IPv6 connectivity, but only for Linux clients on my local network.
Windows 7 clients suffer from the problem that because the E4200 hands out ULA addresses, they end up preferring those ULA addresses when making global IPv6 connections in the IP 'source' field, which of course does not work. It's like putting your company mailbox code as the return address on a letter you send via US Mail. Other home routers, such as the AVM Fritz! (url,...) suffer from the same problem. However, they provide an option to turn off ULA at the router.Is it possible to turn off ULA for the E4200?

I have an E4200 and the Cisco VPN client on my home computer that I use to access a work network. The VPN client cannot connect unless I either (a) bypass the E4200 and connect directly to my cable modem or (b) disable the SPI Firewalls on the router. I have all the VPN passthroughs set to "enable" on the router, but still cannot connect. The VPN client is using IPSEC over TCP on port 10000.

I've been trying to get FTP Running up on my router for some time now.
I know my current WAN address and have setup a specified folder on my E4200 for the FTP partition. A username for myself has been created with login info and I have forwarded the port I have specified on my router's FTP configuration page.
I try to log into the server, but whenever I try to log into it, I keep getting a "incorrect login information" message back at me.
If I cancel out of that then I get an error message saying it can't find the specified folder and to check the address of the server.
I know the login information information is correct and I've tried changing the password to others of varying lengths.
I've also tried changing the port I'm running the FTP off of incase my ISP has blocked that port, nothing works.

I have a 6 year old wrt54g that is working fine but old. I want to upgrade and will go with the 3200 or 4200. I really don't need the extra features on the 4200 since everything I have is hardwired (directly to two laptops and to two switches in other parts of the house for tv and printer). I want wireless for times when we move a laptop but it wouldn't be all the time, and we won't (for now) use the media options. The difference in price between the 3200 and 4200 is less than $25 so costs is NOT a factor in deciding.So should I just purchase the 4200 since price is not a factor or go with 3200; I want the most stable of the two and will never need the extra wireless features in the 4200.

I bought a Linksy E4200 yesterday and set it up fine, but I only seem to be able to get 130 Mbps on my Wi-Fi. I looked through these threads and tried disabling the 2.4Ghz band and it still remains at 130Mbps. There was no change, also read I can try set up a secondary SSID. I really don't know much about routers or configuring them

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?

I have been set out to pasture by the Linksys support staff as I have passed my 90 free tech asstistance period. I had a power outage and now I have a solid Cisco light on the top of the router but I can not get any port light activity on the router. I don't see how I can reconfigure it if the system can not even access it?

I will be staying at a rental property that has ethernet cable & modem. If I bring my E4200 v2 router from home & connect it to their modem, will my Toshiba 16GB Thrive be able to access the internet via WiFi? When I initially set up the router, I ran the router CD on my laptop, and the Thrive automatically accessed the internet. Will the Thrive automatically do the same when I connect the router at the new location. There is no computer there to run the router software. Will the the network be secured as it is at home? Same network name & password?
