Linksys Wireless Router :: E4200 Won't Give DHCP Address To Linux Boxes?
Sep 25, 2011
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 have a WRV4400n in my company and almost every day I have to reboot so people can get out to the internet, It lets you see the local network also if I put a desktop on line it will not give a DHCP address, untill I reboot the router. then all is fine, It has the latest greates firmware.

How can i set my OpenWrt 10.03 router to not to use 192.168.1.0/24? instead, use a /32 mask, so every client, that gets an ip from the DHCP server just can't sniff the network traffic - it would be a great security feature to safely use e.g.: FTP!

I have my other XBOXs connected to a 24 port switch but the one connected to the ea6500 directly gives me this moderate NAT issue. I thought this new router would be an upgrade to my old dlink but so far I get a new problem every day.I have reserved dhcp addresses for all the boxes and set up port triggering for the ports listed in several guides. But what else do I need to do? Is it likely I got a bad router?

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 just got a new E4200 v2 wireless router. I'm intrigued by the USB port, especially for using it to connect a printer. I currently have a D-Link wireless print server that I'm using to create a network-attached printer, but if I could remove an extra device and just have the printer connected straight to the router

Since firmware 1.0.02, E4200 supports connect printers to USB port and print to it from Windows using CiscoConnect.Is there any way to print from Linux (using CUPS, LPD, etc)?

When I try to connect OpenVPN through an E4200 v2 router from my Linux Fedora 16 client, the connection hangs. The connection log show that OpenVPN has connected to the VPN server. Internet also freezes until I disconnect OpenVPN.
OpenVPN on Windows works fine through the E4200 router.If I connect the Linux client directly to my Inteno fiber router, OpenVPN works fine.Passthrough is enabled in the router, and I have configured QoS and port forwarding for port 1194. The router has firmware version 2.0.37.

I have a Cisco/Linksys E2500 router. I connected to it through one of the Ethernet ports with a Microsoft Windows XP Pro machine and installed and ran the setup software. Windows was able to connect to the router and to the internet through the Siemens Gigaset 4300 DSL modem to my internet provider, Windstream.I cannot get my Dell GX620 which is running Linux Debian 6 (Squeeze) to connect to the router through the Ethernet ports.It appears that I receive no reply to the DHCP requests made by Linux.
I have only one monitor, keyboard and mouse and no KVM switch to run both the machines at once. I do have Windows XP Pro running in a VirtualBox virtual machine on the Debian machine,I can configure Debian to a static IP if I knew all of the IP configuration that the E2500 would assign. I would also need to know what reconfiguration the router requires if I use a static IP.

I'm trying to setup a DVR camera system and two web page server boxes behind a Linksys WRT54GL. The problem I have is that all of the devices want to use port 80 to generate the web page. Individually, I can get the boxes to work, but when I try to put it all together everything seems to fall apart. I've got to the DVR set to External port 80, Internal Port 80 IP address 192.168.1.254. The web page server box I try to set to External port 8001, Internal port 80, IP address 192.168.1.200, when I try to save this setting I get the error message Internet IP address and LAN IP address are in the same subnet. If I change the web page server settings to External port 8001, Internal port 8001, IP address 192.168.1.200, it will save the settings, but it won't work that way because it won't actually generate a web page when I try to access that port.The error message doesn't seem to make since as all I'm changing is the port number, not the IP address or subnet mask.

I have an e4200 set up and working on fios as a pppoe router properly with a dozen devices connected to it via dhcp. The dhcp range i configured in the e4200 is 192.168.1 100 to start with, and a mask of 255.255.255.0.
All the dhcp devices connected to the router start with 192.168.1.1xx. My Dell Inspirion with Windows 7 has an ipv4 address of 192.168.15.2. I cannot figure out how it gets this address, even after I release and renew the address on the Dell.
Everything is working fine so I guess there is something I just do not understand.

When I'm in Setup -> Basic Setup -> click on DHCP Reservation, I don't see all entries I've created earlier but computers that connect still have the correct IP address on the network; I don't know if I can create additional entries if nothing appears
When I go to Status -> Local Network -> DHCP Client Table the list is blank but some computers are connected to the networkI'm using firmware 1.0.01 build 10 Feb 21, 2011, language = English, Firefox 4.0.1.Rebooting the router doesn't change anything, I can't see connected LAN equipment and DHCP Reservation is empty despite the fact I've created entries.Together with the "Access Restriction" which doesn't allow to block a computer from 10pm => 8am unless you create 2 rules + various issues with attached USB + 2.4Ghz signal that is far from optimal (never able to achieve more than 144-N-Mbps) and I ask myself if I will not contact the store where I purchased this unit and ask a refund (and buy something else from another brand...)

I have ten E4200 routers deployed in five library branches. In recent months, the E4200's in two branches have occasionally gone into a state where they are not always providing an IP address to both wired and wireless devices. Some devices will get an IP fine and others will not, The problem seems to move and the next day the same device will connect fine and others will not. A reset of the router usually clears the problem but it is becoming more frequent and bothersome. For some reason only two locations are effected.
Some notes:
- Firmware version is 1.0.02 build 13
- When I set devices up with static IP's they work fine, so the problem seems to be related to the DHCP service
- The WAN side of the network tests fine with no issues
- I've had these routers deployed for over a year and this problem just started in the past two months
- Routers and AP's are on different channels to prevent interference
- No nearby WiFi signals appear to be casuing any interference

The e4200 1.0.03 DHCP server appears to be quite buggy. After configuring a static IP / reservation for a client which already had a dynamic IP from the pool, the e4200 continued to offer this client its pool IP. However, the DHCP client listing in the e4200 showed the client having the static IP even though it was still being offered that pool address.This may sound like user error, but I can assure you, it is not. I have had a very frustrating experience with this product, and rather than fool with tech support again, I ran `tcpdump -e -s1600 -n -vvvv -i eth0 port bootpc or port bootps` to absolutely rule out a mistake on my part, bug in the DHCP client, etc. I found that the client was always offered that old IP, even thought the e4200 status display showed the "new" static one, after doing a DHCPDISCOVER without requesting a specific IP. This condition persists across e4200 reboots even after having the client release its lease!I finally was able to resolve this by forcing the client to request the static IP from the e4200.This is unquestionably a bug in the DHCP server, and additionally, the user interface does not show the real state of the underlying DHCP leases held by clients which have static addresses / reservations. Troubleshooting this condition is well beyond the abilities of the average user.

Why is it that the dhcp on my router is no longer able to give out ips or rather it assign them as for as it concerned as it will list say 199.170.0.102 but the device will have none or make up one for it's self and never get the ip that the routers dhcp gave it this happens on all devices. I know power cycling will fix it temporally but usually it will start doing it again in a few hours also I know that I can use a static ip this was my way around this problem but I have one device that won't use nothing but dhcp a printer. I had an old linksys router that did this and I figured it's old it's slow time for a new one after a few months it started, some computers are on the fringe of being able to get a signal but are still fair also even with static ips they sometime stop connecting and we have to disable the connection then reconnect to fix it the router is a dlink 615 dual band set to only G/B because 1 most devices only g 2 the one computer that has a wireless n is 70 ft away and works better with g.

Is there a way to get the E4200 to NOT provide itself as a dns server to the DHCP clients? I have the unit set up to provide two dns servers to the clients, but the 4200 always provides itself as a third and it uses my cable providers dns servers. I am using a dns based filtering service to prevent certain material from being accessed within my network as the first two resolvers. So long as both or one of the provided servers is working it doesn't fall back to the unfiltered third, but I would prefer to remove it entirely.

I just bought a Linksys E4200v2 router and updated the firmware to 2.0.26.124551. The DHCP server is turned on however, it won't issue any IP addresses. I have to set IP reservations for all of my devices in order for the router to give them an IP address. This includes my printer, xbox360 and 2 computers. I'm also having this problem with the wired and wireless lan.

I just purchased an E4200 router. I have four clients on my network and they are all set up for DHCP. I renewed their IPs and they all are connected. "Cisco Connect" reports that I have four clients connected. When I access the router and bring up the DHCP Client Table, there are no entries. There should be four entries. Aftern I enable the logging function, none of the logs have any data in them even after I wait for 45 minutes and use the internet and renew IPs. I am using Firmware Version: 1.0.03. I have the same results for both Chrome and Firefox. I want to be able to set Static IPs but I am hampered by the not having any clients in the DHCP client table.

I just bought an e4200. I was using a LinkSys WRT54GS running DD-WRT alternative firmware.
One feature that I really liked in DD-WRT was the ability to assign static IP leases from the DHCP server. I liked having all of my devices running with a predictable, known IP address on my network. I have a Home Theater PC, and various controller applications that run on iPhones, etc. - some pretty homebrewed. Configuring the firewalls, etc. was much easier with IP address based controls.
Is there a way to achieve the same within the e4200's stock firmware?

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.

I have 2 Media Bridges, a Trendnet TEW-640MB and TrendNet TEW-680MB. Both are set as a Static IP on the devices 192.168.1.150 and 192.168.1.151. In the DHCP table for my E4200 I don't see those. I have no problem accessing them typing in those IP addresses but wondering why they don't show up in the table.Actually looking at it more closely, the devices hooked up that are active seem to show up.So I see the following below. And where is list LAN but no name those seem to be devices connected to the media bridges.

On my new E4200v2, after I tried to move beyond the disappointment of Cisco removing Internet Access Policy entirely, I decided to give the stripped down Parental Controls a try.
Sadly, I didn't have any luck doing what I needed to do... block my Tivo's from accessing Youtube.
I enabled Parental Controls, Added the Target Devices (my Tivo's did show up), and added "Youtube.com" as blocked site #1. Saved. Entered the parental password when prompted. Even rebooted the router.
But Youtube wasn't blocked. So I added to the target list a non-Tivo device (a Macbook) for a reality check, and rebooted the router again... still no luck. Youtube still not blocked.
So then I started to wonder if their Parental Control depends somehow on the local DHCP server & Client list. Because my E4200 has DHCP Server = OFF (I have always used a Windows Server for DHCP).
I tried to call Linksys support to get this working, but after 45 mins, including escalation to senior engineer, they really were pretty useless (no real familiariarity with my problem) then they disconnected my call!

I am trying to determine the best way to setup my E4200 V2 so that it is “uplinked” correctly to a Comcast Dory Modem/router. Currently we have the E4200 V2 router plugged into the Comcast Dory Modem/Router using a CAT6 cable from one of the Ethernet ports on the Comcast device to the WAN port on the E4200. The E4200 is set to “Automatic Configuration - DHCP.”
We are trying to do two things. First better WIFI in the center of the house and for a TV located next to the Comcast device, and second, have all devices in this house see and access all other devices including the Samsung SmartTV, my son’s two systems upstairs, the 3 systems in the room with the E4200, and the one network printer. In the room with the E4200 we have 3 computers and one network printer. 3 of those 4 devices support WIFI so we don’t have to use all 4 Ethernet ports on the E4200.
I see others talking about running the CAT6 cable to an Ethernet port on the E4200 instead of the WAN port and setting it to “Bridge Mode.” Right now the system appears to be working fine although we are sometimes experiencing brief dropped connections with the devices hardwired into the E4200.
Should I be running the E4200 in “Bridge” mode or “Automatic DHCP” mode and which port on E4200 should the CAT6 from Comcast be plugged into?

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.

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.
