When I enable IPv6 on my E4200, the Windows 7 DHCP client crashes. It also seems to crash the audio service, the event logger and a few other windows services.
View 9 RepliesI 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
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.

If I "Disable" the DHCP Sever, the setup menu provides a method for me to force feed up to three Static DNS addresses, all with IPv4 addresses.
There are several locations that provide "free" DNS service, but how does one verify the security of such sites? Does Cisco keep track of the status of this kind of service or am I on my own? Cisco seems to endorse two DDNS services, but for home use, the extra charges seem otherwise unnecessary, and do not yet address the IPv6 question.
The first few that I have investigated that do provide IPv6 service also provide their addresses in IPv6 format. The E4200 menu does not seem to allow me to do that.
Am I going to be forced to live with crippled IPv6? I have already discovered a software product that has failed since changing routers, but works if I take my laptop to a particular WiFi location.
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?
View 7 Replies View RelatedI flashed the firmware and the ipv6 automatic is on disabled and I cannot set it to enabled.the 6rd tunnel option I can change but that has not effect- in fact from what I looked up it seems to be something used by some cable providers.hate to have to reset the router to factory defaults and then reset the network up - just to see if i can get the option to set IPV6 auto to enabled.

ipv6 dhcp client pb
I have configured this on a 877 router with no problems. I have tried 15.0(1)M3 and 15.1(3)T.
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.
I've assigned an ip address to my htpc using dhcp reservation. On my old router I could use the client name, for instance: ssh name@clientName Instead of: ssh name@ipAddress Currently I cannot do this with the stock cisco firmware (unless I'm mistaken). Is there something I have to do to get it working? Or do I have to resort to tomatoUSB/WRT.

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.
View 9 Replies View RelatedIs 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 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.
View 4 Replies View RelatedI 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?

View 3 Replies View RelatedI just got an EA3500 and I guess I don't understand what "Refresh" does when viewing the DHCP client table under the "Status", "Local Network" tab of the web interface, either that or it's not working. If I have active wired and wireless clients and I power off the EA3500, wait a few minutes, then power it back on, the table is blank. If I hit "Refresh" I would expect it to re-populate the table with the connected clients. For whatever reason, it doesn't. I have to physically disconnect and reconnect the E-net cable, or power cycle the wireless client to get them to reappear in the table. Is something wrong with the router or its s/w

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.

View 3 Replies View RelatedOn 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 a Linksys WRT310N v1 with firmware v1.0.10 build 002Jul 19, 2010 My router fails to renew it's DHCP lease from my cable provider, causing internet access to drop. I can still access my cable modem at 192.168.100.1, but I must do a "IP Address Release" then "IP Address Renew" to get back internet access. The router works fine otherwise.

I have a NAS drive plugged into it and my laptop is on the 2.4 spectrum. I went to transfer 8gigs of data from laptop to NAS drive and the entire wireless portion of the router locks up. All my wireless clients drop and I have to unplug the router and plug it back in. Even the 5ghz clients drop as well. I have not tried hardwire, but the main reason I got this was for its throughput.
View 1 Replies View RelatedI 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.
View 6 Replies View RelatedI 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.
