Linksys Wireless Router :: E2500 Fails To Set DHCP Lease Time From Upstream

Jun 11, 2012

we finally got my Cisco refurbished E2500 configured and working downstream from a UVerse 3801HGV box. We had to change the default IP address of the 3801 because it conflicted with the E2500's default. The E2500 is set up to get its Internet IP address using DHCP from the 3801.  This is working fine for normal web browsing, etc.  However, anything that requires extended connections (downloads, streaming, etc) freezes after a couple of minutes, forcing me to refresh the action to get it started again.  Extremely annoying to say the least.

I'm pretty sure that I've tracked it down to the E2500's configuration of the 3801's DHCP allocation.  For some reason, the E2500 wants to set the DHCP Lease Time for the 3801's assigned IP address to 10 minutes regardless of the upstream settings from the 3801.  The 3801's default is 24 Hours which I've changed to 168Hours (7 days), but the E2500 stays stuck at 10 Minutes. Specifically, I'm referring to the setting displayed on the E2500 under Status>Router>Internet Connection IPV4>DHCP Lease Time.

Linksys Wireless Router :: WRT310N V1 DHCP Client Fails To Renew Lease

Apr 28, 2013

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.

Cisco Routers :: RV042 Fails To Obtain WAN IP Address Infinite Lease Time

Aug 24, 2011

I just got a new RV042. V3 Hw.For setup and testing before putting it in action, I've attached the WAN1 side to my internal network.But it fails to get an IP address, and the log shows: "Infinite lease time, exiting".My current router on the LAN is giving out DHCP addresses with 3 hour lease time, and I've checked with the PC's on the LAN that this is correct.The routers DHCP status shows that the lease time for the RV042 is 3 hours ahead.So why does the RV042 complain about long lease time ?Is there a way to avoid this error from occurring?
 
I have tried to change from 'Gateway' to 'Router', but this does not change anything.Also tried a factory reset, with no luck.Fw is upgraded to the latest 4.0.4.02

Linksys Wireless Router :: E4200 - Static IP Lease From DHCP Server?

Jul 8, 2011

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?

Linksys Wired Router :: BEFSR41 Can't Acquire DHCP Lease

Aug 9, 2012

a couple days ago my BEFSR41 started making trouble, and so far I have not been able to get it working properly again. When I hook up my laptop directly to the cable modem everything works fine, and I get an IP address via DHCP. When I connect through the router, though, the router status shows 0.0.0.0 for all DNS, gateway, etc. addresses, and even pressing DHCP Release/Renew doesn't change that.Also, in the log I see these messages:
 
2012-08-08 20:30:41  warning  DHCP RENEW WARNING - Field invalid in response
2012-08-08 08:30:52  notice  TLV-11 - unrecognized OID
 
Since I can connect to the cable modem directly, it seems the cable modem is not at fault.My overall setup is:
 
- BEFCMU10 cable modem
- BEFSR41 (not sure which version, but I believe it's a 4.x)
- WAP54G
 
Could it be that my provider (Cox Communications) has changed some configuration in their DHCP server, and my laptop (MacBook Pro) can handle it, but the router cannot?

Linksys Wireless Router :: E2500 And DHCP Routing Connection

Apr 11, 2012

We are using a domain and Windows Server 2008 machine with DNS/DHCP setup and active to handle traffic on the network.  The old router we had was a cheap (~$20) TrendNet that was configured (not by me) without issue to not only allow the server to handle IP's but also allow us to get in to the server remotely via Remote Desktop.  My cut sheet says they had a "virtual server" setup.
 
Anyways, we now are running an E2500 and if I put in the external IP, Subnet, Gateway, and DNS for our internet provider and then disable DHCP on the router, we don't get internet access.  I'm missing what configuration I need to get the server to handle all the traffic I guess.  The server has DHCP enabled with the router IP address (192.168.1.1) set and the server address is (192.168.1.2).  Like I said before it was working fine with our old router and none of the settings on the server have been changed so must be something with the new router.
 
Do I need to setup something in the advanced routing to get this working?  Currently I have DHCP on automatic and DHCP server enabled just so we can get internet access.  DHCP services on the server are still on as well.  Can't get any access to the server from the outside via Remote Desktop like we could before.

Linksys Wireless Router :: E2500 Linux Debian 6 (Squeeze) DHCP Failure

Nov 17, 2012

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.

Cisco Wireless :: WAP4410N Does Not Renew DHCP Lease

Jun 23, 2010

I have several Cisco WAP4410N access points.  They are configured to automatically obtain an IP address through DHCP.  This works fine, but I've discovered when the DHCP lease expires, the access point doesn't renew it.  It continues to use the same IP address but does not renew the lease.  If I reboot the access point, it will renew the lease again.Is this a known issue with the WAP4410N?  Is there any way to work around this, other than setting a static IP address or rebooting regularly?

Cisco Wireless :: Clients Timeout On DHCP Lease With Aironet 1141

Aug 17, 2011

I'm setting up a Cisco Aironet 1141 (standalone mode, AP) to handle wireless traffic in the office. It gives out 2 mbssids, one of which authenticates domain users through a RADIUS server and places them in an appropriate VLAN (RADIUS options 64, 65, and 81). The other is a guest ssid that uses WPA-PSK and places users in the restricted guest VLAN. Physically, the AP is connected to a 3750 PoE Catalyst, to which RADIUS and DHCP servers are also connected. AP, SSIDs, RADIUS and EAP authentication all work. The configuration given below is a working configuration. People do get authenticated and do get placed in the appropriate vlan. The problem is that, once authenticated, the "Obtaining IP Address" phase on the client hangs and most clients timeout without getting an IP address. Given that the DHCP server is on the same switch and a test simple ASUS Wi-Fi IP gives out the same scenario (except the multiple VLAN) at the speed of light, I don't think that it's a problem with the network connections between clients and the DHCP server. After reading some topics here, I realized that probably other communication will be extremely slow, as well, but haven't tested that for sure. Clients are all non-Cisco - smartphones, notebooks, etc. Most of them are 802.11G, not N.

Pinging Router Fails 5% Of The Time?

Sep 20, 2011

Lately I've noticed that my internet connection has been less than stellar. I will be playing an online game or surfing the web, and every so often I'll freeze up or things just won't run smoothly. My network consists of the following...All of my computers and devices connect to a Cisco 16 port gigabit switchThe switch then connects to a Peplink 20 Dual WAN routerThe router connects to a cable modem as well as a DSL modemThe other day I was trying to diagnose the problem, as well as update the firmware of the router. While I was on the main "status" page, I noticed an error saying that I couldn't connect to the router. It quickly cleared and everything was working fine. This of course made me think that my issues have to do with my connection to the router, and not with the internet service itself. I then tried ping -t to two other computers on the network, as well as the router. After 5 minutes of pinging, the connections to the two computers had zero fails, while the router connection failed about 5% of the time. I ran the same check from the other computers on the network, with similar results.So, I know that the issue lies with the router (I think), but that's where my brainstorm ends.

Linksys Wireless Router :: EA6500 Won't Obtain Lease

Dec 20, 2012

Small company, under 10 computers, wired and wireless printers, straightforward network. Do not need (nor particularly want) Smart Wi-Fi, Cloud Connect, or or anything other than a simple manually-setup router. Have a new EA6500 I plan to use replacing an E1000 that is playing up (needs to be reset every morning) connecting to Verizon east (former GTE) aDSL. Connected the EA6500 to a laptop via ethernet, changed router password to same as E100, set up the two port forwards I'll need (IPs on the internal network are static in the 192.168.1.0/24 block), changed DHCP server to start at 101 (don't ask), leave Internet Connetion Type setting at "Automatic Configuration - DHCP" (same as E1000), shut down both routers and modem (Westell WireSpeed 890-210015-04). Connect EA6500 to modem, power up modem, power up router, and...Nothing. Does not receive external IP via DHCP.If I switch back to the E1000, it immediately picks up the IP lease.

IP Address Lease Denied By DHCP Server?

May 5, 2013

my Laptop is about nine years old, HP Pavillion Pentium 4. I run Windows XP Home Edition Version 2002 SP3. I use a broadband card from Verizon that I just put in my USB (no router, etc) I'm getting a System Error Source DHCP Event ID 1002. When this happens, my computer, I believe, is going into sleep mode and I have to reboot the system. When I turn it back on and go back on the internet, all my websites that I was in are still there. The error says: The IP address lease 10.170.223.48 for the Network Card with Network address 2c3068c16ED1 has been denied by the DHCP Server 10.173.229.86 (The DHCP Server sent a DHCPNACK message)The DHCP Server Service did not extend the lease on your computer's IP address, so your computer temporarily lost its connection with the Network. I tried the ipconfig /release and ipconfig /renew. I tried going in services.msc and going under DHCP and keeping it automatic but stopping it. I called Verizon and I believe he refreshed my Network settings (I think I knew more about the topic than he did) He said it was my computer, whatever. I just tried the static IP but it didn't seem to take. I restarted and it jumped back to automatic. My last guess is it's something to do with the time frame of when it automatically obtains the address and when it expires. When I do the ipconfig /all it shows only a two hour time frame before it expires. Today I noticed that my computer shut down/sleepmode at the exact time the ipaddress was obtained. So, is there a way to increase this time between obtaining and expiring?

Cisco WAN :: ASA 5505 - DSL PPPoE / DHCP Lease Drops

Jan 25, 2011

I've been having this issue for about 3 months now, off and on, never seemed to be predictable but started happening more and more, which prompted me to look into it.
 
Currently, the DSL Modem is configured in bridge mode with the ASA handling PPPoE. The WAN address is being assigned via DHCP. The ASA is running 8.2(1). The WAN interface will drop it's DHCP lease and will not renew it without power cycling the DSL modem. I did a little bit of googling and found mention of setting "dhcp-client client-id interface outside", specifically this was an issue pre 7.2(22), but doesn't seem to affect my situation. Originally, I had the MTU on the outside interface configured as 1500, changing it to 1492 has not resolved my issue either.
 
I've enabled PPPoE and DHCPC debugging and posted the results below when the event occurs, I'm thinking this is moreso a PPPoE issue than it is a DHCP/DHCP Lease issue as I am not seeing any debug messages from DHCPC.

Cisco Routers :: SA520 DHCP Lease Clients Removal

Is there a way on the security appliance SA520 to remove someone from the DHCP lease client manually rather than setting the DHCP lease time to expire in less time like 4 hours or 2 hours. I was able to do this on other routers by highlighting the connected device and click remove. If not any recommendations on how to handle the device that are attached via DHCP and the person is no longer here, but the lease time is not up. I have set DHCP lease time to 4 hours.

Im facing with some DHCP lease issue and its like this,Our Cisco 2951 edge router is configured with local dhcp pool for a set of remote users when they connect through Cisco VPN which was working fine until we planned to change it to a Windows box that is configured for DHCP.The basic idea now is to relay the DHCP requests that are coming from the remote clients through Cisco VPN to the DHCP Windows server. So we added the scope on the server and changed the client config on the router as follows (highlighted is the dhcp relay config). [code]

Cisco Routers :: RVS4000 Is Not Renewing DHCP Lease In Auto Mode

Jan 25, 2012

my RVS4000 is not renewing DHCP lease in Auto mode. Connection lost after 24 hours.
 
WAN Internet interface is physically connected to cable modem - Motorola SBV6120E. Setup as DHCP server. Cisco RVS4000 is obtaining DHCP public IP without any issue, the problem is that the connection drop every 24 hours and I need to release/renew DHCP each day to be able to communicate after 24 hours. After I loose connection I need to release DHCP, the WAN interface goes down and I need to renew DHCP then. I receive the same IP address and connection is againg UP and working.
 
tried to load new firmware  and also setup the router with default configuration, but without any change. as there is no auto-reboot function, it is really annoying to log into managment interface each day. I also loose remote access after 24 hours, so I am not able to access the rotuer from outside. My local provider do not support static public IP on WAN, therefore I have to use DHCP.

Cisco Switching/Routing :: DNS Query Fails Behind DHCP / NAT - Router ISR 861

Nov 18, 2012

in my simple network setup, I cannot resolve DNS queries from inside my NATted network. On the router I can ping both IP-addresses and names. Ping from the  local machine works for IP-Adresses but not for names. When doing nslookup, addresses are not found and a SERVFAIL  message is returned. I use a Cisco ISR 861 Router to connect our local LAN to the Internet (The WAN of the 861 is connected to another DHCP/NAT-Router, which in turn connects to the ISP-Modem). Addresses in the local LAN are DHCP-distributed, the DNS-Servers from my ISP are configured on the Router and the DNS-Information is distributed correctly to my local LAN machines (as I can verify by doing nslookup on Linux).
