Linksys Wired Router :: WRT54G Maximum Value For DHCP Client Lease Time?
Jun 26, 2011
On the BEFSR41 v1 series and WRT54G series, what is the maximum value for the DHCP "Client Lease Time (in minutes)?" It seems that 2^16 -1 (65535) minutes is the max. This is about 45 days. has the max value changed with newer versions of these devices?
I'm trying to change the DHCP Client Lease Time from 1440 minutes to 480 minutes. When I try to apply the new settings, I'm getting a message that says "Invalid Characters" and it won't stick. I've tried this in three different up-to-date browsers (ie10, Chrome and Firefox). Also, I'm connecting locally through LAN and I have the latest EA6500 Firmware: 220.127.116.11204
i cant seem to change my dhcp lease time even though i change my Client Lease Time to 1 day. Firmware Version:v1.0.06 build 001 Apr 29 2011 11:08:40Boot Code Version:v0.03Firmware Verification:Current Time:Sun, 25 Sep 2011 10:15:32 PMInternet MAC Address:Host Name: Domain Name:
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.
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?
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.
Most devices pass a client name to DHCP when requesting an IP, but some like my smartphone, do not. When a device does not pass a client name garbage is entered as the name of the client name.The first is that when you use the Web Admin pages, and select Status/Local Network/DHCP Clients, the table will not display any clients because there is an error on the page. If you right click and View Source from the browser, you will see all the client entries are there and one of them will have garbage (unprintable characters) for the client name.The second and more serious issue is that the internal DHCP table once corrupt is unstable. I've had my BEFSR41 reboot because of the corruption and then I get IP conflicts on my LAN because the DHCP starts handing out in-use IPs.I'm on hardware version 4.3 and the latest firmware Ver.2.00.4 Build 8 (which is very difficult to install without bricking the router). BTW, when I use a WRT54GL router with the smartphone, it is properly handled by the DHCP and shows a blank client name, not garbage.
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 smc wireless cable modem gateway router lease is set to expire every 7 days does it matter if its like more often, is this good enough, i was told every day might be better as i get better connection.
I just bought a new Linksys E4200, and connected it about an hour ago. I have a 30Mbps internet connection when connected direct to the modem, but when connected wired to the router, max speeds are 8Mbps.
I keep trying to set access restrictions for my wrt54g router for time. There is no 12 for time so I'm selecting 11:55 pm to 6am but I keep getting an error message of, "end time must be bigger then begin time." I get this no matter if I select 9pm, 10pm, etc.
I've brought a SG300-10 switch and would like to connect it to an Apple Time Capsule (as the base station of my wireless network), Apple Airport Extreme (to extend my wireless network) and 3 x NAS. What is the best way to connect?
Internet > SG300 > Apple TC + NAS x 4 + Apple Airport Extreme (to extended my wireless network) + Mac Pro/iMac'sInternet > Apple TC > SG300 > NAS x 4 (connect to the SG300) + Apple Airport Extreme (to extended my wireless network) + Mac Pro/iMac'sI need the SG300 because the Apple TC doesn't have enough network ports to cennect all my other devices.
DSL modem works fine when connected directly to computer. No internet output from WRT54G wired or wireless, but wireless network is recognized by computer, just no internet. I did a reset and installed the latest firmware, then I ran thru the setup CD that came withe the router, and the internet test said no internet connection was available. Cables are fine, connector innards look clean.
Do the problem caused by the modems itself or it just sign of faulty Ethernet switch (using 20 port Allied Telesis ethernet switch). Sometimes I cannot connect to internet due to "unidentified network" buy i can resolve this problem by restarting my modem + switch.
I have the WRT54G router for years and use it to provide both a wireless network for our home computers and a wired network for by internet phone that connects me to my office phone system and for my work computer and printer. Last week, the wired network stopped working. I checked the wiring and plugged my wire into all four of the ports in the back of the router with no success. I followed the troubleshooting procedure that I found and changed the MTU setting. I tried to update the firmware but the screen seemed to lock up and I was unable to complete the task.
Dropped VPN connections.I experienced a similar issue a few years ago with my LinkSys WRT54G router with dropped connections to my corporate network using the Cisco VPN Client. To make a long story short the problem was the result of the following:
1. The default ""Client Lease Time" on LinkSys routers is 0 which means 1 day or 24 hours.
2. By DHCP Protocol definition, DHCP clients must renew the DHCP client IP address lease at the 1/2 life cycle of the lease (12 hours if using the router's default setting). This is deadly for VPN clients as the short period of time when the client IP address is no longer valid, the VPN client considers this a loss of network connection. The LinkSys E-series routers further aggravate the situation by randomly assigning new IP addresses to DHCP clients instead of reassigning the client's previous IP address and tends to favor higher host IP addresses in the defined range.
Suggestions to prevent lost VPN client connections:
1. Change the "Client Lease Time" on the router to 8640 minutes (6 days 00:00:00).
2. Prior to establishing a VPN client connection, use the Windows Command Prompt to issue the "ipconfig /renew" command to obtain a new IP address from the router that will be good for 3 days (72 hours).
3. Configure your E-series router to use the <DHCP Reservation> option to pre-assign IP addresses to your systems making sure they are outside the range of the dynamically assigned DHCP addresses. Using default settings,these would be in the range of 192.168.1.2 thru 192.168.1.99 as the router starts at 192.168.1.100 thru 192.168.1.149.
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
I have an RVS4000 located at my office. A user of mine also has one at their house. We have created an IPSec Tunnel between the 2 of them and have them successfully communicating between the 2 networks with no problem.
The problem I have is if I make a change on their end and the router needs to reboot to apply the changes, the WAN port never renews it's DHCP address. The end user must unplug the unit, plug it back in and then the system comes back up with the correct WAN DHCP address, and the tunnel is connected automatically.
I beleive they have the newest firmware (18.104.22.168) but I cannot confirm that right now as the unit is down. I bought the 2 of them at the same time - my unit at the office has the 22.214.171.124 firmware so I am assuming the users does as well.
We have a Network set up with a RV042 router. Router is hooked up to Cox Cable and ATT DSL. Currently have 20 computers hooked up to the router all using Static IP addresses. Setup has been in place for over 7 years. I want to set up a Wireless Access point on this network. The problem is, I can't seem to get DHCP to work right even WITHOUT the Wireless Access Point. I have taken one of the computers that works great with a static IP and changed it to be DHCP, I have enabled DHCP on the router and set the from and thru parameters for the IP assignment. The computer will connect and get an IP address and it allows me to see all the INTERNAL servers on the network but going to the Internet is REAL FLAKY. I usually have to refresh 5 or 6 times to get a web page and sometimes even that don't work. If I do get a page to come up there is about a 10% chance that it will bring up a subpage of that page without doing a refresh 5 or 6 times. Its like it won't hold the connection to the Internet. I did notice one thing different in the User Manual of the RV042 that is different than all the other Linksys routers I have worked with. It says that when you enable the DHCP on the router, you then make sure ALL computers hooked to it are set for DHCP. All other routers I have worked with do NOT use that word ALL. Am I missing some setting or is this a binding thing where you are either ALL static or ALL DHCP?
I have a BEFSR41v2 and have since upgraded to a wireless router. I now need a hub and have read that I can disable the DHCP in the BEFSR41 and use it as a hub. If I understand what I've read, I hook the cable running from my current wireless router into the uplink port on the BEFSR41 and then have the 4 ports available for expansion without using the WAN port - does this sound correct? Also - should I have the router (now configured as a hub) set to obtain the IP address automatically, set a static IP address or what? Finally - the firmware is the original firmware 1.42.7 (April 2, 2002) and I've read where people have problems after updating the firmware.
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.
- 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
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?
I have a Linksys WRT54G router; have a cable internet connection through the router; and two wired desktops, one running Vista (32-bit) and the other XP. I would like to replace the XP machine with a wired desktop running Windows 7 (64-bit).
I am attempting to access a VPN hosted on Windows 2003 Server using my Windows 7 SP1 / 64 bit laptop. I can establish the connection and even open Outlook and connect to the exchange server on the remote network. It seems that whenever I try to move files up or down or open Internet Explorer, the following sequence of events happens:
1) Connection between my local router (BEFRS41) and the internet is dropped. 2) The IP address on my local network adaptor changes to an unknown number (169.254.180.72) - is normally 192.168.1.104 3) The VPN connection drops and attempts to re-dial, but of course fails because my connection tot he internet has been broken.
Since I'm accessing rather than hosting the VPN, I'm not sure if I have to adjust any of the router settings.
