DHCP client Table

I have a WRT54GL router and in this table my computer was 192.168.1.100, now it is 192.168.1.102. Is there anyway to change it back to 100. would solve allot of my problems in the event viewer. Windows 7 home premium 64 bit.
Solved!
Go to Solution.

The easiest way for you to accomplish this is to set your PC for a static IP of 192.168.1.100, then set your router's starting DHCP address to 192.168.1.101.

Macs show up as "unknown" on my router's DHCP Client Table

Both of my Macs, an Intel Mac Mini running Snow Leopard and a G4 iMac running Tiger show up as "unknown" in my router's DHCP client table.
All of my Windows PCs all show up with their computer names.
Is there a way to get my Macs' computer names to show up in the DHCP client table? The router is a Linksys RTP300.

Open Network System Preferences, click on the service you are using to connect to the network (airport, ethernet, etc), click on Advanced and go to the TCP/IP tab. There is a field for DHCP client ID. This may pass a name to the router and it may use it. I don't know.
Another option is the WINS tab. You can set the Netbios name (other than the default) and workgroup (and any WINS servers, if you know their addresses).

Missing hostname in DHCP Client Table???

I give up. I've searched the internet for an answer to why my mac's hostname does not show up in my WRT54G's DHCP Client Table and come up empty. I see host names for my windows and linux boxes, but not my macbook pro. Anyone have a clue?
Thanks,
Steve

I have a BEFSR81 with the latest firmware (2.51.3) and I have also noticed missing hostnames in the DHCP Client Table. I have a couple of scenarios that this appears to happen.
The first case is if the router is power cycled, the DHCP Client Table will obviously be empty, but even waiting up to 24 hour later for a default renewal, the hostnames are not updated and most remain empty. The only way to get the hostnames to appear is to reboot the machines where the hostname field is empty.
The second case is that some of my network devices never have hostnames in the router's DHCP Client Table.
The last case is when the entire network (machines as well as the router) is restarted. The router is started first and there are no Clients in the DHCP Client table. Then the clients are started and the DHCP Client Table fills up. After 24 hours, the client table will slowly degrade to have several missing hostnames, but the machines are still there and they are at the same address.
Is this a known problem with this router?
I had a Vonage router (Linksys RT31P2) and never had these problems. On the RT31P2, the DHCP Client table always had all the hostnames.

DHCP Client Table not accurate (EA4500)

I have DHCP enabled, but I have assigned a static IP to most of my network devices.
When I click on the DHCP Client Table, most of the devices are NOT shown even though I know they are connected and working.
One device (a Brother printer) that I have assigned a static IP to actually shows up as having an IP from the DHCP range.
A Panasonic TV does not show up at all even though it is connected and woking. I have not been able to assign a static IP to it because it does not show up.

And another thing, you know your device is connected through the ip address that it is getting and if you can ping your router's ip through that device.

Why doesn't my E4200 wireless router show all attached devices when viewing the DHCP Client table?

I recently installed some wireless IP cameras and when attempting to re-install a camera I went into the DHCP Client table to verify which IP a camera was using to set it up, but I could not...and still cannot see any of my cameras in the table even though I can access three of them directly through the IE web browser. I initially power cycled both the E4200 router and Motorola cable modem, and then later just the wireless router...but I still do not see the devices connected. I currently have 2.0.37 firmware even though I was told by Cisco support that there was a later version available, just before being informed that I do not have support available and could purchase it. I attempted to locate a newer version, but the online upgrade portion of the Cisco Connect software searched the net and then states that I have the latest version available. I also opened a Firefox browser to see if maybe my browser was causing issues, but the same limited table appears without all entries available. I even opened the Cisco Connect software on another laptop with the same limited results.
Other than a factory reset, any suggestions to get me E4200 dual band wireless router to show all attached devices through the DHCP Client table as it previously did approximately two weeks ago? Thanks!

It is strongly recommended that you upgrade the firmware to a smart wifi, which may resolve lot of bugs. You can also download the firmware here:

WRT300N DHCP Client table won't populate in Vista

My web access to WRT300N won't populate the DHCP client table.
This is a completely clean install of my PC and my router. In fact, I wiped my entire PC and loaded a clean copy of Vista on the PC. Initially, all clients in the DHCP table were visible. However, after running Windows Update (after a new install, it updates about 47 things), the clients in the table are no longer visible.
The router otherwise works fine. But something is blocking the DHCP table from populating.
The firmware on the router is Firmware Version: v1.03.6. I'm using Vista. The problem occurs with both Firefox and Internet Explorer (most recent versions). My Java installation is the most recent version.
In Internet Explorer, there is a little error icon at the bottom of the screen. Double clicking on it and opening the "Details" reveals this:
I've searched the forums and Google and found nothing about this. Does anyone have any solutions?

It's not IE...or Firefox for that matter. They both worked and showed the router table earlier. The only difference was downloading the Microsoft updates and the Lenovo updates for my notebook. I think it was something in one of those updates. I may have to sit here and figure out how to system restore back to the time before they were installed and reinstall them one by one. What a pain. I was trying to prevent that.
Disabling antivirus protection was a good thought. I disabled Norton and all of its little subprograms, and it didn't make a difference.
And as far as connecting a different computer...got one I can borrow? It's a good idea, but I don't have any extras lying around, so I can't work through the error that way.
Hoping for any other suggestions before I wind the clock back on my computer's installation.

Linksys E2500 does not show any devices in DHCP client table

Equipment:
Old Westell DSL modem, still runs like a champ
Linksys E2500
home built desktop running Linux 12.10
We're having intermittent WiFi. This morning I finally sat down to do some troubleshooting. SOP for me is to reset both the modem and the router. Modem bounce went fine.
Before bouncing the router I did some nosing around and noticed there were no devices listed when I nosed throught the DHCP client table, not even the wired connection for my desktop. There should be 2 MacBooks, an Apple TV device and a Galaxy S4 showing up.
The other oddity - on a lark I switched the MacBooks over to the guest connection and there have been no problems with wifi since.
What gives...?
Any and all help will be greatly appreciated!

You make sure that the router's firmware is up to date. Reset it again since that's recommended after the upgrade and reconfigure the settings again. All devices in your network connected/ utilizing the router's DHCP server should be listed under the Clients Table.
For the intermittent wireless issue, try changing the wireless settings; ssid, wireless channel, and the security. For the channel, play around with channels 1, 6, 9, and 11.

WRT54G dhcp clients table missing linux boxes - only windows listed

I've searched the forum and similar messages and other routers mention that a firmware update will fix the problem where not all dhcp connections show up in the status/local networks/dhcp clients table.
I have WRT54G hardware version 6, firmware v 1.00.06.
I've looked at the firmware updates and no mention of this problem appears. I don't want to needlessly update my firmware.
Does anyone know if this problem has been fixed in the latest firmware?

More info:
It seems that the linux box (ubuntu 7.04) is using the bootp protocol, not full dhcp. From some reading of the rfc's it seems that dhcp is an enhancement to bootp, and it is valid for clients to request an ip address from a dhcp server (the protocols use the same ports etc.).
However, bootp does not deal with a lease and since the dhcp client tables list a lease time, I am guessing that this different way of getting an ip address is what is messing with the router.
On the one hand, it could be said that since it's not a full dhcp client, the router would be technically correct to not show it in the client list.
But, it does make for a bit of a messy situation as some clients can appear invisible to the network configuration manager. This could be a security issue.

Refreshing the DHCP client table

I 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, or is that not what "Refresh" is supposed to do?
Thanks in advance for any thoughts you might have.

The thread below would seem to indicate that this problem has been around awhile with different routers. The lease times will refresh, but devices won't appear if they're not already in the table.

When your computer needs an address, it will send a demand to the router using DHCP. The router's DHCP server then LEASES an IP address for a short amount of time. The computer has to RENEW the lease once in a while to make sure the router knows that the address is still in use. Routers like these save the DHCP information in temporary memory only. When you reboot the router, it no longer remembers who has what address until someone renews again.

? Retrieving DHCP Client Table ?

I apologize in advance if this has been addressed in the forums, I have searched and looked manually but to no avail as yet. Please advise to url if Thread exists. TYVMIA
My DHCP router:
BEFW11S4 v4, f/w v1.52.02
The DHCP-disabled router (as hub?):
BEFSR41 v2, f/w v1.45.11
My DHCP clients:
3 Windows XP Home - based PCs
1 XBox (original)
1 XBox 360 "Elite"
1 PS3
1 Brother 420-CN MFC via LAN
My issue:
I've managed to "lose" my DHCP Client Table via the router's web interface. I'm referring specifically to the Table which is accessed through the "Status --> Local Network" tab of the interface. Actually, the Table is still accessible but I can't use it to show me the information for the active IP clients. I think I lost this information when I mistakenly deleted the active IP clients from the table. (I misunderstood the function of the "Delete" execution of the Table.)
My question:
How do I re-quip the router's software so that I can access/read the information about the devices on my network.
My motivation:
Troubleshooting device connectivity. Specifically, 'Net access for the gaming consoles is interrupted, though all other devices can fully access the 'Net without interruption of services.
Again, thank you in advance very much for any insight, advice, suggestions, or guidance regarding my situation. I am glad to offer any other technical information as requested. Have a blessed day : )

not quite sure abt getting back the information on the DHCP client table ... may be you could resetting and reconfiguring the router and check whether this makes any difference..
regarding the interruption in the internet connection while playing games ... i have a question for you....does the internet connection drop on the computers while playing the gaming consoles ?? if it is dropping then its the bandwindth issue as online gaming need a lot of bandwidth ..

EA4500 DHCP Client Table erased

My EA4500 will periodically clear out the DHCP Client Table and I will lose internet access.This happens once almost every day, normally in the morning. If I can't access the internet I will check the DHCP client table under Status -> Local Network -> DHCP Client Table and it is always empty.
After I select Setup -> Reboot it will work again - when I look at the DHCP client table it is now populated with all my devices. I am on firmware version 2.0.37.
Any help would be appreciated.
thanks
Bruce

Thanks for your help - I believe you may be correct.
I changed the DHCP client lease time from 0 (!day) to 8640 (6 days) and so far no problems this morning. If it lasts another 24 hours I will know for sure.
I don't think there is a newer firmware version than this: 2.0.37.131047

Missing Wireless Devices On DHCP Client Table

I’ll always have three wired devices connected on my router at all times and other wireless devices but I disconnect them when I'm done using them. I’ve recently left two wireless devices connect all the time but what seems after a week or so all my wireless devices stop showing up on my DHCP Client Table. Even though they stop showing up on the DHCP Client Table they still work fine and are still connected to the internet. I already tried rebooting my router and that seems to fix it. I have an E2000 Router with the latest Firmware: 1.0.04 I haven’t had any problems with disconnects or anything. My question is why is this happening and how do I fix it or does the router not support devices been connected for days? Thanks in advance.

There is no fix for this problem as it's not a problem. Maybe your wireless devices don't renew the lease at some point but just keep using the current IP address. Maybe it's a bug in firmware. But as you have noticed it does not cause connection problems. I think very often there are glitches in the DHCP table of various routers.

DHCP Client Table won't reset

Hi,
I am rearranging my router settings, mostly my DHCP Clients, but i noticed the DHCP Client Table won't reset itself and therefore i can't add new static IP's anymore for a specific pc or printserver.
I have a Linksys wireless router WRT54GC.
The error which i receive after trying is "Error: This entry already exists in the Reserved PC DHCP Client Table."
Is this a known bug and is there a way to fix this/clean up the Client Table? Without resetting my modem ofcourse.
Thanks in advance

This is a Linksys user forum. It is seldom you see a Linksys tchnician posting here, unless they post without acknowledging that they work for Linksys. (Which I believe they should have to do, personally. A special avatar to let us know they are Linksys personnel would be all it would take. Unless of course they wouldn't want to be held accountable for their advice )
If you want direct tech support from Linksys, your going to have to call them....good luck!!!

WRT400N - issues with brief disconnects and DHCP client table

Hello,
I recently bought a WRT400N to replace my (seemingly) dead WRT54GS. It worked great out of the box, and setup was quick and intuitive, just like my previous router. It came with firmware version 1.0.10 B19.
I'm having two problems. First, while playing some online games, I'm getting brief disconnects every 2-3 minutes. It's usually just enough to make the screen studder (I'll get a "Connection Interrupted" message for a split second), and then it goes away. It's happening often enough where it's causing issues, though. My computer is connected directly to the router via CAT 6, and the only component that has changed since the issue started is the router itself. To add confusion to the problem, when I do a tracert to something like Google, most of the hops come back fine, but I'm noticing it takes 4-5 seconds before it lists an IP address for any given hop, UNLESS a domain name is specified. The actual columns with the latency numbers are filled in quickly, but the IP address itself at the end of the line hangs for a minute. For example, the final hop, "12 22 ms 24 ms 23 ms od-in-f104.google.com [64.233.161.104]" is displayed instantly, but any hops along the way that just show an IP address, such as "11 27 ms 26 ms 25 ms 216.239.48.190" have a long pause before the IP address (bold) is displayed. Normally I would think it's a problem with the routers along the way, but the delay even happens before it displays the hop to my router's IP - 192.168.1.1. Very weird. I wasn't sure if these issues were related.
The second problem is the DHCP client table in the router's web administration utility. On my old router, the DHCP client table always displayed all computers that were connected to the router (DHCP set to auto). With the WRT400N, I'm noticing only a few of the machines are actually showing up. They're all being assigned IPs without any issues, and they're all able to connect; they're just not showing up in the table. I often check the client table to see who's connected or grab a MAC address when I need to mess with QoS or access restriction, so the fact that some clients are missing is a bit annoying. The old router didn't have this issue.
Thank you.

As you are facing this problem with the Wired Computer, then i think you need to change some settings on your Router. Once you login to the Router GUI, below the Setup tab you will find MTU, which will be set to AUTO,So change it to Manual and change the Size from 1500 to 1365 and click on Save Settings. Once you are done, now try to play the Games and check if you are facing the same problem or not.
If still you face the same problem, then i think you need to Re-Flash the firmware on you Router.. Go to website linksysbycisco.com/downloads .........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop..
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

How to clear dhcp clients table

Does anyone know how to clear the DHCP Clients Table?
I have a WRV54G.
Regards
Solved!
Go to Solution.

I understand this is a very old post, but since I found it when I was looking for the same answer in 2009, I thought I would go ahead and give my $.02 worth.
I have a different router, so this may not be present in yours.
I use a WRT54GLwith firmware version 4.30.7 and finally found on the Status page under "Local Network" a link to the DHCP table. You can click on that and delete the existing IPs.

AirPort Utility 6.0 DHCP client table?

Hey there,
I just started using the 6.0 version of the AirPort utility. It's fancy with pictures and all . . . but . . .
How do I get to a list of the DHCP clients? It eludes me. In the last version (5.6 I believe), I would select my main AirPort and get into the client table in its settings. Now, though, I see a list of the DHCP addresses in use, but it's not listing them all, nor do I see the one that usually gives me trouble.
It looks like my AirPort Extreme and Time Capsule are both running firmware version 7.6; it looks like I can update that but I haven't wanted to disrupt the network yet.
I have a D-Link wireless camera connected which points at the dog kennel outside; whenever I mess with the network it gets a new IP address. I'm accustomed to looking in the table to find where it is, but now it appears I have no table.
Should I revert to 5.6 for that information? I can't find anything in the Help data on DHCP clients.
Thanks. I'm sure the answer is easy, I just can't seem to figure it out.
Stuart

I still can't figure out what the deal is with my Time Capsule. It will occasionally (maybe every 3 days or so) lose its connection to the network and get a yellow light. If I reboot the main AirPort Extreme, the connection is re-established.
At least now I have an IP reservation for it, so I can always just pull up the camera without having to search for its IP address, but the fact that the network breaks up every so often is quite annoying.
Any ideas? I guess I could start a new thread about My Time Capsule Loses Its Mind, Help, but this discussion seems like the right place.
