(ask) WRT54GC Static DHCP client name always "unknown"
I use WRT54GC for gateway for my internet connection. I have several wired computer that connect to switch that connet to WRT54GC. I have set Static DHCP as in manual book and name each MAC address. But in DHCP client list the name always show "unknown". Anyway to fix this? Thank you.

The router DHCP will not show client using Static IP in the network .....
If you are using "Obtain IP settings" .... then the IP address ...computer name & MAC address ... will be there ...

WRT54GC Static DHCP listing issue
Hello:
I have the latest firmware installed (1.02.8) and I am running into an issue:
I currently have my WRT54GC to act as a DHCP server with 100 clients; I set each of my PC's to DHCP, but the WRT54GC will serve the same IP address to each PC ("Static DHCP"). I currently have seven MAC listed in the static DHCP list, but when I attempt to add another MAC and save the settings, it times out. This has happened consistently where it appears only seven MAC's are allowed. I can edit the existing seven without an issue, but adding any more PC's times out the router.
Any ideas? I have flashed the router a number of times to no effect.
TIA.

Ok,first - try to delete 7-th MAC address and IP,then click "save settings"
When it finished with rebooting,connect and try to fill the 7-th MAC with IP Address.
It should work!!!
That happening,cou'se first you should free the MAC Lock in router's memory,reboot to free it and delete from memory,and then you can fill new MAC Lock function.
Good Luck!!!

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,
SteveI 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.

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... -
I want to understand the differences in the way you can reserve a static address for a device on the network. I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss. I'm not sure if this was in fact correct or just happend to work. I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.
A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
xx:xx:xx:xx:xx:xx
Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
Open System Preferences (gear icon on the dock)
Open Network
Click on Ethernet
Click Advanced at the lower right
You may be able to edit the DHCP Client ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac. -
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). -
WRT54GC - Port ranges, triggering, static DHCP.
Recently got a WBR54GC router and it works great on the network. I don't use it wirelessly, but hey, it was cheap, may aswell go for it! The firmware though has been less-than comforting. It works, but there are a few gaudy bugs.
Port range forwarding refuses to work on ports higher than 32768, and ports higher than 20000 are often very flaky to get the router to properly take. After saving the settings the port range often appears vastly incorrect or even impossible (ports 104824 to 0 for example).
Second comes port triggering, which puzzles me. There's no option to set if the trigger port or the forwarded range should be UDP, TCP, or both. It simply asks for two ranges of ports, one to monitor and the other to open, and it only seems to do this over TCP ports. Currently, I swap the computer's IP back and forth in the forwarded ports page to the computer I'm using. Its a fix but its a pain in the ass.
Finally comes static DHCP, the settings page of which seems to not properly remove settings. After I entered an IP/MAC combination in the first few avaliable boxes I went back to change one. The router then told me that the DHCP client I entered was already in the table? Strange. I opened the static DHCP page again and now there was nothing! Alright, enter all the details again, save settings. It again told me that the DHCP client was already in the table. Close, open it again, still blank. I tried to save the settings with the DHCP client table completely blank thinking this could correct it. Funny, I'm still entering duplicates even though the page is blank. I ended up recording my settings and doing a factory reset to wipe the table correctly.
Firmware Version: v1.02.8, latest of course. Searching these forums, I did manage to find a thread that mentioned the port range forwarding issue, the first one I talked about. The problem is the Rapidshare link given to a beta firmware was dead. Since then I'd been looking for this new firmware beta to hopefully resolve most of these issues, but without much luck.
Any help greatly appreciated.This problem is an obvious firmware bug.
Why the hell do all router companies sell a professional looking product, but with firmware that looks like a group of random twekaers and hackers threw together?
No offence. My D-Link router has misspelt words, which is absolutely sad. -
I have a SunBlade using Solaris 9 with the DHCP client. I am requesting the DHCP information from a w2k box that is sharing my DSL connection. I cannot seem to get the configuration to provide a hostname (always comes back "unknown"). Any suggestions?
Hi there,
Edit the file /etc/init.d/network and change the line that reads
"dhcp") hostname=`/sbin/dhcpinfo Hostname` ;;
to
# "dhcp") hostname=`/sbin/dhcpinfo Hostname` ;;
"dhcp") hostname=`/usr/bin/cat /etc/nodename` ;;
Then, edit the file /etc/init.d/inetsvc and change the line that reads
hostname=`/sbin/dhcpinfo Hostname`
to
# hostname=`/sbin/dhcpinfo Hostname`
hostname=`/usr/bin/cat /etc/nodename`
Save the files and reboot the system. The system's hostname will be the
entry in the file /etc/nodename.

I'm thinking of implementing DHCP service on my Xserve. I see that when an Airport Extreme Base Station runs a DHCP server, you can create static maps with the individual computers/clients identified by their DHCP Client ID, something which I would find useful. AFAICT, this is not possible in Leopard Server's DHCP server, but it seems so unlikely that the AEBS has MORE functionality than Leopard Server.
Am I right, or is it possible to map static IP addresses by Client ID in Leopard Server?Camelot wrote:
Leopard Server does support static maps - it's right there in the Server Admin GUI.
Yes, I think I mentioned that.
However it's based off client MAC address, not Client ID.
So that's a no then.
Which means an AirPort Extreme Base Station has greater functionality than Leopard Server:-( -

RV180W with 1.0.2.6 Firmware - Static DHCP problem
Today I installed the 1.0.2.6 Firmware on a RV180W. I only have now two problems regarding the Static DHCP support in the GUI.
1. Via the Networking > LAN (Local Network) > Static DHCP I have no buttons to Add a new static Lease.
2. Via the Networking > LAN (Local Network) > DHCP Lease Clients I can thick a Lease and click on Make Static IP. The result is an error: Operation failed.
Is this a bug or am I doing something wrong?RV180 f/w 1.0.4.14
Static DHCP page – missing buttons Add, Edit, Delete since some f/w update.
Apparently Cisco has changed syntax since some f/w version I don't remember.
Fix:
1. Backup unit's settings. Use some editor to check that the syntax for the section DhcpfixedIpAddress is correct in the configuration file. The main clue is a new variable "Name". An example bellow displays 2 lines in Static DHCP page. If necessary make changes most likely including upper/lower case conversion for MacAddr and the lines order.
2. Change checksum to 0.
systemConfig[1]["checksum"]="0"
3. Restore unit's settings from the edited configuration file. I have got missing buttons back only after the above procedure. Any other suggested solutions didn't work for me.
Correct syntax for newer firmware:
ifStatic[4]["SecondaryDns"] = ""
DhcpfixedIpAddress = {}
DhcpfixedIpAddress[1] = {}
DhcpfixedIpAddress[1]["MacAddr"] = "bc:ee:7b:e3:3b:0a"
DhcpfixedIpAddress[1]["Name"] = "Computer01"
DhcpfixedIpAddress[1]["IpAddr"] = "192.168.1.100"
DhcpfixedIpAddress[1]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[1]["_ROWID_"] = "1"
DhcpfixedIpAddress[2] = {}
DhcpfixedIpAddress[2]["MacAddr"] = "00:15:e9:6a:0f:15"
DhcpfixedIpAddress[2]["Name"] = "Unknown"
DhcpfixedIpAddress[2]["IpAddr"] = "192.168.1.101"
DhcpfixedIpAddress[2]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[2]["_ROWID_"] = "2"
DhcpLdapServerInfo = {}
Old syntax incompatible with newer firmware:
ifStatic[4]["SecondaryDns"] = ""
DhcpfixedIpAddress = {}
DhcpfixedIpAddress[1] = {}
DhcpfixedIpAddress[1]["IpAddr"] = "192.168.1.100"
DhcpfixedIpAddress[1]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[1]["_ROWID_"] = "1"
DhcpfixedIpAddress[1]["MacAddr"] = "BC:EE:7B:E3:3B:0A"
DhcpfixedIpAddress[2] = {}
DhcpfixedIpAddress[2]["IpAddr"] = "192.168.1.101"
DhcpfixedIpAddress[2]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[2]["_ROWID_"] = "2"

E4200v2 - DHCP client list NEVER displays
As the most expensive and hyped "consumer router" at the local big-box stores, and after already returning a Netgear N600 that appeared to be defective, I had high hopes that this router would work properly and I could stop fooling with router settings and move on to real work. And I'll acknowledge that for a lot of folks this router will probably be fine. I didn't do any speed measurements or methodical testing, but it seems pretty fast and using it for more than three weeks it seemed reliable. However, it had several issues that were maddening and ultimately for me, unacceptable. Summarized as follows:
> The DHCP client list NEVER displays all the clients connected on my network, no matter how many times I look. These clients are actively transferring data, and I can download free programs from the web that report all clients reliably. Why is this so difficult??
> The logging feature is ridiculous - it often didn't log events that I knew had occurred, and even when they were shown, you would only see an entry if you checked the log very quickly after the event (some sort of "auto-flush" function that makes the whole feature pretty useless).
> The previous issues are annoying - but this was the deal-breaker. I could not connect to an OpenVPN device on my network through this router. I could connect to the device locally, I could connect to other devices remotely through other forwarded ports, and I could see in the log (if I looked quickly enough) that the router was seeing the connection attempt to the OpenVPN device, but it was getting blocked. Many hours searching forums and experimenting with router settings / firmware updates did not help.
> In the pursuit of resolving the third issue, and with very low expectations, I contacted Linksys tech support. This proved to be a complete waste of time. After working through the front-line guy who only knew how to look through the User's Guide, I was connected to another person who was even more clueless and was almost robotic in his hard-coded sequence of attempts to guide me through silly procedures that had absolutely nothing to do with my problem. After again asking if I could speak to someone that might actually understand the issue I was put on hold for more than 20 minutes, at which point the call was disconnected (I think this means they hung up on me).
So once again I'm returning an expensive router that doesn't work properly and will be trying something else. It shouldn't be this difficult.With reference to your post I would like to know that does all the client devices on your network runs on DHCP or some of them have static IP address as well? The devices which are running on static IP address will not be displayed in the DHCP client table.
Regarding the logs that are not being created on the router for any event that takes place could be because of the reason that you might be using another router or a gateway before your linksys router.
As far as your VPN issue is concerned please try to disable the firewall of the router and then try to connect to the open VPN device because this router acts like a VPN passthrough.

How to setup default gateway in a DHCP client. The default gateway will be the Ip address of the server that has RRAS installed, hence routing cabalities.
Hi Bill,
Thank you for replying back...Yes, I was actually asking how do you set the default gateway address on the DHCP server?,
I believe I got the answer below:
To configure the DHCP default gateway option Click Start, point to Administrative Tools and then click DHCP. In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Scope Options Click Configure Options, check 003
Router, type the applicable Server name and IP address, and then click OK.
Thank you -
DHCP client does not work poperly after systemd and Gnome 3.6 upgrade
Upgraded my system today from Gnome 3.4 to 3.6 (and systemd was updated as well), and since then acquiring an IP address using DHCP does not work anymore.
I am using IPv4 only internally, but neither dhclient or dhcpcd manages to get an IPv4 address.
It seems like IPv6 is priority one, and beacuse there is no IPv6 DHCP server available NetworkManager aborts the whole setup process.
To make sure that IPv6 should not be considered, I have changed "method" in NetworkManager to "Ignore" for IPv6.
I have also tried to downgrade NM to 0.9.6.0 from 0.9.6.4 (since that version works on another, not upgraded, machine), without any result.
Also switched dhclient to dhcpcd, without any result.
The machine is a "pure" systemd machine.
DHCP works for other devices in the network.
Versions:
systemd 195-2
NetworkManager 0.9.6.4
isc-dhclient-4.2.3-P2
I have no issues on a system where following versions are running:
systemd 189-4
NetworkManager 0.9.6.0
dhcpcd 5.6.2
Log: http://pastebin.com/2wMC0JLeThink I have identified the issue now.
Neither dhcpcd or dhclient is sending the host name properly to the DHCP server anymore. I had an IP address reserved in the DHCP server for my host and after deleting this reservation my host is able to acquire an IP (dynamic) address. The reserved static address could never be acquired.
Conclusion: dhclient and dhcpcd is not sending the host name as before, causing the DHCP server to get stuck (while waiting for the host name) whenever a NIC with a reserved IP address is requesting an IP address.
Downgrading the dhcp clients has not yet worked, so there might be some underlying component that is causing the problem. ath5k? systemd? -
AirPort Extreme (n model) doesn't show all DHCP clients in client list.
Hi all,
Wondering if anybody can confirm or deny this occurrence. I noticed that when plugging DHCP clients into the ethernet ports, those hosts do not show up in the DHCP client list. They do appear to get a valid address and work fine, however. I still intend to test whether or not I can assign a static IP to the ethernet client MAC addresses, but I assume that will work fine as well.
In my opinion, if this is confirmed it should be addressed as a bug (albeit minor). Otherwise I'm very pleased with the new Extreme, by the way. Other issues that I don't like are more a matter of convenience than necessity.
Mike
MacBook Pro Mac OS X (10.4.8)Ditto to all of the above, but I've got another, maybe related, question.
I have my HP printer hardwired to the router. It is set for a dynamic IP address, so the question of a static IP not showing up isn't the issue.
My problem is that I can't get the client ID to show up in the list. The MAC address is there, the IP address is there, the lease time is there. But no matter what I reset, either on the printer or on the router, I can't get the printer name to show up on the list.
If I pull up the printer in a browser window, it shows the name. I've even tried changing the name a couple of times. Nothing.
No, it doesn't really matter, it still works fine. But it's annoying to me.
