[Freebox] DHCP Lease Renewal Solved

Question

Hello,  It happens quite often that the Freebox fails to renew the DHCP leases. In fact, I say "quite often," but I feel like it's every time multiple computers are connected at the time of renewal.  The solution is simple, just reboot the Freebox. But the problem is, sometimes I'm not physically at home and want to connect to my computer... Or I might not have access to the Freebox (well, when there are guests over, they take over the living room, and on Sunday morning, I'm not going to wake them up for that :p), or I might not feel like rebooting it, for one reason or another. And so, this simple solution doesn't help me.  This problem occurs even though I’m supposed to have a "permanent" lease and a fixed local IP (otherwise, I wouldn't be able to connect from outside for sure). Here, I admit I don't understand what could be happening! Why does it feel the need to renew my lease? :'( Would you have an explanation, and even better, a solution to my problem?  Additionally, I would like to know if it's possible, under Windows XP, to enable the DHCP service only to obtain the DNS server address, and not for IP address allocation (that way, I can set a local IP on my computer without asking the Freebox's permission, and poof, no more problem!). When I uncheck "obtain my IP address automatically" in the TCP/IP configuration screen, I can no longer check its DNS equivalent… Is this a structural limitation of DHCP, a silly limitation of Windows, or a silly limitation of the interface? (And in the latter case, is it workarounds, for example, via a "shell" command?)  Thank you in advance,  Xavier

Hello,  Yes, I know that I can set static DNS, but I don't want to! On the contrary, I want to set a static IP while keeping the DNS provided by my FreeBox.  Otherwise, I did try last time to force the lease renewal with the ipconfig command, but unsurprisingly, it doesn't change anything since the FreeBox is already trying to do it and failing.  Moreover, it seems to me that my lease was permanent, as indicated in the NAT configuration interface of the FreeBox, when directly associating the IP to the MAC address of my computer (well, the wifi card)... I can't check right now because I'm not home (and I don’t know my Free credentials by heart :) )  Thanks anyway!  Xavier

limitations ... limitations. yes, you can very well hardcode the DNS server addresses. even if you are on DHCP: their DHCP server is not required to provide the DNS: go to advanced, DNS tab. the lease renewal: normally should not be a problem. Why do you say you have an infinite lease: that is not something that can be set on the FBX to my knowledge. do you know ip config /release and ip config /renew to renew the lease? -- and ... Voili Voilou Voila !

Well, I want to avoid DHCP because it systematically crashes when renewing leases, about once a week... I then have to reboot my Freebox, which isn't too much of a hassle, some might say, but there have been times when I couldn't access it... But if someone could give me an idea or a hint to fix this problem, I would be very happy with my DHCP!!

If you are on Windows, have you checked the event log to see if there are any error messages regarding DHCP?  -- “Life is short - You need Python” -- Bruce Eckel, member of the ANSI C++ committee

Thank you!  So, I found two events that could be related to my problem during the last identity crisis of my PC: Event Type: Information Event Source: Tcpip Event Category: None Event ID: 4201 Date: 10/21/2006 Time: 07:44:40 User: N/A Computer: YOUR-F14AC45099 Description: The system detected that the Broadcom network card... - Packet scheduling miniport was connected to the network, and initiated a normal operation on the network card.

Event Type: Warning Event Source: Dhcp Event Category: None Event ID: 1009 Date: 10/21/2006 Time: 07:44:44 User: N/A Computer: YOUR-F14AC45099 Description: A network error occurred when attempting to send a message. The error code is: An operation was attempted on something other than a socket. For more information, please refer to the Help and Support Center at https://support.microsoft.com/en-us Data: 0000: 36 27 00 00 6'..  The "Help Center" in question knows nothing about this. The "operation attempted on something other than a socket" seems, uh... mind-boggling to me: I imagine Windows trying to connect: "Come on, screen, connect me to the net!" :D  Anyway, I can see that there was a problem with the DHCP, but I have absolutely no idea what it means or how to resolve it...  Thanks again!  Xavier

An operation was attempted on something other than a socket.  ???  which idiot programmer has.... :-. ?  I don't see how to solve this, sorry.  Have you searched for this error code on msdn.microsoft.com? It's Microsoft's knowledge base.  Also search using the event ID.  -- “Life is short - You need Python” -- Bruce Eckel, ANSI C++ committee member

Hello,   I have a temporary connection (for 10 days) how can I switch to a permanent connection so I don't have to renew every 10 days?  Otherwise, how can I "reset" the internet connection once the 10-day lease has expired?  I can connect by plugging the cable from the Freebox into my laptop, but the Wi-Fi isn't great...  I'm on Vista, and my roommates are on XP; they don't have this problem (I don't know if that has anything to do with it...)  Thanks in advance!  Mat

I don't feel like my Wi-Fi coverage is bad because when I have a lease, the connection works really well. And actually, I think my lease doesn't renew automatically, it expires and bam, no more connection!!   Anyway, I'll try that because my lease expires tomorrow anyway...  Is there anyone among you who lives in Marseille by any chance...? ...because from what you're telling me, I can't get anything (actually, I'm printing your responses and one of my roommates is trying to figure it out...)  Anyway, thanks for your quick responses!

Hello, I also have problems with lease renewal: in the event log, I find the error:  "The lease for the IP address 192.168.1.12 for the network card with the network address 0019D1E13949 was denied by DHCP server 192.168.1.1 (it sent a DHCPNACK message)."

Hello So I don’t understand anything about my IP First of all I called Free to switch to dynamic IP and they directed me to configure my router Here is its configuration >Freebox IP > 192.168.xx.xx. >DHCP enabled (which logically means I’m indeed on a dynamic IP) >DHCP start 192.168.xx.xx. >DHCP end 192.168.xx.xx.  I was assured that I was indeed on a dynamic IP. After rebooting my Freebox, I connected to the site >>>>> http://www.monadresseip.fr/ to find out my IP that is visible on the net and here is the IP it displays >>>> 82.231.xx.xxx this IP is fixed even after rebooting the Freebox or anything else, I would like to know where this IP address comes from as it is not even configured in my Freebox or on my TCP/IP  Thank you for your help

sebsauvage · Answer

This IP is fixed even after rebooting the Freebox.  It's not you who chooses the IP address, it's Free. And it turns out that with dynamic IPs at Free, the IP address hardly ever changes.   I would like to know where this IP address comes from, which is not even configured in my Freebox or in my TCP/IP.  It's your public IP address (internet) assigned by Free to your Freebox. Addresses in 192.168.x.x are private addresses (local network). The Freebox routes packets between the two networks (internet and your local network).

Ruze · Answer

Ok, so basically I can't do anything to be really on dynamic IP with an IP that refreshes with each connection there are going to be Freebox interruptions! thanks for your help

sebsauvage · Answer

Okay, okay, so basically I can't do anything to actually have a dynamic IP with an IP that renews with each connection.  And no!

If possible,  In the Freebox settings, you are on DHCP in a range from 192.168.0.1 to 128 for example. In the permanent leases, you put your desired FIXED IP address and your MAC address. Of course, if you want a FIXED IP, you should set it outside the DYNAMIC range; that is to say 192.168.0.129 for example.
