Sagem 2704n as WiFi Extender for BT Openzone

[#1]

ooops.  One last suggestion, if you feel like it.... you could try increase the frag threashold to 550.
A quick test connecting to "BTOpenzone-B" and "BTWiFi-with-FON" showed the "give me money" page.  But it might not seem any faster?

[#2]

No discernible difference after last Frag Threshold change. Reverted to 1480 MTU and auto/ no value FragThres
BTWifi-with-FON leases are lasting at least 12 hrs without need to re-log-in on landing page (as opposed to 2hr max renew previously) which is great.
Also something in the setup (i'm not mac spoofing) means I need only log-in to BT from one device ethernet-ted to 2704n and all others function just fine. Curious, but i'm not complaining!

[#3]

Ah, I though you would only need to logon with one device.  Its due to the firewall using everything via the mac address - 44:e9:dd:00:00:0x.

Ok. Plusnet have kindly activated my service but not sent another router (as I was told they would) so now I need to roll back to original firmware (or preferably Matty's Rev3B).
I have the .bin at the ready but keeps timing out when I try via tftp.
I've removed password just in case it was a stumbling block but other than that I'm at something of a loss.
Please help.

[#5]

Sorry. To clarify I reset to no Luci w/ paperclip in a moment of frustration at WebGUI firmware flash not working (i assume because it's .bin not .trx?).
Now I can't access 192.168.1.1 at all even though i'm clearly connected (please see attached grab).

[#6]

Don't know a definite solution to the problem, but have you tried rebooting both router then computer?

[#7]

I certainly have.
I've set up http server on Mac in Terminal with this lovely feature:
cd /'ftp folder name'
python -m SimpleHTTPServer 8000
this way you can navigate to any folder and make it an http server at 0.0.0.0:8000
Replacement firmware .bin ready and waiting but without router access via Telnet none of that's much use.

Hello, ooh that a pain...
The telnet disables its-self when you set a web password.  And then SSH is automaticly enabled.
you could try "SSH 192.168.1.1", how ever if that worked.  It means it did not do a factory reset correctly.

P.S. you might want to use the original stock firmware first.  Just to let all the router send its data first, then swap over to the 3A or 3B firmware afterwards.  I suggest this just to make Plusnet servers/logs happy.

[#9]

Another way to get the telnet back:
When the router is all loaded up & running.  Hold the reset for 10 seconds.  It will not reboot, but it will load the telnet.
The next time you reboot, it will erase everything - and also restore the telnet.

I wouldn't worry two hoots about Plusnet servers/logs,just go for which firmware you want. The "possible" issue with connecting with the PN firmware and tr-069 is it may load the PN v2 firmware and that stops http://192.168.1.254/dumpcfgdynamic.cmd from working, don't know what else it messes up (yet).

Hi again gents.
Thanks Matty I've reset router (10 sec hold then on next reboot) now telnet 192.168.1.1 gets me the openwrt page but after calling tmp directory the wget line gives me connection refused.
It should be wget http://"http server IP address"/firmware.bin right?
In my case "wget http://0.0.0.0/code.bin"; or (as worked previously) IP address inc. listening port in wget line i.e. 0.0.0.0:8000

[#12]

Hmm, its probably not talking to the internet.   You could try to login to BT via your ethernet / laptop first.
Or try this:
download this http://techy.16mb.com/uploads/original-plusnet-bcm-image-72731.bin.  And place it into your http server folder like you did before:
telnet 192.168.1.1

cd /tmp
wget http://192.168.1.216/original-plusnet-bcm-image-72731.bin
sync
dd if=./original-plusnet-bcm-image-72731.bin of=/dev/mtdblock5 bs=65536

reboot after the command line comes back.

[#13]

Oh, if your wanting to put the custom firmware directly onto the router now, I cant offer a easy solution.
I'm locked out of my google account (due to the way Plusnet keeps providing almost random public IP addresses).  So I can not upload a nice firmware without instructing you to play with Hex editors.

[#14]

Http server working and .bin showing in 0.0.0.0:8000 directory but i'm still getting:

Matthews-MacBook-Pro:~ mbray$ telnet 192.168.1.1
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.
=== IMPORTANT ============================
  Use 'passwd' to set your login password
  this will disable telnet and enable SSH

Re: Hex Editors I do have Xcode but have no experience using it/ any hex fiddling.
I am using my phone hotspot atm and don't have BT Openzone access anymore, my Plusnet line is now active so i just need this router back to it's normal functionality. Cheers, Matt

ah ok.
when you are saying "0.0.0.0", are you using the real ip address of your PC?, e.g. 192.168.1.106
