What does this mean

[Notthisagain]

Hi guys. Can any gurus tell me what the following means and how to fix it? First is a Hyperterminal capture:

the first log in hyperterminal is the modem trying to acquire a frequency, if you flashing you need to copy this into terminal

cd \cm_hal
scan_stop
cd \

or log into the modem (192.168.100.10) to change the mac there

the second log is the modem saying it hasn't got the frequency, when/if its set up right it will take around 5 mins to lock onto the correctn frequency

[Notthisagain]

Is it possible that the flashed modem cannot lock onto the same frequency my subbed modem is using? Basically, I got the frequency and upstream channel id from my subbed and put it onto my flashed. Technically this should work right?

Also, what does that command do that you gave me?

[/24]

You dont need to put in the upstream parameters they will fill be obtained automatically when you have locked your downstream frequency. Look up the frequency for your area it will be the same as your subbed. Once you have put that in leave it to work out its own upstream. The commands shown above stop the modem scanning for a frequency. This is usefull when you need to use the modem console to edit some stuff and you dont want loads of scrolling text

Thanks mate. So yeah i've already put the same frequency my sub uses into my flashed modem but i'm still getting this. Here's the command I used:

cd /cm_hal
scan_stop
cd /
cd \non-vol/halif
mac_address 1 REMOVED
usb_mac_address REMOVED
cm_tuner 14
annex_a
cm_annex 3
cd ../docsis
ds_frequency 331000000
enable bpi false
write
cd \
cd \non
cd msg
user_name root
password root
write
cd /
cd \non
cd msg
http_admin root root
write
cd /
cd snmp
view_v1v2 Noaccess
yes
cd /
cd \
cd non-vol
cd msg-log
telnet_ipstacks 2
write
cd \
cd non-vol
cd snmp
max_dload_tries 0
write
cd /
cd \

Why is it not locking onto that frequency?

Btw these were executed via ethernet through Hyperterminal, that's ok right? I don't need max232 for it?

[badboy_uk]

dude i had the same problem just make sure u have the settings right and freq
wot area are u in?

[G77]

if its hax, make sure the box you input the freq in goes green and then save

[Notthisagain]

I'm in Ex Telewest area cable.grths using same frequency as my subbed - 331000000

It's got Sigma-X2 on it with Fercsa 13.5.

One final question. The MAC i'm using was sniffed from a different UBR using a Webstar modem (i'm using an ambit 200). Does it have to be an ambit mac i use? I've sniffed some macs from my subbed 256, will these work?

[G77]

any mac, now all the probs have sorted themselves out im putting any old mac and config in
