well thanks for hijacking my thread!

any ideas why the VMNG doesnt see channel 5?

also, have you any idea why my power supply is making a high pitched squealing noise?

Haven't a clue, if it's not a problem why does it matter?

If it really bothers you go back to the plooperhub!

Its not a problem, but channel 5 was visibly less utilised, I put the dud back in yesterday and it went to channel 6 as well, but it did in the past, only after about 4 or 5 reboots it went to channel 5, but i cant get the modem onto channel 5 for the life of me

to be honest plugging in the superhub once with it connecting to same channel as modem has got you no evidence the channel is still available. You need to manage to get the superhub back on this missing channel or just have to forget it

In my situation I think channel 8 is either gone or unavailable as even the superhub always gets channel 7 now. Luckily for me channel 8 was the higher utilised one so am not that bothered its gone. Personally I think it got merged as channel 7's utilisation has gone up somewhat since it happened but not as high as channel 8 was.

Does the channel you connect to with the modem appear over utilised? If not the modem is doing it's job and putting you on the best available channel.

AFAIK you have never been able to force a channel change with the modem.

the channel i am connected to now (6) isnt over utilised, but is clearly higher utilised than 5 was. I havnt really got the time to be swapping modems about, but I would like the VMNG to connect to 5, as that would be an awesome connection. channel 5 was good enough on the superhub, but when that rebooted magically it sometimes put me onto 6

iv got some time to waste at the weekend, so I will have a play with my toys

does anyone have a clue about the squealing power supply?

Get a replacement power adapter, keep trying until you get one that doesn't squeal. As they don't send them out serarately you will end up with a large POS supply!

the one I received with the VMNG300 was a netgear one identical to the superhub power supply, so iv swapped it over for the one that came with the superhub, so all is working and no squealing!

i now have all the good kit together and all the crap stuff together

I have a few PSUs that make high-pitched squeals, I always figured it was a result of poor quality components used in the stepdown process, a theory added to by the fact the noisest ones also tend to run the hottest.

craig I Was checking the old LE3 thread for something and found my old channel 7 frequency, it does seem although the modem reports channel 7 I am actually on the old channel 8.

Here is my old channel 7 frequency.

http://www.cableforum.co.uk/board/35176947-post369.html

Upstream Channels
Lock Status Modulation Channel ID Max Raw Bit Rate Frequency Power
Locked TDMA 7 10240 Kbits/sec 44000000 Hz 43.9 dBmV

I am now on and have been since docsis2 45800000 Hz

I would have expected if merged for the start to still be 44000000 Hz.

Given my upstream is now looking more shaky utilisation wise I am also curious if I can get back on another channel somehow.

craigj2k12 · 31-05-2011, 17:04

Exactly my problem. I tried for about 1hour 15mins to get my beloved channel 5 back, but nothing, i was even doing the trick with pulling the wire out, then putting it back in when the modem disconnected. However as I I posted on here a few weeks ago around the time of the royal wedding there was an upstream issue which required work on the network and things havnt been the same since. The channels have the same number and frequency on both the superhub and VMNG300, so it definitely the same channel, and if the superhub could see number 5 then why cant the modem?

pip08456 · 31-05-2011, 17:08

Igni has answered that for you previously. If the frequency is the same then it is the difference between CPE's Some start the channel count at 0, some at 1.

whoops

read again, the channel number and frequency matches on both the superhub and VMNG300 i.e. they are the same, so whatever number they start from, they both start from the same one

tonight or tommorow I will be disconnecting the cable a few times to see if the vmng300 finds its way to another upstream channel

i might have to try the superhub just to see if channel 5 is actually available any more, but the modem wouldnt connect to anything else
