sycn speeds

hi all these r my stats cannot sycn any faster reboot router and sometimes get2mb? then erboot get 8 meg all in the early morning iam with Vivaciti on llu adsl2+ on obit network is this the fastest my line will go? not got diffrent router to try using a st585v6 firmware 6.2 it is 4 yrs old any ideas or is that my limit cheers martyn

The sync rate determines the fastest speeds you can have on your line. In your case you are syncing at 12,550 kbps downstream. Does that figure vary much?

yes only if i reboot the router rebooted early on about 2hrs ags and got 2mb,then 8 meg, on the 2meg sycn my nm was 26 ,is there a training period on adsl2+ been on it 1 week? cheers martyn

I think Sky and O2/Be do have a sort of training period but that would not account for the wild swings you are seeing.

Do you or could you use RouterStats to monitor your line? See http://www.vwlowen.co.uk/internet/files.htm

12Meg ADSL2+ sync at 27dB attenuation.

I would expect more, given the variations then something may be noisy/loose somewhere in the home wiring/telephone line

Your text talks about sometimes getting 2 Meg or 8 Meg Sync, but both your router stats show 12.5 Meg Sync. Are you sure you are talking about the same thing?

You should get about 17 Meg on ADSL2+ @ 27 dB attn.

yes i did sycn at 2meg with a nm of 28 and 8 meg when i was rebooting the st585v6 router, then stopted rebooting when i sycned at 12 meg ,iam on fastpath nm6 and my nm is very stable at 6 y cant i sycn any higher? this is my sats now

do they look ok? do 0-bit cap sycn or is it my line fastest it will go i have run routerstats lite and is 6nm to 6.5 all night any ideas?traing period? router in test socket and router plugged into mirco filter and cat5 cable upstairs to my computer

They may cap the sync, but if selling it as an up to 24Meg package thats not what they should be doing.

The wildly varying sync on reboots is a sign of

1) Dodgy kit
2) Dodgy wiring
3) Dodgy phone line

I would suggest trying a different modem, you are on a Huawei Infineon MSAN

Dodgy kit ? exchange?
Dodgy wiring? looks all ok here not got a diffrent routeronly the st585v6 got a speedtouch frog looks like a frog silver will that work did on adsl1 will change the mirc filter see if any better
Dodgy phone line phone working ok no noise phone is on the llu package

Using google the 0dB power for downstream is a bug with the speedtouch kit.

Hence why trying different hardware is worthwhile.

By noise I am referring to noise outside the audible spectrum. A phone is very tolerant to small glitches, as is the human ear, ADSL modems are not. Some cope better with situations.

I've found a Netgear DGN2200 stable on what I know is a slightly dodgy line.

In essence you buy different kit and try things, or you put up with it, or get it reported and end up paying for visit if something is found with your wiring.

For example, have you removed the ring wire from any extensions? Is performance better when using the test socket.

ADSL was less affected by things like extension sockets, ADSL2+ is more affected, and VDSL2 even more

got no extensions took the front of to test yrs ago never put it back on ill try a reboot with corded phone out see if it makes adiffence ?is there a newer firmeware than the
Software Release: 6.2.29.2
is that the only firmware? been runing roterstats for 1 hr flat line on 6 not moved

This version of DMT may work with your modem. http://www.2cent.de/dmt/v7/dmt.zip

It would let you visualise the noise on your line.

Time to reboot again...

Router has synced to the 6dB target margin, but somehow picked a low sync speed.

Need another rotuer on line to rule out bugs with the speedtouch.

now this again wats up line or exchange?

Speedtouch firmware can be found here.

which firmware is the best tested one? any recommendtions?

Can't say which from the data

getting error canot up grade firmware have the internet got to be unpuged or iam i doing something wrong?

I always used to disconnect and reset the kit to defaults before upgrading firmware, just remember to backup the config before you start.
Are you using the upgrade wizard that's on the cd ??

Not played with a speedtouch for a while though I've got a couple in the cupboard and an O2 one providing my connection but it's in bridge mode.

downloaded the update wizard still no joy

It's not a branded router is it ie AOL, Tiscali (sure they handed speedtouches out) etc as some of these are hardware locked and require some serious work to unlock.

nope not locked got it myself from pc world, any recommendtions for a good cheap router adsl2+?

Netgear are fairly popular and are easy to set up http://www.amazon.co.uk/Netgear-DG834G-54Mbps-Wirele...

Quite often find decent ones going cheap on sites like eBay.

Odd it won't upgrade, firewalls cause issues with firmware upgrades etc.
DG834GT (broadcom chipset) with Sky branding can be found on EBay for not alot, unlock, stick DGTeam firmware on it and it's a good device.

cheers guys will take a look aroubnd

It means the destination host at address 77.107.129.49 is unreachable and so cannot be pinged.

YES TYVM BTW WHAT IS BRAS, RUNING NETWORK TEST oops sry caps one minute passes test then host unreachable what does that bras ip do? and y do i get packett loss?

tyvm for taking the time to reslove my problem

What makes you think 77.107.176.1 has anything to with BRAS? Is that the BRAS (Broadband Remote Access Server) that is associated with BT's IPStream? In which case it is obviously not something that can be Pinged!

NOT ALL DEVICES ON THE INTERNET RESPOND TO PING.

ALSO SOME THAT DO GIVE PING RESPONSE A LOW PRIORITY.

Thus while ping can be useful, when pinging random locations you need to find out whether that machine is up to the task of responding.

Large chunks of the IPStream/21CN WBC networks are not pingable, or will only respond if under low loads. Why? Because responding to pings can delay routing of traffic, so guess which gets the priority.

hi all thnks for all your input, but it was my st585v6 router
