I'd suggest you consider putting the router on an uninterruptible power supply, it can help in many ways.

Seconded.

UPS on order

Noise Margin:    6.0 dB    13.0 dB
Attenuation:    63.0 dB    31.5 dB (actual Att is (at 300kHz):    73.7 dB

)
Output Power: 16.5 dBm 11.9 dBm

Time Since Last Boot: 2 days 22:01:32

IPprofile still 750K

It will probably take five days to change I'm afraid.

KeG123 · Feb 08, 2011, 19:20:29

The thing is,when I get the UPS I'll have to unplug, reconnect etc

Rik · Feb 08, 2011, 19:21:49

You will. Plug the UPS into the mains first for 12-24 hours before you make the move.

KeG123 · Feb 08, 2011, 19:45:00

Training data looks good to me so far - am I right ?

Rate Max1 Max2 Max3 Mgn1 Mgn2

1280 1280 952 952 6.0 6.0

Lance · Feb 08, 2011, 22:34:27

The margin looks good at 6db so hopefully the line will remain solid.

Aaron · Feb 08, 2011, 22:58:29

Sorry to barge in, but what's a good cheap UPS for a router only? I have an APC UPS already for the PC, but that's at the other end of the room and getting a 2nd one of those is a bit OTT and costly.

Rik · Feb 09, 2011, 09:57:03

It will stop the router dropping out due to mains fluctuations, Keg reported that he's subject to occasional cuts.

Polchraine · Feb 09, 2011, 10:41:00

Thoughts about using a UPS for the modem and router.

UPSs use a switched mode power supply (SMPS) to charge the battery or capacitor bank and when power goes off a second SMPS which is normally idle switched in to provide the required mains output - some UPSs will always provide the output from the second SMPS.

Given there are two noisy devices close by, how much shielding is around the case to stop noise? It could have an adverse effect on the noise level in the received signal causing degradation and lowering of sync speed.

They will claim the output is sine wave - but they are often a set of discreet levels which approximate to a sine wave - smoothing will clean it up a little but when the non-sinusoidal supply hits the power block for the modem/router it can again have an adverse effect causing local noise.

Rik · Feb 09, 2011, 10:42:46

It works for me.

KeG123 · Feb 09, 2011, 19:18:35

I went for this one

Rik · Feb 09, 2011, 19:20:29

That should be fine against power cuts.

For your connection, the acceptable range of speeds is 200-1000 Kbps.
Additional Information:

IP Profile for your line is - 750 Kbps

Steve · Feb 10, 2011, 18:48:34

When you've had 5 days it should move up to 1,000 kbps

The thing is, my new UPS is here (charging up) so won't be connecting that up til me speed goes up !

Rik · Feb 10, 2011, 19:04:34

Definitely worth waiting.

Download still at around 740K so I guess IP profile is still 750K (cant check, BT tester playing up at the mo)

Looks like we had a power cut in the night (which we do occasionally in bad weather out in the sticks ), so that hasn't helped.At least 2700 re-synced 1248

You can check the current profile for your line by logging into your AAISP Broadband Control Panel and the current profile is displayed next to your phone number on the line highlighted in green.

If you click on your phone number, you move to the line diagnostics page and can read off any automated profile changes, such as 27 Jan 04:32:07 BRAS 4M/828K to 4½M/828K, Opt In, 2011-01-26 03:1... -BT-

Although you can turn interleaving on/off, and change many other line management options yourself in the panel, touch nothing until your 10 day training period is complete.

Oh yes, this is a different thread

KeG123 · Feb 11, 2011, 16:31:03

Not a problem, but for a split second I got very excited thinking I could tweak my own connection

Rik · Feb 11, 2011, 16:51:03

Careful, we'll have to get Jill to give you a bed bath.

Profile still at 750K so I guess its stuck

At least it will make a change asking for a 750 stuck profile to be fixed rather than my (previously) normal 135

lozcart · Feb 11, 2011, 17:59:55

I'm sure my profile only shows a change on the BT speedtest if I force the router to reconnect.

Rik · Feb 11, 2011, 18:00:36

Leave it till the morning, then force a re-sync (time to put the UPS into use). That may force the change.
