New installation, download speed never tops 15Mb [ Edited ]

[am9]

Hi, just had a VM install about 10 days ago. I've run various speed tests on my connection none of which top 15Mbs and I'd have though I'd expect to get about 5 times that.

I've tried various computers, a desktop connected by network cable, laptops over wireless and connected via network cable, all much the same. 

This is the latest wired speedtest connected directly to the Superhub (latest R36 firmware).

Can anyone shed any light on why the speed might be as low as this and is this all I can expect?

thanks

Can u post the Hub/Modem Power Levels of the upstream and Downstream.

These can be found by typing in 192.168.100.1 to the address bar in the browser (if its a hub you may need to click advanced settings to view all options).

Modem Username and Passwords are usually root for both.

Hub Username is usually admin and password is usually changeme.

Note that the Hub passwords above are default and if changed by yourself you will need to imput what you have changed to.

Thanks for your reply. I've run another speedtest which now gives 20Mbps, still not close to what I'd expected.

 Down

Power Level (dBmV)    -5.8 dBmV    -4.0 dBmV    -4.4 dBmV    -4.8 dBmV    -5.4 dBmV    N/A    N/A    N/A

Up

Power Level (dBmV)    52.8 dBmV    N/A    N/A    N/A

Is there a way to directly post .pngs here to show the full screen grab?

downstream power levels are kind of low, upstream power levels close to being out of range too as they are quite high anything over 50db on the upstream is close to disconnection problems.

Not true, there are areas of thenetwork you can't get below 50

[boothy_2012]

OK sorry mate i am probably wrong then, jb66 probably does no more than me, should be fine then aslong as they dont go over 56db.

[am9]

jb66, have you any thoughts on why I'm getting c. 15mbps instead of 50 Mbps and is there anything that can be done to improve it.

[boothy_2012]

You could try booting in safe mode with networking and do another speedtest using wire.

If speeds are fine in safe mode with networking, the speed is slow because of programs installed on your PC/Laptop.

If the above post doesn't help using speedtest.net London namesco server then I would ring up and get your downstream power raised

I have noticed download speeds crawling recently so ran a check for the first time in months. For some time I've been paying for an XL package 30Mb and I find the upgrade in my area has taken place so I am supposed to be getting 60Mb.

In fact instead of speeds doubling they have got markedly slower and checkers show me at 11 or 12 mbps.

I actually can't be bothered going through rigmaroles to try and get what I pay for. If I a car was heavily advertised as being capable of 120mph which actually couldn't exceed 25 there would be consequences for the manufacturer. Virgin and other broadband sellers merely flick a v sign at customers and 'regulators' and carry on telling outrageous fibs about their service without penalty.
