Settling in period?

[trickytree]

I had the engineer round on Saturday morning the first call of the day.

Installed superhub and upgraded from 20Mb to 50Mb.
So he left me to fill in some registration website of Virgins and off he goes without leaving me a USB adaptor which I thought would be in the box he left me.
Anyway I call and they are sending me one of those in the post after they check that I am entitled to one!

So I have a PC hardwired to the hub. As you do when you get new speeds you run random speedtests every now and again. Saturday and Sunday at various times of day I was getting 30-35Mb down and about 1.5Mb up. Now the up is due to my area not being upgraded in the upload department I guess.

However I know it is 'up to' 50Mb but 30-35 seems a bit short. So wondering if there is a settling in period for the line/router. I'm a patient man usually but if I have a problem then no point sitting on it for a week or so to see if it is going to improve.

Any ideas?

P.S. Also from my wireless laptop I am barely getting over 20Mb (losing about 10Mb). Expected a drop in speed but not that much. Any techies able to explain that would be nice also.

Thanks

There is no "training period" on cable as there is with ADSL. The 50mb is on docsis3 which is more sensitive to power levels than would be on 20mb. Post your connection stats and we will take a look.

Also, the USB adapter comes in the post

Just seen the p.s

If your laptop is running windows XP the run the TCP optimiser. Google search should find it pretty quickly

If your network adaptor on your laptop is wireless "g" don't expect much more speed. You need wireless "N" for 50Mb.

If your PC is XP run TCPOptimiser on that too.

[craigj2k12]

Don't think the pc is on XP. The default values for XP only allow 10-15mb

The connection stats will shine more light on the problem

Go into the Super Hub page http://192.168.100.1/
Advanced Settings - Content Filtering - Services - then untick Firewall Features & IP Flood Detection.

[craigj2k12]

The default address for the superhub is 192.168.0.1 for the record and the firewall and up flood detection don't make a difference to connection speed. As I said, if the OP will post the connection stats, we will be able to identify the fault

Ip flood detection I meant to put

[trickytree]

Thanks for the replies.
Currently at work but will post my stats when I get back home later.

Wired PC is XP but laptop is Win 7.
Will check on whether it is g or N somehow also

Also I had switched off IP flood detection already as I had read so much about that already.

[pip08456]

Run TCPOptimiser on the PC, it may already have been done when you were on a lower tier but would need doing again for the 50Mb.

[trickytree]

Ran TCPOptimiser and already a difference on the PC which is hitting nearly 50Mb.



Laptop device says 802.11n device but then the little sticker on my laptop says 802.11n/g/b so not sure if it can pick up g or not. May have to be of reading about that as would be nice if I didn't have to have the adaptor plugged in all the time.

Thanks for the pointer.
Here are my connection stats just in case.

stats seem fine. SNR on the lower side, but well within accepted limits.

try a speedtest to the london server, when connected via ethernet cable, if you want to see the magic number "50"

apart from that, you just need to sort that laptop out. you can go onto your network connection folder in the control panel, right click on your wireless network and press "status" when its connected, to see what speed the wireless card is connected to the superhub. if its having problems you can change the wireless speed on the superhub settings to 145mb. some users on here have seen that this sorts any problems, but its fine for me at 300mb

other than playing about with settings you can buy a new N rated wireless adapter

If the laptop is rated n/g/b/ then wireless N should not be a problem.

There may be a driver issue (don't rely on windows update, use manufacturer's website) or settings in the hub.

I've tried to find where this is but i can't find it.

[craigj2k12]

Start, control panel, network connection, network connections, manage network adapters, right click on wireless network and click status. Should say connected then the speed underneath

I'm on Vista here.

I think i've found it now. Mine is start, control panel, network and internet, network and sharing center, then click on view status.

The speed changes from 243.0 Mbps to 270.0 Mbps to 300.0 Mbps.

I was looking around for this last night and on Win 7 it seems to be completely different as I think the nearest thing to what you desribe that I could find was it said something like (guessing here) Speed = 54Mb.

Couldn't find any Status option anywhere but will have another look around tonight
