Performance expectations on 80/20 not met

[pauloconnor81]

Having 'upgraded' to 80 Mbps service, I expected to get near this. Actual download achieved with ethernet directly into home hub 3.0 with nothing else connected the speed varies between 20-25 Mbps download.

Its been confirmed that there are no faults on line and this is acceptable level, and only if it falls below 16 do I have right to complain.

Very poor.

this is one of the reasons i'm wary of signing up, if i only get 2x my adsl speed and not 10x, then i'd be severly annoyed about paying the extra money for 24 months and would want to go back to adsl.

what's your upload like?

[pauloconnor81]

Upload speed is relatively good, around 16Mbps on a 20 Mbps

What were you getting before?    

Remember that 80Mbps is not guaranteed and is an "upto" figure and the speed will depend on several factors including idstance from cabinet,  line quality,  external noise, cross talk ...

[pauloconnor81]

I was getting the same speed on 40/10 service.

I'm just under 700 Metres from cabinet, which BT says is no issue.

Engineer has confirmed line is free of errors, and testing shows line capability of 61 Mbps, which they get between business and cabinet. Regardless of time of day, I get 20-25 though.

Then you almost certainly have a port fault.

We had exactly the same thing with ours, our line measures capable 90/40 and used to give us 20/8 on 40/10 service. BT said there was no fault. We are about 200m (cable) from the cabinet.

After a lift and shift it is running at 37/8.2.

So be firm and persistant if the line measures fine then the problem is at the other end. 

In our case a very nice engineer took the router and the modem and sat it on top of the DSLAM plugged it in directly and got exactly the same result as we got in the office and proved that the wires had nothing to do with the speed problem. 

I am afraid that it is easier to blame the wires than the cheap rubbish hardware that is being used for the VDSL rollout. My sense is that the % of faulty gear is very very high and that each port needs to be endtested at the time of install. VDSL 2+ should work for quite a few miles over decent quality wires.

If you were getting those speeds on a 40/10 service then upgrading to 80/20 would give a significant improvement on te upstream - potentially hitting maximum but for downstream the improvement would be minimal - if anything.    The line has not changed just bandwidth cap.

However, if te technician ssays the line syncs at 60Mbps then there is the possibility that there is a problem.

How is the modem connected to the phone socket?    How is the PC connected to the router?   Before escalating te issue, you need to be certain that the problem is not at your location.

It's a single PC connected by Ethernet directly to router Which is connected to modem then to line. (Wireless disabled on router)

Have swapped PCS, cables, even routers to rule out problems internally.

Problem is external, not at location, I think. Have not swapped open reach modem, as don't have

Thanks

I guess wired connection is better than using WiFi. Anyone can agree on this?

[pauloconnor81]

Wired connection is faster and more predictable.

Wireless has the possibility of interference from other devices, such as microwaves, it's hard to control the number of devices contending to use the Access Point etc.

In my business, I have five wireless access points around the building. These are all wired back with Ethernet to a switch, and a single Ethernet cable goes from the switch to the router. The router has wireless disabled.

To enable accurate speed testing, I disconnect the switch o router cable, so only my PC is connected to the router by Ethernet.  Means wireless points lose connectivity while I run the tests, but it provides an accurate test result.
