We have 100/50 connection, which when we got it was around that speed when using the Speedtest.net rough test. We did a bunch of these to different networks as well as to the one on our ISP's network. Speeds varied but were consistently around what I would expect,around 75 to 90 Mbps

Lately we are down to about 25/30 Mbps down and about 35/40 up. This is pretty consistent, whether it be during the day or at 4am, 6am etc. I can understand speeds dropping when there is a lot of load on our particular UFB node, but this seems excessive, and I find it hard to believe everyone sharing our node is downloading all day every day.

Do we have a problem or is this just the way it goes with UFB?

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

UFB is designed in a way that it is difficult/impossible to congest inside of the actual GPON network, Judging by your speeds not matching any possible incorrectly provisioned plans it means the issue is most likely going to be either at your end inside your own network or congestion with your ISP.

Best bet is to confirm its none of your devices by testing with a single device at a time (try a couple), Then refer to the ISP.




Perpetually undecided.

My household is on Mac OS and wifi issues reported in Yosemite was not taken seriously until we got UFB. Turned out almost every time we experienced speed drops was caused by the Wifi and disabling/enabling flexes it

Nothing to do with wifi as its all hard wired. I was wondering if the router has packed a sad, but that seems unlikely. I am wondering if we have been provisioned for a 30Mbps download speed, but then it occasionally goes a little over 30 so maybe not.

If you where provisioned on 30mb service by chorus then you would typically be limited to 10 upload so this doesn't match, ISP wise its not completely out of the question that they are limiting download but not upload however that would be strange and only they will be able to confirm that.

As for router, Yes it is possible but depends on the issue, Factory reset would be the next step for it but not all devices reset to working conditions so unless you set it up yourself from scratch probably best to have the ISP on the line at the time.




Perpetually undecided.

IF you never see over 30mbit download, then it could be you have somehow ended up on the wrong profile. This has happened to me before.

it would be interesting to see what its like running multiple speed tests concurrently. If you get quite a bit more speed combined throughput that would indicate that the profile might be incorrect and having the ISP fix this should improve it.

AFAIK TCP ramps up its packet sizes until packets are dropped then it throttles back and attempts to keep climbing up until it can consistently xmit without packets being dropped.

Orrrr, just downloading a Linux ISO like this one with a download manager?

Try disabling any deep packet inspection rules in the firewall and any parental control stuff. Run a speedtest and at the same time browse between different webpages on your router. If they take ages to load during speedtests then the routers processor is maxing out. And a new router will be needed. Unless you can find out what is causing the extra load.

This has happened quite a few times. Looks like you have just been provisioned with the wrong download speed.

Or... Your router is old and rubbish and you are downloading lots of torrents.

Thanks for all the suggestions, was going to wait until I got to work today to check, but found something more interesting to do than going to work, so maybe tomorrow.

Firewall/router was running at 100/50 when we first went on the plan so unless a software update has it doing deep packet inspection or some other processor intensive stuff I don't think that's it, but we have a spare we can try.

Starting to think its the ISP (un-named until I am sure its them), I do a speedtest direct to their locally hosted speedtest server and its around the 30Mbps mark, yet if I go to somewhere else (I.E Spark Wellington who are not our ISP) that in the past was way slower as you would expect I get about 40 odd? Maybe thats within the margin of variation?

ISP in AK, we are in WGTN.

If I use Internet Download Manager to do this for example, does it matter if I use 1 or 16 simultaneous connections? I assume I am after the download rate i.e in Mpbs?
