Hi,

just thought i would share my experience of what the recent Auckland power cut did to my VDSL speeds and have question which i may already know the answer to! So my modem was syncing at about 31up and 7 down and 5 ms ping, had been for over 30 days as i tend not to switch off. Then on Sunday Morning when my power was restored, (our area one of the first) i noticed my sync speed had shot literally through the roof to 46 up and 7 down, i checked speed test as i thought ping would be affected but no , ping was my usual 5ms. Now my initial delight was of course tempered with the fact that this may be because hundreds of other connections were still out and i was just a lucky one taking all their bandwidth...correct?
Sure enough a DLM reset this morning took me down to 33/8...no complaints as this is a speed i am comfortable with and does all the things i need it to , (lightbox, Netflix PLP and gaming etc) and i kind of expected it to drop anyway..but my ping has gone up to 21ms, i am guessing another DLM will drop this at some stage?, just wondered if anyone else had experienced a similar thing.

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?

Yup, many experiences like this with VDSL during power cuts have come up on these forums; Less crosstalk and interference from other electrical sourcesm means higher sync during a power cut, and possibly for a time after.
