Hi, I was previously using a Netcomm wireless router and it was giving me a maximum bitrate of 3000kb/s (or something like that) and it would give me a realistic speed of 2.3Mbps down but ever since upgrading to the Spark provided modem, these are the stats I'm seeing:

DSL synchronization status: Up Connection status: Showtime Upstream line rate (kbit/s): 952 Downstream line rate (kbit/s): 1906 Maximum upstream rate (kbit/s): 1048 Maximum downstream rate (kbit/s): 2268 Upstream noise safety coefficient (dB): 13 Downstream noise safety coefficient (dB): 13.1 Upstream interleave depth: 0 Downstream interleave depth: 0 Line standard: ADSL_2plus Upstream line attenuation (dB): 26.4 Downstream line attenuation (dB): 52.5 Upstream output power (dBmV): 12.6 Downstream output power (dBmV): 0 Downstream interleave depth: None DSL up time: 0 days 5 hours 31 minutes 41 seconds

Go back to the netcomm then.

At 52dB downstream attenuation you are on a very long line - some modems are better on long lines than others.

That modem was 10 years old and didn't support 5Ghz:P Along with it missing many, many features.

I was assuming that perhaps it would take a few days to adjust but if it doesn't, oh well. I do need that USB port and 5Ghz on my modem.

Your on a borderline connection, Make your choice of speed or features. or go with the alternative soultion and turn the netcomm into a modem, let a decent router/wireless AP offer you the "features" you seem to crave. Best of both worlds.

Yep. Sounds like the best idea. Thanks.

Thought ild follow up with pointing out what i did in a similar situation - having had RBI upgrade already its LESS of an issue now but theory still stands.

I went the alternative route, dived into a pfsense box. Transparent proxy, decent Queuing on the upstream channel - Downstream its already hitting you anyway, Benefits are less important here.

Found the best modem for my dslam and line. Ran in bridge mode, Found the exact configuration that worked best for my connection (PPPoA/PPPoE Vlan10/DHCP Vlan10 - Some of these arent officially supported by my isp but do work.)

it is 11pm, there is not much traffic on the network at all (mainly torrents, and nighttime trawling.. by the looks of things) but raw hitrates are actually pretty decent. Certainly on Frequent things - EG Nvidia updates that Everyone pulls there is huge benefits. Worth considering the uptake of ssl will make this less viable over time though.

Cache information for squid:
Hits as % of all requests: 5min: 14.3%, 60min: 6.0%
Hits as % of bytes sent: 5min: 40.0%, 60min: -3.7%
Memory hits as % of hit requests: 5min: 0.0%, 60min: 26.9%
Disk hits as % of hit requests: 5min: 0.0%, 60min: 50.7%
Storage Swap size: 23702744 KB
Storage Swap capacity: 90.0% used, 10.0% free
Storage Mem size: 813336 KB
Storage Mem capacity: 99.3% used, 0.7% free
Mean Object Size: 338.19 KB

Given this is going to extremes, but all boils down to the point being you have a static situation of simply your line is long. Sometimes the solution there is a Alternative medium, sometimes it is to Squeeze out what you can.. Have a fiddle, who knows what miracles you can preform!

Just out of interest what does http://chorus.co.nz/maps say about your connection?

Yup.

As you can see above, the upload has dropped but downstream has gotten a healthy boost.

Either there's an issue with your address on Chorus maps, or a line fault. There's no way in the world of getting >10Mb/s with 52dB attenuation, the line's just too long.

Chorus maps are hardly accurate. Everyone around me is complaining about the speeds and I'm connected to an exchange really far away so again, the Chorus map is wrong.

or there is a issue with the cable everyone is connected too.....

chorus base their maps on distance, so generally speaking you should be able to get what that map says you should get, if you cant there is more than likely an issue somewhere

Sorry but I know that's not the issue.
