Apologies if this is not the correct forum - I couldn't see a specific Spark mobile or fixed wireless page. I just have a couple of questions regarding the fixed wireless service. 

I don't have the Spark 4G fixed wireless myself, but have seen quite a few people with it, and see a massive variation in speeds and throughput. 

For example, somewhere with perfect LOS to a 4G tower, about 1km away, doing a speedtest in the middle of the afternoon would get around 80Mbps. Try and actually download a decent sized file though (in this particular situation it was the LibreOffice installer) and the download speed started at 7-8 MB/sec and promptly dropped to under 300KB/sec and stayed there. Pause the download for a few mins and run the speedtest again - over 50Mbps. 

I've seen similar behavior at different addresses - that is a very extreme example, but the download behavior to me seems like super aggressive traffic shaping.

Does anyone know, or can confirm what the traffic shaping situation is on the 4G fixed wireless? 

I do know of several people who have ditched the fixed wireless and gone back to ADSL too as the speed variation and latency was causing too many issues. Again, this is more info from talking to people who have changed, not first hand, but I find it a bit cheeky that Level 1 Spark helpdesk staff seem to be pushing the 4G service very heavily and in some cases not properly explaining the options.

Thank you. :)
