Pioneers with that particular hardware and if using the monitoring/filtering aspects suspect you are pushing the CPU to its limits, hence slow speeds.

Notice they managed a WAN to LAN throughput of just 78 Mbps and the date of the review, i.e. in its day this was not bad but now is distinctly slow, and if you have additional filtering I am not surprised your speeds are slower.

One thing to check, make sure the any QOS settings have been updated, since its easy to forget you've set maximum limits previously and may have not cleared those settings hence limited to ADSL2+ like speeds.

To be frank its time to determine what features you need and maybe get a new Draytek with the same features but a much better WAN to LAN performance.

We opted to put the Gigaclear router in bridge mode to enable us to continue using our existing Draytek router. This provides more sophisticated facilities for monitoring and controlling use of the connection.

This is your problem.

The Draytek can do 70mbps+, but not while monitoring and controlling the connection. Filtering etc will destroy your throughput as it means you are no longer able to offload anything and it all has to go through the CPU.

You need something bigger, I would suggest looking at Sophos UTM, or a PFsense box with snort or something for filtering.

Alternatively if they are happy with Draytek then at least a 2862 which offers 400Mbps of firewall performance.

I tried to use one of those routers in my business for my FTTC connection. With absolutely everything turned off it could manage about 30 - 50Mb with the filtering turned on it managed about 12Mb.

We swapped it out for a pfsense box which has the link running at it's stated speed. I imagine your hardware is limiting your connection in a similar way.

Thanks

Yes, something on a cheap PC will go much faster than the router; I imagine (for a school) web filtering is probably the order of the day so Sophos UTM, or Untangled (which can run in transparent proxy mode) to the gigaclear router may well be best.

You may just be able to throw a second network card in an existing PC you have kicking around.

An older Asus e.g. RT-N66 would easily handle 100mb/s or maybe think about implementing a Ubiquiti solution including wifi.
