That's great, thanks for checking.

Looks like it - page 428 of the online users manual says you can restore from a 2926 as long as its running firmware 3.9.1.4 or later.

Back to my other question though - 2 antennae enough? Even the 2926 has 4..

I've installed the 2927 and imported the settings from a 2926.

I'm finding that when I connect the 2927 to my Virgin broadband it can only manage 340Mbps on an Ookla speedtest with the router CPU usage hitting 90%. The 2926 consistently achieves in excess of 520Mbps with a pretty low CPU usage.

I can't see anything obviously misconfigured, but I'm no expert, so I'm fully open to any suggestions!

Thanks.

Do you have anything on?
eg QoS?
DDOS?

Hmm, I'm seeing faster than that on mine with G.Network so it must be capable. So far the best I've seen via Ookla Speedtest is 900 down/800 up.

The only changes/settings I made to the router from default are:

- Bind IP to Mac, added a bunch of devices
- Port forwarding, about 20 or so entries
- Changed some port numbers used for management of the router
- disabled all WAN except WAN1 in WAN -> General Setup.
- enabled IPSec VPN server, as I have a DrayTek 2860 elsewhere that dials-in.
- enabled Data Flow Monitor

Presume you are on firmware 4.2.0.1?

Might be worth resetting to default and gradually manually adding your previous config, and see if any particular step causes speeds to drop? At least, a good start might be to back up your config, reset to default, and see if that gives you the basic raw speed you expect.

Stability-wise, it's been up nearly 80 hours, since I first plugged it in on Sunday.

Thanks for the replies. I've tried a reset to default and then putting in my settings, but that still gives the slow speed. I haven't tried building it up slowly so I'll go that way now.

I don't have any QOS or DDOS enabled.

I do have 150 or so IP addresses in the IP Bind list. I've removed half of them and the speed has gone up considerably. Still not quite up to the same as before, but it has gone back above 500Mbps.
