Very slow speeds on Wan interface

[bowlsys]

Hi
I am a complete newbie to Opnsense.
I have 3 interfaces (Wan,Lan,Opt1) all are working, the Wan I/F is DHCP from my ISP.
The problem is the WAN is very very slow (I have gigabit form Virgin Media in the UK).
How do I set the interface speed on all interfaces and/or check their current settings ?

I think the attached is what you want....Thanks for the help

LAN on 100 Mbps, maybe that's the chokepoint? I can't see what WAN is syncying at. You want to see the:

Code: [Select]

Media: XXX baseT <full-duplex> value. 1000 is Gigabit. Lan as you can see is being synced at Megabit setting.

Sorry to seem stupid but how do I make the changes?

[cookiemonster]

No no, you can't with changing settings. These are the detected values. If they are wrong, there's something at physical level or drivers potentially. So you first need to be sure the interfaces are indeed gigabit and the cables are Cat 5E or over (if I remember correctly).

Edit: correcting a spelling mistake.

Most importantly considering the cables: they must have all 8 wires for Gigabit. There are still some historical ones around that only have 4 which is enough for up to 100 Mbit/s. So people tried to save some material back then.

you know, I have a bunch of spare cables and over time I had not taken out the older ones and indeed were a head scratch for a syncing issue until I stopped to look at them. Doh! moment for sure.

Have just ordered 4 new Cat6 cables just in case, arriving Friday

meantime in readiness, it would be useful to post

After further investigation it appears the problem is downloading files via browser. The download starts and then freezes giving me a network error, this particularly the case with large files (>2gb).

[cookiemonster]

There's no file browser in OP UI so I imagine you're refering to downloading large files from the internet on a client pc's browser in your LAN network. If so, probably nothing to do with OPN but server timeouts, browser memory limitations, etc. i.e. between server and client. Potentially nic driver on one of the interfaces. Realteks used to give the dreaded "watchdog timeout" message.
To verify, you could find a way to make a large transfer via other methods i.e. scp, rsync, etc. across the relevant interfaces.

Many thanks for the prompt reply. Sorry I did not make it clear, yes the problem occurs  when downloading from a Windows PC. I will try your suggestions.

Update:-

Bought a 4 port Intel NIC and installed this in a faster machine, restored the configuration from the original machine and reset the interfaces. The result is much faster, however the first load of a web site is still slow.
