Speed Problems Please help?

Cry Havok

Which of the 1.2.3 versions, given that it's not released that's potentially very important. Which Intel Pro cards - they do a range of them.

Check the speed on the LAN interface. If it is set to 100 half duplex, something is not giving you autosense on the wan side.

I was wondering about a speed/duplex issue, but I would think that would kill the ACKs upstream which would impact downloads, no?

Hi,

The NIC's are Intel Pro/1000 MT PCI Desktop Adapters

Thanks

danswartz

also, his upload is 20kb/sec. even speed/duplex issues would not slow to that kind of crawl, i wouldn't think.

Cry Havok

There's a whole host of things to check. It could be a problem with the network cable, the switch, the port in the switch…

danswartz

these are all hard to believe though - layer 1&2 issues are not going to bork traffic in only one direction! if nothing else, 7mb of downloads is going to be a lot more than 20kb of uploads just for the ACKs.

Cry Havok

They can certainly be a contributary factor - acks are pretty small packets and if the probability of the problem occuring is in relation to the packet size then small packets will be more likely to get through than large packets. I've seen too many strange problems to assume that something improbable can't happen.

Hi,

But the exact same cables and the exact same modem configured to be an ADSL router and no Pfsense box gives me 7 mb down and 1mb up! I've just replaced the cards for brand new out the box ones and still have the same issue!

Any other thought? Could it be a problem with my ISP?

Thanks

Cry Havok

It could be many things, that's the difficulty in diagnosing these types of problems. I'd suggest you try:

1.2.2 (the stable release)
2.0 (the alpha release)

and see if either of them solve your problem. If they do it points to a possible problem with that underlying version of FreeBSD and your particular motherboard and network card combination.

danswartz

Yeah, if so, it might be necessary to get a network trace or something. That does sound weird.

Hi,

Okay I've just rebuilt my pfsense box with ver 1.2.2 and exact same problem. Download speed 6953 Kbps Up speed 12 Kbps!

Covert my Netgear DG834 back to ADSL Router and speed is 7128 Kbps Down and 912 Kbps Up!

I've tried different speed test sites also! same speeds!

Anyone got any other thoughts?

Cry Havok

And now try 2.0.

Supermule

And with the same cables and network cards???

Hi,

yes the same cables switch and network cards! I'll try 2.0 shortly and let you know how i get on.

Thanks

Hi guys,

Well I've managed to sort the problem! it was the MTU! set it to 1400 and it works like a dream now.

Thanks
