Download errors

[markcuk]

 

Hi All

 

I have a really annoying problem which I just cant get to the bottom off.

 

We have a London office and they are connected to BT EFM 10mb line through a Netgear FVS318G Firewall connected to the BT equipment

 

 

Anyway we have get random intermittent download problems like the screen shots attached. I have tried the following

 

1. We had this using 2 different ISP (We had temporary connection using Urbanwimax when we moved in) I thought maybe the wifi was dropping packets but now we are on fixed line we are seeing the same problem

 

2. We have taken everything off the network added things back same problem

 

3. I have changed the MTU setting down from 1500

 

4. I have a PC directly attached to the firewall to bypass the internal network and I still get the problem

 

5. I have tried all suggestion from mozilla and wetransfer and different browsers etc

 

This happens on both Mac's and PC's and usual when downloading from wetransfer.com that uses amazon s3 servers, I have seen it fail also on other random websites but we use Wetransfer the most and that's where we see the error most.

 

The netgear also serves as a VPN connection to Manchester for the IP Phones

 

I am thinking we should try a replacement firewall but I am not sure it will fix the problem any ideas?

 

Thanks

Have you got any IDS/IPS setup on the firewall

[Domino]

Could be a speed/duplex mismatch between the firewall and the BT equipment?

[RabbieBurns]

can you connect directly to the BT equipment to rule out the Netgear?

Prolly not much help but are there any firmware or upgrades for the netgear. Assuming as mentioned above you can connect directly to the bt equipment to rule out the netgear ??

[markcuk]

Yes I have looked and there are updates to the firmware. Anyone know if it will keep the settings? if I do an update

 

Difficult when I'm in Manchester!! and I have inherited all this

No option to save a backup of the config or would that mean you would need to go through and manually make a note or screen grab the settings to re configure them ?

I'd agree with this. If you take the firewall out of the equation and the issue stops then it's your firewall doing something. Have you tried looking in the firewall logs too?
