QUESTION POSED ON: 20 June 2007
My customer is a small business experiencing problems connecting to their file server through a VPN.
The customer connects easily, but the connection often slows considerably when downloading or uploading (saving) files, when inserting files into an email, etc. Often (20-25 times a day) they have to disconnect and reconnect to the VPN again to make it work faster. The problem is worse around Noon.
They have an ADSL 4096/512 connection that works fine ─ also around Noon ─ surfing the Internet, downloading from ftp, etc.
They are on a LAN (not wireless), but there is a Linksys router connected to the network.
Turning off the firewall doesn't affect the problem.
I experience few or no problems connecting to their VPN from my office or home. I have a 100/10mb connection; not ADSL, but a private network that I share with other people. I use a wireless connection at home, and it seems like the VPN is much more stable.
The strange part is that the VPN is the only network-related element that doesn't work at that office. Any ideas why it is so unstable?
