Moto Surfboard SBG900 and VPN Client = SLOW

My Moto SBG900 gives great service on cable until I start my company's VPN client. Then, my 8 Mbps (download) connection goes to 50kbps!! When I disconnect and reboot the modem/router my speeds come back to normal. Is there a modem setting somewhere that can fix this?

Please see the specicification, also check with you company
IT Admin, to release it to the Max speed or to check the
net work cable, may be too long, also Test the cable with a Data Test meter and conform the data quality. Or change the port from main router.
Otherwise change the whole networking router.

What is the best modem to connect to the internet via VPN?

This is a known issue with that modem and Comcast wont support VPN from residential installations. If you want to change modems that don't have this issue, get a Motorola surfboard. If you want to change settings on the one that you have because of the protocols for assignment of addresses let me know

Motorola Surfboard SBG900 will not connect to Playstation Network

You need to give the PS3 its own IPAddress outside of the firewall. You need to configure the router and the PS3.

I am unable to connect to my VPN, although my wireless connection is excellent

Double check that you are using the proper WEP key and VPN settings. You can also try using a different channel for your wireless. Many of these systems use Channel 6 as the default channel. Change this to channel 10 in the router. If you are forcing 105mbs you will need to change that to automatic to make this change as in forced 105 mode the only broadcast channel to use if 6.

Best to call up the cable company and go thru the phone may just find that they're having trouble in your area...
They can also send a reset signal to your modem too.

Can't connect to AT&T VPN

as you told me that all the ports are open so in that case you can get in touch with your ISP and ask them to enable IPPASSTHROUGH on your office laptop.

I get connected to my work VPN, but i can't sea any servers.

Because when you want to browse free it will happen, so better check with he hotel/fastfood or airport IT admin, he would have blocked it.
Good Luck
