I have a WIFI hub that gets around 30mb down load and 9mb upload. We make alot of use of internet based TV and at night there are around 4 different TV set boxes running. These are all hard wired via means of a powerlink system however can run on WiFi.
It seems we get alot of buffering issues/lag so I've wondered wether a new more powerful modem/router that can run a vpn would be a solution to better internet experiences.....
If this would be the case what would be a good purchase? Currently been looking at a Linksys WRT32X
Just watching BBC iPlayer in a browser window on a laptop seems to require an average of 7 Mbps right now.
SKY GO is occasionally maxing-out my 32 Mbps connection just using a laptop.
With your speed of 30, that may just be enough for 4 relatively low resolution streams so some buffering is not unexpected.
As for using a VPN, as your connection then goes through a third party, I would not expect anything but a slightly slower speed.
Where a router can be a VPN client, that encrypts everything from the router to the VPN server of your choice. Is this more secure than using VPN clients on each of your devices - no.
With the routere as the VPN client, your WiFi network is not part of the encrypted tunnel, which is the most insecure part of your network.
As I said before, if the router is the VPN client, then the encrypted tunnel runs from there to the VPN server, leaving the WiFi unprotected. To be honest I don't think that is really giving you much extra protection over & above what the operating system/security suite/applications may offer.
Your router, your security, your money, your choice. I just wanted to make sure that you are aware of the disadvantages of using a router as a VPN client.
