WiFi speeds over Barnacle WiFi Hotspot

This works for Vista and Windows 7.

The legendary tool, DrTCP, which is used by everybody to change the MTU in Windows 2000 and XP, doesn't work under Windows Vista. Fortunately, Microsoft now allows us to adjust the MTU using the "netsh" command. As other commands in Windows Vista, you run "netsh" using the command window, in Administrative mode.

To see what interfaces you have on your computer, type
netsh interface ipv4 show subinterfaces​
To change the MTU, type
netsh interface ipv4 set subinterface "Local Area Connection" mtu=nnnn store=persistent

where Local Area Connection is the name of the network connection on your computer, from the list obtained above. nnnn is the desired value for MTU.

Reboot after making the change.

Thanks for the link. That app looks better than Barnacle, and even though I haven't tried it yet, probably works as good too. I'll try both tomorrow and post the results.

EDIT: Yup, Wireless Tether worked "out of the box" without any settings being changed on my netbook (Barnacle, as you all mentioned, did require MTU modification), and I got great speeds again. This time 6.26Mb/s down, 1.26Mb/s up. I'll be keeping WT and uninstalling Barnacle. Thanks for the great suggestion!

THIS WORKED FOR WINDOWS VISTA AND 7
NOTE: YOU HAVE TO RUN NETSH AS ADMINISTRATOR.







So I decided to actually try out Barnacle today, as I've had it installed for a couple days now. Set my options, started it, and connected with an older Acer laptop that a co-worker had at the office. Here are the speeds I got from the local San Diego, CA speedtest.net server...

5.13Mb down
1.37Mb up

Wow...that's phenominal for a mobile device!

I dont have an unlimited data plan,so can I download Wireless Tether and then connect to it from my phone to save me using my data usage up?

Thanks

I pm'd you the answer to this already when you asked me originally. NO, this is the complete opposite of what you want to do if you don't have unlimited data. Doing a wireless tether will turn your phone into a router and you can use a computer anywhere you want.

What you want is to connect to an existing wireless router. EXAMPLE: a network in your house. Anyone with a smart phone has an existing wifi option to connect to a wireless network.

Please do not use anytype of tethering option b/c you will most likely have to forclose on your house when you get your first bill from tmobile.

Get an unlimited plan. Otherwise, don't tether to any PC/Laptop without knowing how much data you've transmitted and how much your "cap" is. Going over will be quite costly.
