Tweaking mobile wireless performance on Vista

The one thing I have to say is that I am addicted to being connected to the net.  From my smartphone to my laptop I kind of wish that every device had the ability to plug-in to the net.

I any case, I currently have a Verizon USB727 USB wireless modem.  Overall I am very happy with the performance.  But it seems that performance seems to vary a bit from minute to minute and hour to hour.  I have been finding myself disconnecting and reconnecting to the Verizon network, multiple times of the day.  My performance would vary from 50-60Kb all the way to 800-1000Kb.  A big variation if you ask me.

I had to install the following hotfix...

Additionally I setup my USB727 modem to use the NDIS interface.  This allowed me to utilize the OpenDNS DNS servers.

I then renamed the connection to "EDVO" and set the OpenDNS servers

If you want to set the DNS servers on the command line you can use the following syntax

netsh interface ip set dnsserver EVDO static 208.67.222.222
netsh interface ip add dnsserver EVDO 208.67.220.220 index=2

 

My TCP settings

Now my connections are very stable and fast 500Kb-1.3Mb....Yippee!!!

Poor Network Performance on Vista resolved?

I hope everyone has had a good new year.  I just wanted to let everyone know that I have partially resolved my large file copy issue by installing the recently released Vista SP1 RC Refresh.

My file copy woes are not completely over, see picture...I only get about 28 MB/sec performance across the GB interface.

If anyone has any ideas please let me know.  I recently switched to Intel GB NICs in hope it was due to the on board broadcom cards, but it didn't make a difference.  The next thing is to replace my linksys switch.

One other thing, I needed to turn ECN Capability off.
