Comcast network speed question
My mom on Comcast Blast internet. 50Mpbs Down and 10Mbps UP
When I do a speed test on my laptop (powerful laptop) is shows 57Mbps Down, 11Mbps UP
On my mom's laptop (older laptop) is only shows half a Download 20Mbps Down, 11Mbps.
I use http://speedtest.comcast.net, and http://www.speakeasy.net/speedtest/. Same results for both.
Xfinity Router Model TC8305C.
Older laptop: Sony VGN-N220E.
Same WPA2 AES encryption.
Why is the speed different? Different WiFi NIC?

Maybe this will explain http://curiosity.discovery.com/question/why-cable-internet-tend-fluctuate
Each laptop's WiFi versions: 802.11b, 802.11g, 802.11n or the lastest 802.11ac.
Each laptop's WiFi adapter drivers.
Which OS, Firewall, AntiVirus...
Unless you have Comcast Business EDI (Ethernet Dedicated Internet) your bandwitdth is shared and speed will vary based on time of day usage, etc.

is it because the older laptop has (802.11b/g) WiFi NIC,
and the newer is 802.11 b/g/n ?
I set the router to B,G,N and WPAWPA2-TKIP/AES security.

Older laptop WiFi NIC: LAN-Express AS IEEE 802.11g PCI-E Adapter
Driver: 2.0.0.75
I tried to update and says it the latest up to date driver.
Is the max for 802.11G 54Mbps but in reality its less? Overhead, etc?

Tira,
Yes. 54 Mbps is burstable if available. There is a technology called dynamic rate scaling. What happens with that is that if the connection is not strong enough, the speed will fluctuate reducing the maximum transmission speed to a lower number so it stays connected.

This is a white (beige) color.
I haven't tried with a patch cord yet to make sure its a WiFi connection. Sorry for the delay.

Please run the Intel wizard from link in my last post.
Otherwise you need to install correct drivers.

No Luck on WiFi NIC drivers. I guess its a hardware limitation. Parth network cable works fine @58Mbps.
Oh well, I will get a USB wireless adapter or a drop a cable there.
Thank you all.
