What is Xpress Technology ?

Broadcom's Xpress Technology is one of the popular performance-enhancing WiFi technologies, designed to improve wireless network efficiency and boost throughput. It is more efficient in mixed environments, and it can work with 802.11a/b/g networks.

When Xpress is turned on, aggregate throughput (the sum of the individual throughput speeds of each client on the network) can improve by up to 27% in 802.11g-only networks, and up to 75% in mixed networks comprised of 802.11g and 802.11b standard equipment.

The technology achieves higher throughput by by re-packaging data, reducing the number of overhead control packets, so that more useful data can be sent during a given amount of time.

Very USEFUL. THANK YOU!!!!!!!!!

Do the network adapters that connect to the AP need to support this technology or is it compatible with most or all recent network adapters?
My wifi router supports it but my notebook wifi card doesn't have an adjustment for it

atheros 5200 series dosent support it, and i dont know if there is a "software solution" for this, i have the lastest driver and firmware, but it still not working! any help ?

OK. Do you mean enhancing throughput of "Wan" or "Lan'?

If your ISP provides Uppload speed of 1.5 Mbps and your ADSL Wireless Router "WAN throughput" upstream is 1 Mbps. Does this help in this case? will it add mre Mbps to the upstream?

Does it also Speed up WAN throughput Speed of downstream (24Mbps) and upstream (1 Mbps) ?

It only refers to LAN, unless you connect to your ISP via WIFI :D

if it repackages data inside the router, would this only effect tcp protocol? What about UDP? Basically, I'm just wondering if this will help or hinder my gaming,in which some packets may be sent tcp.

It only affects local WiFi traffic, not the Internet side of a router, so it will have very small effect. However, I wouldn't use it in environments with few clients, or games where ping/latency is more important than high throughput. Gaming often performs better with all types of packet-aggregation turned off.

If you have an Wi-Fi router which support "n" or the much modern in our days "ac" standard - you would like to disable permanently so called "XPress" technology and never activate it. It was an old improvement trick for "b" and "g" and it was replaced by much more efficient and fast protocols like the one by default in "n" and "ac".

Test shows that activating "XPress said" makes download and upload speeds lower and also makes live streems like movies or radio/music utilizing UDP protocol to not work. For example - you will be no longer able to stream movies - instead you will need to download them and just then playback will work. 😄
