What is Xpress Technology ?
Broadcom’s Xpress Technology is one of the older 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.
It is not recommended to use Xpress in newer network environments (802.11n/ac), and with gaming, as any repackaging of data can introduce some delay.
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 ?
Very Excellent input and sharing.
Keep it up and the God’s of the E-world will bless u.
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?
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. 😄
I assume that this so called «technology» would also slow down if not entirely disconnect those client far from the ap. Network packages come with control data for a reason. Error correction. Less signal strength combined with high interference makes lose packages. Those are sent again until it reaches the client. If the package is big would take more time to send it even though with a considerable chance that they will be lost.
hey, sorry for this comment here but the last one was mine but I ended up posting as anonymous. Can the admin edit that comment to me being the author because I wan’t to be notified of replies.
Feel free to delete this comment then.
Thank you!
I thought UDP would work better because it doesn’t have error control. So UDP packages could be bigger.
But then again, the problem with this kind of workaround is that the processor of the access point is normally very slow. So, if for each package sent it has to rearrange before sending on a high traffic and fast internet connection the ap would simply crash.
I bought a linksys ea6500 a couple of years ago because the cheap adsl / wifi router the service provider «gives» when you sign in couldn’t handle my torrent downloads. As the internet speed is about 30 mbps and bitcomet as default opens a high number of connections at the same time, with different peers. Add that to the fact that I usually let 3 torrent downloads simultaneously (because some are rare and very slow).
The linksys ap was expensive but really improved this problem. Not entirely though It sometimes also crashed. To solve it I had to down a bit the limit of simultaneous connections on bitcomet. Then I changed to uTorrent on the pc and transmission on the nas. Never had that problem again.
