No, they're completely different things. MIMO refers to the ability to split a single data stream over multiple, adjacent communication channels and requires more than one antenna. MIMO can, in theory, be used to improve both the bandwidth and the directionality of WiFi signals. In practice, implementations available today just seem to increase the ...

Which configuration would be more efficient on a wireless environment with many devices (~40)... In your environment I'd deploy two single-band APs for the following reasons: Coverage would be superior. First, two APs enable placement options for better coverage than one can. Second, a dual-band AP will offer 2.4 GHz and 5 GHz radios, but the 5 GHz ...

this would actually be a better question for electronics.stackexchange. you should choose the 5ghz spectrum A 2.4ghz RF signal, due to lower frequency, will penetrate walls and objects more easily. However, a 5ghz RF spectrum signal has shorter wavelength, and therefor its antenna can be (longer and) better tuned for higher gain within the same space ...

Really there is no best practice; the best you can do is choose the lesser evil. Connect with one subnet, as you describe in your question. If it is connected to one common client subnet, DHCP must kept only on one device Set the default gateway to the ADSL device You must configure all firewall, dst-nat (eg. portmap, service publication), UPnP on ADSL. ...

You need to ensure the following: You need to run NAT (Network address Translation) on Computer A on the WIFI interface - presumably you would use "connection sharing" in Windows. You would treat your WIFI router as an Access Point + Switch - you want to disable DHCP on it as Computer A would be doing the connection sharing. You would also want to ensure ...

Interference will kill your throughput. Period. Therefore, choose the channel without interference. Also, read about the 'hidden node' problem. It will be exacerbated by strong AP signal.

In general you will want to use the quieter band. Its difficult to remove the characteristics of 5g vs 2.4g out the equation - and may send you down the wrong track, but this answer will attempt to do that. There are (at least) 2 aspects here. The more obvious one is this - If there is a signficant amount of other traffic in the band, regardless of how ...

First, what brand are your laptop and phone? Apple products are known to be bandwidth hogs. You could try to change the channel and or frequency of the WiFi. And it is possible that something in that room could be causing interference and distorting the signal.

Okay, I did a bit of research, and I know what's wrong here. Apple does not allow 40 Mhz or "bonded channel" mode in 2.4 Ghz mode in their devices. So even if one's router is capable of 40 Mhz mode in 2.4 Ghz, an Apple device will only use half of that (they do support 40 Mhz in 5 Ghz mode though). What this means is that whatever bandwidth your router is ...

What you are talking about is a Wireless Broadband or a Fixed Wireless and also known as Wireless mesh network . Also it is called a point-to-multipoint network. Wireless Broadband Network A term you may recognize in association with wireless broadband internet service includes wireless network. A wireless network is a single broadband internet ...

Under system preferences, select the Sharing icon and see if you have any of the services there checked, these services allow you to share with others on the network. If nothing is checked (On) then you should be fine in the sense that no one can easily browse files or folders. If these services are checked, you will need to either uncheck them and stop ...

Enable MultiAP Isolation option looks similar to Client Isolation. The former option is available in D-Link 2750.

Assuming you mean 1 MB/s, this seems about right. A realistic system like this probably has a hardware maximum of about 54Mbps and a usable link bandwidth of about 20Mbps given typical parameters of distance, interference, and so on.. There are 8 bits in a byte, all data has to be sent twice (once to the AP and once from the AP), data has to be acknowledged, ...

There are a few things that are working against you here: The router is old and doesn't support 802.11n (assuming your laptops are capable of "n" that could make a big difference) Distance between router and laptop Degradation of signal due to physical obstacles (i.e. the floor) Degradation of signal due to intereference from other wireless devices ...

According to the tests I realized this week with wired network between a RaspiberryPi (with Raspicam) and my laptop, Gstreamer has better performance and less latency than VLC. I had around 1sec delay with VLC, and it was not constant, sometimes the video slows down and sometimes it accelerates. With Gstreamer I can stream a HD video (1280x720 @ 60Hz) with ...

I have some experience with Sierra Wireless MC7710 (connecting it to Mikrotik Router). It not have physical UART, but driver give to OS 5 serial interfaces in Linux . But Windows 8.x use for Qualicomm modems special native mode QMI (Qualcomm MSM Interface), where all configuration done over driver API (or maybe over IP) ...

FC21 on Yoga 3 WIFI works, see this: http://niteshnarayanlal.blogspot.hk/2014/11/setting-up-fedora-to-work-with-broadcom.html Also, power saving on my Yoga3 is wonderful with FC21, see this: https://plus.google.com/108110137184055365183/posts/CmsjAfNMw6p

I just dealt with this for the past couple of days, with the Yoga 3 Pro, with a fresh install of Fedora 21. I'm assuming you're using your phone to tether the machine to the internet and ran "yum update" after installing. Like other people/sites have said, installing kmod-wl from the terminal does work as root. If your install is like mine, the problem is an ...

I configured the local wifi router to provide a wireless network with a separate SSID to make sure that devices connect to the correct router. Both local and main wifi router were configured to provide IP address, gateway and DNS servers through DHCP. An old notebook was connected to the "Internet" port of the local router. The LAN connection of the ...

-Log into your old router -Configure your old router to be a unique SSID -Disable DHCP of the old router -Connect Port 1 of your old router into port 1 of your new router You do not want to connect the "Internet" Port of your old router to the LAN port of the new router. This can cause all sorts of NAT & port forwarding issues. Also your old ...

It's possible that the device is flooding the network with wireless signals. I once enabled sound broadcasting in my home network over wifi and that made wifi network almost unusable. This problem didn't exits over ethernet because of the higher bandwidth. Use a packet capture software like wireshark to see if this is the case. Actually on windows you can ...
