How many concurrent users can a single Wi-Fi AP handle?

How many users can a single Wi-Fi access point handle at one time? For example, can a single AP handle 100 concurrent users?

Is it possible to have multiple repeaters in a network with just 1 uniform SSID?

I'm currently setting up a network with 1 access point. Since WiFi range is not very far, I'd like to extend the range by using repeaters. I did several setups in the past but they always had another SSID. So I had an SSID for my repeater which computers and devices could connect to, and the repeater connects to the main access point.

Is it possible to have a router with a name 'linksys' and 3 repeaters connected to it? Would it be possible to have all repeaters to have the name 'linksys' so only 1 SSID would appear in the networks detected? Is there any other option to this if it's impossible to do with repeaters?

Connect to Wi-Fi access point with specific MAC address

I can see several (5+) Wi-Fi access points with the same SSID, but different MAC addresses (using InSSIDer). However, my Windows 7 laptop always keeps connecting to one of the APs, and I suspect it's not the best one.

How can I choose to connect to a Wi-Fi access point with a different MAC address? Is there a custom connection manager that allows specifying the MAC address of the preferred AP?

How to find the IP address of an access point that I'm connected to?

I'm connected to an open network, I can see the BSSID and the SSID but I don't think DHCP is enabled because I don't get any IP. so is there a way to find out what is it's IP remotely ? and thanks

Considerations about using multiple Wireless Access Points with the same channel and SSID

I have looked all over, and everything I have read says, if you run a multi-WAP setup with the same SSID you should stagger the channels.

Can anyone tell me in more detail why this is needed besides "to avoid interference"?

• What does the client do when both APs are on the same channel?
• What kind of errors can I expect?

Difference between wifi router and access point?

I see both terms used, and I was wondering what the difference is between a wifi router, and a wifi access point. Does the latter only create a LAN, with no way to connect the wifi box with a second network?

Thank you.

Is it better to use a crowded 2.4GHz Wi-Fi channel 1, 6, 11 or "unused" 3, 4, 8, or 9?

I understand that 2.4GHz Wi-Fi channels overlap, and that the most popular non-overlapping set of channels in the US is 1, 6, and 11. Generally, my signal strength on channels 1, 6, and 11 are much stronger than my neighbors' on the same channel. However, these channels usually have 4 or 5 APs already using them. In this scenario, is it better to use 3, 4, 8, or 9? Or is it better to use the crowded channels 1, 6, and 11?

As a secondary question, does it even matter that my signal strength is much higher than theirs?

Why use wifi channels other than 1, 6 or 11?

Which 5Ghz channel to use?

My "better" router has 5GHz channels - 36,40,44,48,149,153,157,161

My not so much better router has 5GHz channels

• 36,40,44,48,52,56,60,64,100,104,108,112,116,132,136,149,153,157,161

I am confused as to why the least expensive one has more channels compared to the "better" one. And also curious with which channel is best to use and what the difference is if I pick a lower channel compared to a higher numbered channel.

Getting IP Address of Access Point

recently I turned my Router to a wireless access point for my home network. Unfortunately, I forgot to note down the AP's IP Address and Subnet.

How do I reliably get the IP of my AP?

Thank's in advance.

EDIT: OS is Vista XP, but I have xubuntu dual booted.

Ok so the configuration is as follow: PCs => (wireless) Belkin Router (AP) -> (wired, bridged) 2Wire Gateway Modem

I want to be able to get the IP Address of the AP, ie. the Belkin Router

How to setup Access Point (WiFi hotspot) on Debian

I'm trying to setup an AP got stuck. I'm using an Odroid U3 and the WiFi adapter is the Module 3 from Hardkernel. I'm also using a Debian Jessie.

Not, I've got it to almost work: the Odroid has access to the internet and other devices (my phone and my tablet) can see the network, however when I try to connect to the network, I get the message: Unable to join the network "myNetwork".

My hosts file is as follow:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

auto lo br0
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual

# Bridge setup

# for dhcp address
#iface br0 inet dhcp
# bridge_ports eth0 wlan0

# for static ip

bridge_ports eth0 wlan0
# adapt with your network settings

gateway 192.168.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
fns-search localdomain

my hostapd.conf file is:

    interface=wlan0

wpa_pairwise=CCMP
rsn_pairwise=CCMP

After some research, I've found an answer on SO (unfortunately lost the link) where suggests that the problem might be related to dynamic ip addresses for the devices connecting to the Odroid, but I'm not sure that's case. Any suggestions?

Many thanks

External Antenna on wireless router

I have a "Linksys WRVS4400N wireless N router" that i'm thinking about relocating out of the high traffic area of my home. When I move it with the other networking equipment in the basement, my signal strength drops to inadequate levels in the rooms that I would like to use wireless devices.

I'm thinking about running wires in the walls to an external antenna (like these) mounted high on a wall in the main living area. From my reading, it seems that an external antenna might not work well with a N router, so i'm entertaining the option of switching to a different A/B/G/I access point if need be.

Any advice on designing a working setup to relocate external antennas to a different floor than the AP?

Edit: It seems that the WRVS4400N can operate in B/G mode which is what i'll probably do as its span port and VPN endpoint are nice features. Any ideas if attaching an external antenna to this unit running in B/G mode will work?

Should I expect problems with signal strength to the external antenna if I am to run 20 feet of wiring/cable to the antenna? Is there a certain antenna type/make that I should be using or avoiding?

Wifi is slower than Ethernet cable connection?

I configured my new router and noticed that WiFi connection is way slower than Ethernet connection.

Ethernet connection giving a download speed of ~60Mbps and upload speed of ~30Mbps while the Wifi only giving download speed of ~20Mbps and upload speed of ~15Mbps.

This is a new router with 802.11n and it says it support 300Mbps.

Here are the Wifi settings of the router,is there anything I can change to get higher speed :

Difference between indoor and outdoor WiFi Access Points

Does anyone know if there is an operational difference between what is classified as an 'indoor' wifi access point and an 'outdoor' wifi access point. I'm speaking specifically to its operation rather than things like whether its enclosure is weather proof or not. And I'm also referring to the access point itself as opposed to the antenna used.

How does a WiFi client choose an AP if two have the same SSID?

When a WiFi client wants to connect to a hotspot with a certain SSID and there are two access points with that SSID, what determines which one it connects to? If it previously connected to only one of them, does it somehow "recognise" that one and prefer it? Or is it only a matter of which one provides a stronger signal? The hotspot is unsecured, if that makes a difference.

Also, once connected to one AP, does it try to stay on that one as long as possible or does it constantly look for a stronger signal and switch as soon as it finds a slightly stronger one?

Set up wireless networking solution for small office (<30 people)?

I have one wireless router (Linksys E2500) that's currently providing wifi for ~18 people on laptops, plus some of their devices (e.g. tablets). The network has gotten slow lately, and we're pretty sure it's due to wireless congestion as plugging in directly to the router eliminates all latency issues.

We have a few options as we see it:

• Upgrade the router to something more robust/industrial
• Get a separate wireless access point, plug it into the router, and instruct some of the people to connect directly to that
• Wire the office with ethernet cable along the walls (this is less desirable, especially since we aren't sure how much longer we're going to be in this space)

What would you recommend?

One thing we already tried is disabling the 2.4ghz spectrum, so only 5ghz remained, but then our Windows users were unable to see the network's SSID.

EDIT: So what we ended up doing was getting a new, beefier router (the E4200) and plugging the internet connection directly into that. Then we plugged the older router (the E2500) into one of the ports on the E4200, changed the gateway, and put it up with a different SSID. Now half the people in our office connect to the old one, and half connect to the new one, and our connection issues are resolved.. for now.
