I will appreciate if someone can help me with this:
I have problems with my business wifi network. I have one access spot Engenius EAP300 and three access spots Engenius EOC2611P, everything is connected directly to the router D-link DSL-2760U. The network is very weak, and after a few users it collapses all the time. How do u think i can make it stronger? Do u think if I will put password it will help? maybe the router is not strong enough?

Thanks

It depends on your router. If it will show you the dhcp mappings you should be able to see what IP is mapped to which mac address. You can look at the AP and it will have a sticker in most cases telling you the mac address. You can also look at the arp table in the router to try to get those mappings. If all else fails get a ping scanner and ping every ip in your lan subnet. You can then use the ARP -a command to figure out which mac is assigned to which IP.

How far apart are the access points and what channels are they on? How much space are you trying to cover. What is the internet speed when directly connected to the ISP without the WiFi? You defiantly must have password encryption.

The channels are 1, 6, and 11. i have one access point in each floor. anyway all of them connected with ethernet cable to the router. The speed is 10 Mb.
 
The method you are using should increase the total number of users that can use wireless on your network. It is the standard design used in commercial installations. Each radio/ap should be easily able to run 10 users depending what they are doing. The router itself since it thinks all these users are wired should be able to connect to well over 100.

It depends what you mean collapses. If you do not have enough bandwidth to your ISP too many user could use it all up. If you mean the ADSL line gets some kind of error then you need to contact the ISP since it should not actually fail.

You could easily use up a 10Mb internet connection with multiple users in a business, depending on what they are doing. But I would not interpret slow internet as a "network collapse." Can you be more specific about the symptoms? Does the network lose internet access or do you lose access to your server or other computers?

WiFi encryption is always preferred for a business network, though it will only make a difference to your current situation if it excludes someone who is already illicitly tapping into the WiFi.

Thanks for the answers. by saying collapses i mean that no more people can get internet access. usually there are about 10-15 users, so i dont see any reason for that to happen. Do u recommend to set a static IP for the access points? or let it get one automatically?. The business is pretty isolated so i'm not sure password will actually help.

Static or dynamic IPs will not make any difference. Nor should will password protection hinder your network performance. As a non-professional in computers, it sounds to me like you need greater than 10 Mb internet speed for 10 to 15 users.

Thanks. I'm trying to connect to the access point but the IP address has changed. i saw in the instruction that i must put the same Ip address in the TCP/IP in the computer. is there any way to find out the IP address? I tried to restore to default setting but it doesnt work either.
