NWA-3160 Series User’s Guide

Check the settings for QoS. If it is disabled, you might consider activating it. If 

it is enabled, you might consider raising or lowering the priority for some 

applications.

I cannot access the NWA or ping any computer from the WLAN.

• Make sure the wireless LAN is enabled on the NWA
• Make sure the wireless adapter on the wireless station is working properly.
• Make sure the wireless adapter (installed on your computer) is IEEE 802.11 

compatible and supports the same wireless standard as the NWA.

• Make sure your computer (with a wireless adapter installed) is within the 

transmission range of the NWA.

• Check that both the NWA and your wireless station are using the same wireless 

and wireless security settings.

• Make sure traffic between the WLAN and the LAN is not blocked by the firewall 

on the NWA.

• Make sure you allow the NWA to be remotely accessed through the WLAN 

interface. Check your remote management settings. 

Some clients cannot connect to or keep on getting disconnected from the NWA’s 
wireless network.

• Check if you have Load Balancing enabled. Wireless load balancing is the 

process whereby you limit the number of connections allowed on an wireless 

access point (AP) or you limit the amount of wireless traffic transmitted and 

received on it.

• If you enable this function, you should ensure that there are multiple APs within 

the broadcast radius that can accept any rejected or kicked wireless clients; 

otherwise, a wireless client attempting to connect to an overloaded NWA will be 

kicked continuously and never be allowed to connect.
