No.  Workgroup Bridge only works with one (1) radio at the same time.

15. Since the Linksys LAPAC1750 supports dual images, can I swap the firmware between two flashes?  

No.

16. How many MAC Addresses does the Linksys LAPAC1750 have?  

The Linksys LAPAC1750 has three (3) legal global MAC Addresses, one (1) is LAN MAC Address and the other two (2) are Wi-Fi radio interface MAC Addresses for 2.4 GHz and 5 GHz.  The multiple SSID and Workgroup Bridge interface MAC Addresses are temporary and they are calculated base on Wi-Fi radio interface MAC Address.

17. How does the bandwidth usage mechanism of the upstream and downstream bandwidth rate limit work?  

All wireless clients associated to an SSID will share the bandwidth, the SSID have been configured with Rate Limit.

18. Does the Linksys LAPAC1750 support 802.11r fast roaming? 

No.

19. What is the function of the untagged VLAN ID?  When can I use this option?  

Frames belonging to the untagged VLAN ID do not carry VLAN tags when sent over the trunk.  Conversely, if an untagged frame is received on a trunk port, the frame is associated with the native VLAN configured on that port.  The untagged VLAN ID is similar the proprietary term native VLAN of Cisco switch.

20. What is the function of SSID wireless client limit?  How does the Linksys LAPAC1750 handle the wireless client which exceeds limited quantity?  

You can set a max of wireless clients to connect to an SSID.  When the limit has been reached, the wireless client will not be able to associate to the SSID it will fail to connect.

21. Does the Linksys LAPAC1750 support file integrity check for firmware upgrade file?

TROUBLESHOOTING

1. How do I avoid interference?  

Using multiple access points on the same channel and in close proximity to one another will generate interference.  When employing multiple access points, make sure to operate each one on a different channel or frequency.

2. How do I reset the access point?  

Press the Reset button on the back of the access point for about 15 seconds.  This resets the unit to its default settings.

3. How do I resolve issues with signal loss?  

There is no way to know the exact range of your wireless network without testing.  Every obstacle placed between an access point and wireless computer will create signal loss.  Leaded glass, metal, concrete floors, water, and walls will inhibit the signal and reduce range.  Start with your access point and your wireless computer in the same room and move it away in small increments to determine the maximum range in your environment.  You can also try using different channels, as this may eliminate interference affecting only one channel.  Also, you can go the access point’s web-based setup page, click Wireless > Advanced Wireless, and make sure the output power is set to 100%.

4. I have excellent signal strength, but I cannot see my network.  What should I do?   

Wireless security such as WEP or WPA is probably enabled on the access point, but not on your wireless adapter or vice versa.  Verify that the same wireless security settings are being used on all devices in your wireless network. 

5. What should I do when there are no LEDs lit on the wireless access point?  

If the wireless access point has no power and you use a PoE switch to provide power to the wireless access point:
  • Make sure that the Ethernet cable between the wireless access point and the PoE switch is connected correctly at both ends.
  • Make sure that the power cord of the PoE switch is plugged into a working power outlet or power strip.
  • Make sure that the PoE switch is functioning normally.
