5GHz performance affected by client on 2.4GHz band? #1138

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
======================================
1. I have both bands on RT-N56U enabled.
2. Laptop1 can connect to '5GHz' band with 300 Mbps connection speed. The VOIP 
on this laptop works good, the signal strength BEST. All is ok. 
3. I recently bought a Lenovo laptop2, which unfortunately can't connect more 
than 72Mbps speed (and that) to 2.4GHz band.
4. Once this laptop2 connects to the network -- the PROBLEM starts! --
5. The laptop1 now connects ONLY with 150Mbps connection speed, the signal 
strength is 1 bar less (same position), and voip quality deteriorates. Until I 
reboot the router and NOT bring laptop2 on the network - this situation 
continues. 
6. No samba, no upnp enabled.

What is the expected output? What do you see instead?
=====================================================
I observed that one 2.4 GHz client, deteriorates the 5GHz band performance. Not 
sure why the laptop2 (on 2.4 GHz) band cause the issue with laptop1's 
connection speed (on 5GHz). 

What version of the product are you using? On what operating system?
RT-N56U_3.4.3.7-075_dlna.zip

Please describe the problem as detailed as it's possible.
=========================================================
Is it possible to get the "Channel Bandwidth" to be exclusively 40 for 5GHz. Is 
there any other setting at Router level which can somehow absorb this different 
laptops' needs, and not degrade in the performance? What can I offer to help 
debug this issue? 

If you have connection problem, then syslog file is required. (please do
attach it as a file)
Note that if there will be a poor problem description the issue status will
be changed to 'Invalid'!

Try disabling "Greenfield".

Tried with mixed mode on both bands. No difference.
