WLAN deployment on old University Dormitory
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
I'm trying to improve the connectivity of students on an old university dormitory and I would like some help in the problems I'm receiving.
This is a diagram of the floor:
Two APs are powered from a PoE switch and the remaining two are powered from a PoE injector connected to first APs (This I'm planning to change)
AP configuration:
I measured the signal in the room and every room except two are between -55 and -65. The remaing two are in -65 and -70.
Here is a snapshot of cliente conectivity now:
On the controller I limit the RSSI to -80 for 2GHz and -75dBm for 5GHz.
I limiteed the download/upload speed to 15M/15M
I activated band steering.
The students are telling me that randomly experience disconnections and low speeds, what I need to do to improve WLAN stability?
Regards,
Some more hopefully helpful bits of advice:
One is to fix your 2.4G channels (use only non overlapping 1,6,11) at 20Mhz and do NOT allow them to go to 40Mhz. The only time you should consider anything other than 20Mhz is if you have 1 AP in a cabin in the woods... Letting the AP decide (Auto) can be particularly problematic.
Two is to manually engineer your frequencies, particularly for 2.4. If you think of your current APs being in the 4 quadrants of a graph, then starting with quadrant 1 and going counter-clockwise I would fix them at 1,6,1,11 (subject to any other local AP interference on those channels). For 5.8ghz, not all channels are created equal in all regions. Have a look at the maximum permissible power output of your available channels for your region, select accordingly and be mindful of potential overlaps if you enable channel bonding (ie >20Mhz).
Here's an excerpt from the Wikipedia page for "List of WLAN channels" which I advise you to review, pay particular attention to the notes and country specifics at the bottom of the table.
