5Ghz connectivity.

[muhsi_2015]

Hi,

client always connecting to 2.4Ghz instead of 5 Ghz .

Does it mean the network not designed for 5Ghz ?

Here is the scanning result of an apple device

TEst "AC:AA:77:77:11:22" "-85" "36" "1:45:12 PM"
"AC:AA:77:77:11:22" "-73" "1" "1:45:12 PM"
TEst "AC:AA:77:77:11:22" "-85" "36" "1:45:18 PM"
"AC:AA:77:77:11:22" "-73" "1" "1:45:18 PM"
TEst "AC:AA:77:77:11:22" "-85" "36" "1:45:21 PM"
"AC:AA:77:77:11:22" "-73" "1" "1:45:21 PM"
TEst "AC:AA:77:77:11:22" "-85" "36" "1:45:24 PM"
"AC:AA:77:77:11:22" "-73" "1" "1:45:24 PM"

thanks

Channel 36 is 802.11a.

Output above shows the wireless client is compare the RSSI values of 802.11b (-73 dBm) vs RSSI values of 802.11a (-85 dBm) and correctly chooses the radio with the best RSSI value found.

Hi

In the above case client choose 2.4 Ghz , correct ?  . since is is getting higher rssi -73 than -85 .

So my question does it mean the  rf not designed properly for 5 GHZ ?

Thanks

No, it could mean a lot of things.  

Walk closer to the AP and see if the wireless client joins 802.11a if the signal is stronger.

Hi,

Yes when it is closer to the ap ,its joins 802.11a

Thanks

This is, therefore, NOT a wireless issue.  This is plainly a deployment &/or budgetary issue.

Do a site survey and put more APs.
