You must consider your lowest common denominator and adjust your power equally between your client and AP for optimal design.īut did you know when you select different UNII channels in the 5 GHz band you are also changing the TX power of your AP on a Cisco WLC? When selecting power on a cisco ap in the WLC you are presented with the power levels 1,2,3,4,5 etc. NOTE: You may need to uncheck the box next to Use default value to make any changes. Just to clarify in regards to the Power Levels a TX Power of 1 is the highest transmit power as George has indicated below this message so 5 would be a lower setting. One of the MOST important design factors is selecting the proper radio TX power when designing any wireless network. In the Property: box, click Transmit Power and move the slider to Highest. Depending on the channel you select in 802.11A ALSO changes the TX power. Lastly keep in mind that it could also be a client side power issue, since the communication to the AP has to be a two-way communication which means if your client has a maximum transmit power of say 25mw or 14dbm, then having the AP push out 50mw or 17dbm of signal is useless since in many cases the AP can reach the client device but the client device won't be able to talk back.Īlso keep in mind. You could try setting the minimum to say 12.5 dbm which is like power level 1 or 3 depending on the radio, band, channel, modulation, etc. Note: Do not change the transmit power for an APs 2.4GHz radio.
INCREASE WIFI TRANSMIT POWER ALFA CODE
The other option you have in the newer code is the set a minimum and maximum that the RRM system will allow, here you see they are set at -100 & 100 respectively. If you find that your wireless clients have connectivity issues (i.e., videos buffering, slow browsing) after increasing the transmit power, revert the radio to Auto transmit power. According to measurements via laptop wifi card and status info.
INCREASE WIFI TRANSMIT POWER ALFA HOW TO
You may need to change this to -65dbm but be aware that this could cause more co-channel interference depending on where the next ap on the same channel is, this setting is also global. 2565 I will show you how to increase tx power for Alfa AWUS036H and other Alfa WiFi adapters. wlc-2 (x.x.x.x)ĭefault now is -70dbm which means that the ap's will turn down their power until their neighbors hear them at a -70 signal. See the commands below and some sample output. This could be tweaked some using the Tx-power-threshold settting. I would first check the transmit power threshold you have configured on the controllers, using the 2 commands shown here, there is a good possibility that because of the distance between the AP (especially with out knowing if there is anything between the AP's) that they are seeing each other so strong that they have to turn the power way down as a result. So based on that the fact that you said Power Level 8 gives you a stronger signal is suspicious to say the least.
Your description of the problem makes no sense especially considering that a power level of 8 is lower than power level 2.
