The transmit rate is too low for the PHY mode. It should be around 54. Either you have interference or something is wrong internally, such as a loose antenna connector.
Before I messed with the antenna, the Intenet connection went back to normal. From the information about the wireless signal I posted earlier, the only difference is that Channel is 11 instead of 1.
- What does channel mean or measures?
- What could be a reason for the channel number to change?
