Question
Solution
l
Check whether interference of same devices exists. To be
specific, check whether wireless devices exist around. If yes,
power off the devices and check whether the interference is
reduced. Alternatively, you can mask the devices that gener
ate interference or adjust their locations.
l
Check whether interference of other devices exists. To be
specific, check whether interference sources that greatly
affect the working of the device, such as microwave oven
or other high-power (2.4 GHz) devices, exist around. If yes,
power off the devices and check whether the interference is
reduced.
l
Check whether incompatibility problems occur between the
STA and AP. The STA may not comply with the 802.11 proto
col specifications, which leads to the connection failure.
Why is the bandwidth
not high after the
connection of wireless
network is established?
Usually, this problem is caused by environment interference,
aging of the device, or reduced TX power. You can do as follows
to solve this problem:
l
Check the wireless channel. To be specific, choose another
wireless channel to see whether the rate is greatly increased.
l
Check wireless interference. To be specific, check whether
wireless devices exist around. If yes, power off the devices
and check whether the interference is reduced. Alternatively,
you can mask the devices that generate interference or adjust
their locations.
l
Check signal strength. To be specific, check the signal stre
ngth between the STA and AP. If the signal strength is low,
the antenna may be loosened or the output power is reduced
due to aging of the device.
l
Check the NIC. If the the NIC power is low, you can test the
bandwidth near the AP.
