When a low level network device discards incoming data packets usually can also notify that fact to data transmitter in order to slow down the transmission speed (see also network congestion). In the second case discarded data packets can be resent by transmitter and received again. Manually changing the encryption method may affect Wi-Fi performance.Limiting the speed of data sent by a data originator (a client computer or a server computer) is much more efficient than limiting the speed in an intermediate network device between client and server because while in the first case usually no network packets are lost, in the second case network packets can be lost / discarded whenever ingoing data speed overcomes the bandwidth limit or the capacity of device and data packets cannot be temporarily stored in a buffer queue (because it is full or it does not exist) the usage of such a buffer queue is to absorb the peaks of incoming data for very short time lapse. Ensure that WPA/WPA2 PSK hybrid is the default Wi-Fi security encryption mode.(On the web-based management page, click More Functions > Wi-Fi Settings > Advanced Wi-Fi Settings and change the settings in 2.4GHz Wi-Fi or 5GHz Wi-Fi.). If the interference source is strong, modify the Bandwidth to 20 MHz and set the 11n guard interval to Long.Change the channel settings in 2.4GHz Wi-Fi or 5GHz Wi-Fi. Go to More Functions > Wi-Fi Settings > Advanced Wi-Fi Settings. Log into the router's web-based management page. This avoids multiple Wi-Fi signals on the same channel, and reduces Wi-Fi interference sources. If there are multiple Wi-Fi networks in the area, set the router's Wi-Fi channel to Auto.

For some routers that support 5G Wi-Fi and have multiple antennae, the 5G signal may be affected by moving objects.) (If your router does not support 5G Wi-Fi, please ignore this FAQ.

There are fewer interference sources on 5G networks. If your Wi-Fi signal is strong but the connection speed is still slow, try connecting to the router's 5G Wi-Fi.Obstructions such as walls between your router and device can affect Wi-Fi signal quality.

Minimize obstructions between your router and your computer or other devices.
