5G dropping packets when iPad is close to device
Hello,
I recently purchased the iPad 9th gen and I suffer packet loss from the beginning of using it with my AX10 on 5Ghz network. However the issue only appears when the iPad is in direct line of sight of the router. When I move to the next room behind the wall or even behind the corner, the issue goes away.
The issue appeared even on the previous router FW version and previous iOS release and the iPad is the only device with this issue, however it's the only 802.11ac portable device that I use. (Otherwise we have 2 iPhone 12 which support the 802.11ax standard)
I have a 1Gbps fiber connection and on the phones it's stable at ~700Mbps with no packet loss. I also use the Archer C6 router at work and the iPad has no issues with it's 5Ghz band.
AX10 WiFi config:
OFDMA on
TWT on
Smart Connect off (2,4G and 5G bands are separated as the 2,4G is used only for smart-home appliances)
5G settings:
security WPA2/WPA3-Personal
Version Auto
Transmit power High
Channel width 80Mhz
Channel 48 (pretty much the best I could use regarding the local interference)
Mode 802.11a/n/ac/ax mixed
Below are the ping results from AX10 to iPad
Direct line of sight
