Re: Issue with ATH10K driver with 802.11 a/g mode datarates
You normally need to add 30-60 db of attenuation to get best throughput when directly cabling with SMA cables. Please try adding more attenuation. What firmware are you using on the T1024RDB? Maybe also try using a different firmware version to see if that helps.
