upgraded ISP bandwidth, WiFi doesn't see the increase

in WiFi - General Questions

WG M370; FW:12.10.4, AP325 v11.0.0-36.4
Desktop Gigabit nic; Laptop Intel WiFi 6 AX201 (160MHz)
AP325 radio (5GHz); mode 802.11 N/AC; channel- Auto; channel width 20MHz; power-Auto

We upgraded our fiber ISP from 200Mbps to 1000Mbps, my desktop speed test shows 688 Mbps downloads / 681 Mbps uploads.
My laptop (WiFi) speed test shows 144 Mbps downloads / 78 Mbps uploads.

Am I missing a setting or a setting I need to change?
Does the AP325 pass the additional bandwidth or is it limited to a lower bandwidth?
This is the first time we have increased our bandwidth and it hasn't been the same across the network.
I have 3 - AP325's that need the extra bandwidth.

    Hi @bford

    You'll see the best performance on 5GHz channels. Generally, 40- or 80-MHz channels perform better when the channel space is clear, and your devices support wide channels. If your air space is congested, sticking to 20MHz channels may be required.

    -Your laptop will need to have a 2x2 radio for best performance.
    -Your laptop will need to have a WiFi card that supports Wave 2 AC or better for best performance.

    Based on the hardware specs you listed, the biggest impact would likely be increasing your channel width on 5GHz. Keep in mind that your other devices on that WiFi network will need to support this for the best performance.

    From the hardware guide, the absolute max throughput for the AP325 is:
    2.4GHz, 802.11b/g/n. Max datarate: 300Mbps
    5GHz, 802.11a/n/ac. Max datarate: 876Mbps
    Please keep in mind that this is the total throughput for the AP, not the throughput for a single client.
