how to test Wireless/Bluetooth card on Fedora

hello, I am having some issues with my Bluetooth connections. I tested a Bluetooth mouse and it worked but had an issue, it became laggy after a few seconds of being connected. One would move the mouse but the movement of the pointer on the screen was noticeably laggy. I also tried using a bluetooth speaker and experienced a similar issue. The sound produced by the speaker was slightly behind the video, just slightly behind. I know that both of these devices (mouse and speakers) work correctly on other PCs. And the issues I am having on this PC, are also present on my Windows system installed on dual boot on the same machine. I'm on a Dell XPS 9550,which I think comes with the Dell Wireless 1830. and lspci outputs : Broadcom Inc. and subsidiaries BCM43602 802.11ac Wireless This card provides both Wifi and Bluetooth. My bootup is showing some messages related to this device, maybe?: [ 1838.063937] ieee80211 phy0: brcmf_inetaddr_changed: fail to get arp ip table err:-52 [ 4216.272913] ieee80211 phy1: brcmf_psm_watchdog_notify: PSM's watchdog has fired! Is there any way for me to test the Bluetooth on this laptop to see if I have a damaged card? I need to know if I need to buy this replacement card. Wifi is working OK, Bluetooth is definitely not ok (even on Windows). I'm on Fedora 34 Workstation. If I decide to order a new Card, I think I could also get the: Intel Wireless 7260 WLAN WiFi 802.11 ac/a/b/g/n + Bluetooth 4.0 Dual Band Card or the: Killer Wireless N1535 Dual Band WLAN WiFi 802.11 ac/a/b/g/n + Bluetooth 4.0 M.2 Card - VM1D6 working on this laptop. Can anyone suggest which one might work better on Fedora? thanks very much for your help. Anil F
