Administrators Hervé Posted May 3, 2020 Administrators Share Posted May 3, 2020 It's quite normal that a much increased latency reduces overall bit rate. If latency is beyond your Box/router, there's nothing you can do about it. Most likely, it's on your own wireless connection. If you're on a 5GHz network, distance and obstructions (walls) affect performance quite sensibly. But I believe you'll still suffer without DFS being available on your connection. https://netbeez.net/blog/dfs-channels-wifi/ All in all, it's not really a Hackintosh issue per sé. You could run batches of ping tests to your local router to see how that behaves. Typically, all should be within 5ms. What are your current settings? Did you experiment as I had previously suggested? Quote Link to comment Share on other sites More sharing options...
djuby Posted May 3, 2020 Author Share Posted May 3, 2020 Hi Hervé, Yes, I tried all your suggestions, but the issue is still there. The laptop is located around 10 feet from the router and always connects to the same SSID. Here is a screenshot of my ping times to the router - first one is after wake up from sleep, second one is after system restart. Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 3, 2020 Administrators Share Posted May 3, 2020 12 to nearly 110ms! That's a hell of a jitter on the local wireless network. At a distance of 10ft and on a 5GHz network, you should be within 5ms unless your network is saturated with traffic of course. So, yes, definitely an issue with your laptop settings on Wake.

djuby Posted May 3, 2020 Author Share Posted May 3, 2020 How can I check the card model? Do I have to boot into Windows? Quote Link to comment Share on other sites More sharing options...
djuby Posted May 3, 2020 Author Share Posted May 3, 2020 Checked in the BIOS - says Broadcom Wireless, but nothing else. Quote Link to comment Share on other sites More sharing options...
djuby Posted May 3, 2020 Author Share Posted May 3, 2020 Checked on Dell support site with the service tag - DW1830 3x3 802.11ac 2.4/5GHz + Bluetooth 4.1 Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 3, 2020 Administrators Share Posted May 3, 2020 You know the simplest way to check is to open up the laptop. Just remove the back/bottom cover and look at the wireless card near the fan! Model is usually written on the label. Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 3, 2020 Moderators Share Posted May 3, 2020 The DW1830 requires 3 antennas. Did you plug in all 3? Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 3, 2020 Administrators Share Posted May 3, 2020 Seen your above edit re: ping tests. Why don't you take an IOReg before and after wake so that we try and compare things in the wireless front? Quote Link to comment Share on other sites More sharing options...
djuby Posted May 4, 2020 Author Share Posted May 4, 2020 Here are the IORegs before and after sleep. I have checked the WiFi card and and all antenas are connected properly. Archive.zip Quote Link to comment Share on other sites More sharing options...
