So I have that custom-made wifi router I've built. And it uses a USB wifi adapter with AC (wifi5) capability - the fastest one I could find in AliExpress.
I set it up a while ago - the internet access works fine, although speeds are somewhat sluggish. But hey, what to expect from a cheapo on Ali! Not to mention it's USB, not a PCIe...
A few days ago I ran a few speedtest.net tests with my actual AC router and the one I've built. Results were so different I wanted to cry :( some pathetic 23Mbps with my custom router :(
This evening I had some time on my hands and finally decided to have an umpteenth look.
nmcli d wifi
this is what caught my eye first. The RATE column listed my custom router as 54Mbps, whereas the actual router had 195Mbps.
I have reviewed the hostapd configuration sooo many times - this time nothing caught my eye as well.
Googling did not give anything obvious as well.
What do we do next? Yes, that's right - enable debug and read the logs.
> VHT (IEEE 802.11ac) with WPA/WPA2 requires CCMP/GCMP to be enabled, disabling VHT capabilities
This is one of the lines at the top of the log. Waaaaiiitttt.. VHT is something I definitely want with ac -- why does it disable that??? Sounds like a configuration fuckup rather than the HW limitation! And config fuckups CAN be fixed!
Turns out, an innocently looking
`wpa_pairwise=TKIP`
change into
`wpa_pairwise=TKIP CCMP`
made a world of a difference!
:wq
!hostapd
connect to the hostapd hotspot and run that iperf3 test again, and... Oh my. Oh boi! My pants fell off -- the speed increased >3x times!
A quick speedtest.net test deems my custom router's download speeds hardly any worse than the speeds obtained using my LInksys!!
The moral of the story: no matter how innocent some configurations look, they might make a huge difference. And RTFL [read the fucking logs]
In the pic -- left - my actual router, right - my custom-built router with a USB wifi adapter. Not too shabby!7 -
Our boss has a camera in the office to "monitor" us, the developers.
He tries to monitor our movements and record the things we say.
I'm curious, do other people do this?
I find it annoying.23 -
A non-technical colleague said she bought some bitcoin on a site over a year ago.
She doesn't remember the name of the website.4 -
Can you guess where the form fields are?
It's the grey area.
Not, not that one, the other grey area.2 -
When your minipc finally arrives, you're all excited to finally get your hands on pfsense/bsd, and you find out bsd is still struggling with wifi5, not to mention wifi6 which you've bought to have high-end networking at home..

Panic. 😟
I received two emails today inviting me for video call interviews at two companies I applied to.
I am supposed to select a date for this week or next week, but our office resumes work on Monday, the 7th.
I only have tomorrow and the day after (3rd and 4th) left for this week. I need time to prepare, so I am thinking of booking one for 4th and one for next week.
BUT
I am trying not to start the year by skipping work. I already skipped work in December because of a brief illness (lol).
I am thinking, if I go to work on that day, I might get summoned into a meeting and miss my interview. So, I have concluded that I will have to skip work on that day, but now I can't think of excuses.
Ideas? 🤔12
