So my mom told me I should stop playing games...

....When she literally saw me flashing OpenWrt in a Linksys router...

so my parents live close and my dad said his router died. I told him I had a spare. I loaded it dd-wrt on there and next time I went over there he asked about opening a port. I said I could do it for him. wouldn't let me touch it. he believes he is the computer genius and that I would brake it.

funny part is I work on servers for huge companies like Wells Fargo, Ally Bank and tons of others. I can configure a rack mount router but he doesn't trust me to touch a little crappy home linksys router lol.

no matter how smart you are they never want to admit their kid knows more about tech than they do.

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!

I don't rant about shit often, I need to get this out of my head.
So I purchased two Linksys routers about 2 years ago, and in the span of this month both of them effectively died after power loss...
They still kinda work, but both stopped detecting internet so because it's kinda their job to do that.. they are useless at this point
The models are WRT 1900ACS and MAX-STREAM AC1750

Now for the tin foil hat stuff - they both had 2 year warranties, that expired a few months ago, maybe planned obsolescence?

I know everyone hates when people ask them for help with fixing IT related stuff.

I have a different approach to all similar questions. I don't get upset or anything, I just tell them that the device they have is a little bit shit, and suggest them buying a new expensive one that is better and will do all that. Your router isn't working as you want? Buy a Cisco (a real one with $1k+ price tag, not that Cisco branded Linksys garbage). Your printer isn't working as you want? Buy some high end Brother stuff. Etc...

After first few times they just stop asking...

I hate the US education system, its just designed to fuel capitalism. It keeps getting less funding so that actually passionate, intelligent people get kicked out and replaced with people who only want to be a teacher so they can have power over others.
Why do they block news websites? Why do they block github, so their own robotics team can't even access the essential building blocks for the robot? They make everything more complicated and for the reason that it might distract you. Maybe just make topics engaging and not boring asf, just cramming for the exams so the school gets more funding. Maybe prepare students for jobs, allow them to do projects, pursue classes that interest them, and have any sense of individualism.
Anyways, yeah, the school blocked github so I can't do my FBLA project, I can't access the code for programming our robot for competitions, I can't even download software required for half of these classes. I have a Linksys router, is there any way I could set it up to bypass the firewall?

The secondary access point stopped working, turns out the date/time is wrong. You guessed it, the ntp server is hard-coded in the firmware (last version), no option to change it, it a linksys but not supported by openwrt.
Grabbed a second one, flashed with openwrt, same shit, and can't access by ssh because it's an old dropbear build.
Hate trashing things, but sometimes too much is too much 🍺

If there is tech support that is just plain awesome, it these:
1) Namecheap
2) Newegg
3) Nyko

The ones that are meh include:
1) Linksys
2) AOL
3) Microsoft
