What would you give up to save this #planet?

It's always so easy to demand that the rich should give up their yachts and private jets because you're not affected by it yourself. Those who don't have a car and live in the city demand the abolition of the car without thinking about the people in the countryside. Those who don't use AI and streaming are calling for data centers to be shut down to save power.

But what if it affected us? How much #Internet #bandwidth could we sacrifice if it meant saving the planet?

(Who now writes in the comments I only use text messages for chatting so I don't care about the bandwidth. I would like to congratulate him because he still has not understood what it's all about.)

Given less voyeurism, testing bandwidth can also be done this way and with less side effects. Set desired bandwidth with e.g. -L 12M for 12mbps and send them a constant stream with they pipe into /dev/null like this:

pv -r -L 32M /dev/urandom | ssh user@my.testserv.er "cat > /dev/null"

On Gentoo pipe view pv is available as sys-apps/pv.

How to (not) extend Wifi coverage of Starlink (Wifi) Accesspoint

intro:

would the user pay 100€ per month for a super fast uplink (in this case Starlink, x>150MBit/sec!!! (it (of course) fluctuates, also there is a BATTLE going on between SpaecX (StarLink) & Amazon (Project Kuiper) which could lead to turbulanecs)

and then have it all ruined by unreliable and slow Wifi routers & maybe bad (wet?) LAN copper cables?

no of course not!

what works better?

actually an older tp-link router, the former “workhorse” wr841n v10 (!!! WARNING ONLY THE v10 has DETACHABLE ANTENNAS!!!) + outdoor yagi antenna (2.4Ghz only) performs better than the newer TL-WA901ND v5!

(very minimalistic hardware specs of this router: RAM MB: 32 + single core CPU: Qualcomm Atheros QCA9533-BL3A@650Mhz)

how to best test bandwidth?

in the browser: there are the (obvious notorious) internet bandwidth benchmark test websites

  • https://fast.com/
    • very basic if basic is enough
  • https://www.nperf.com/
    • plots a graph
  • https://www.speedtest.net/
    • speedometer
  • in the GNU Linux bash terminal: via this script:
    • what it does is download a file of exact 100MBytes random data from a (usually) very fast datacenter in Germany
    • the advantage of this: it is very easy and fast to be fired up via press Cursor-Up and ENTER to re-run it again and again and compare the results with past results

Starlink + TP-Link (as wds-bridge or repeater) = does it uplink?

yes it does! the TL-WA901ND hardware v5 has many wifi modes and can confirm they work (but not fast & reliably):

  • TL-WA901ND v5 <-wds-bridge-> TL-WA901ND v5
  • TL-WA901ND <-wds-bridge-> Starlink Original Wifi AP

what is great about this product: it has wifi modes no other product offers (used that bridge with ap mode for years)

this is a screenshot of older firmware: (more green than cyan)

problem: DOES NOT WORK AS FAST & AS RELIABLE AS IT SHOULD!

while Bridge-with-AP seems catastrophic unreliable (outages every few minutes disconnect/reconnect)

what works a bit better is wds-repeater mode, but still not great.

vs

lenovo t440 <-> TL-WA901ND v5 <-> brick bandwith benchmark:

so when directly connecting to Starlink AP via WIFI the speeds are amazing! 🙂 ~10MBytes/sec!

when going through the wds brige… it is bad (it could also be that something is blocking the wifi signal too much and do not have a 5Ghz yagi antenna here)

So now my mobile provider has granted my unlimited mobile data use, for almost two days. (I dunno why, a promotion of some kind. My haphazard guess is, they couldn't risk it on the day the German national team played, which was yesterday, and maybe had initially reserved it for the quarter final or whatever. Who cares.)

For testing I might peruse any or all of these, which works great for testing throughput as long as you have a shell:

However with an android phone, how do I even output to /dev/null? For now I'd think I'd be tethering to my linux laptop...
