Dendrobatus Azureus<p>As you can see this mobile provider is now running at the good 4G+ speed.

Dendrobatus Azureus<p>I just did a speed test from my current bandwidth provider. As I've said before I use 4G plus Internet because it's magnitudes faster than the 10MBit/s which the xDSL provider gives with which are the most I can get 3.2 TBytes per month</p><p>1TB=1024GB</p><p>I will never be able to fill a proper hard drive in one month at such speeds. A proper hard drive is 16 TB at minimum</p><p>The speeds are oké for this Point in Time </p><p><a href="https://mastodon.bsd.cafe/tags/ISP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ISP</span></a> <a href="https://mastodon.bsd.cafe/tags/xDSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>xDSL</span></a> <a href="https://mastodon.bsd.cafe/tags/4G" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>4G</span></a> <a href="https://mastodon.bsd.cafe/tags/LTE" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LTE</span></a> <a href="https://mastodon.bsd.cafe/tags/network" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>network</span></a> <a href="https://mastodon.bsd.cafe/tags/data" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>data</span></a> <a href="https://mastodon.bsd.cafe/tags/speed" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>speed</span></a></p>
Dendrobatus Azureus<p>My mobile data ISP delivers much more modern speeds.

As I've said a couple of days ago, I do not intend to go back to the obsolete xDSL connections that my provider gives.

It is paradoxical, but the two 4G+ and 5G providers that the country has, give speeds which are up to par with what you can get in Europe most parts of Asia even in Russia.

I included the snapshot of the Simple GSM because Of The following,

It has come to my attention that my xDSL provider, which is also a 4G provider, suddenly needs about 60 to 90 seconds before they initialize is standard GSM Sim.

WTF? That takes as long to initialize their obsolete xDSL router and Gateway.

It is yesterday night at about 2200 hours that I found out why. They run and extensive script with you checks if your is installed in a mobile WI-FI Gateway / router

When the script has determined that the SIM is not in a phone, it delays the authentication sequence of the SIM indefinitely.

You see the SIM card going from no access to limited access, and it stays there for more than 600 seconds! Then they fail the process!

This is a classic case of Denial Of Service.

I'm so glad that I only took 3 days I'll jump to the other provider again afterwards

#WTF#GSM#4G

Since I am now not stuck with one ISP giving mediocre internet speeds on obsolete xDSL systems the following has been measured

This is a speed that I get over 4G Networks. What immediately jumps into your eyes is that the speed is almost symmetrical. When providers can give speeds like this and give 4G + speeds at 40 MBit/s you realize how mediocre 10 MBit/s is with just five megabits / seconds up

#4G#LTE#network

I've stopped working with obsolete xDSL network devices. I have an ISP Fiber to the CURB and Fiber to the Home simultaneously just to make money. They installed the obsolete fiber to the curb systems to milk people into making them think that xDSL is a way for the future.

Meanwhile on quite stable 4G Networks they give the speeds that you see in the screenshot. I can reach more than 40 MBit per second! I would rather be ad hoc on the internet, then have a slow obsolete 10 MBit connection over two copper wires.

I am finally enjoying the internet again when it comes down to speed

#ISP#xDSL#FTTH

This is the speed that I get from my ISP in Mobile mode. They are a telecom so they also have mobile networks. This speed is good in comparison with the speed that I had on their xDSL. The difference is the enormous amount that they charge for a relatively normal speed on mobile networks

@landley @jschauma @ryanc @0xabad1dea yeah, the exhaustion problem would've been shoved back with a #64bit or sufficiently delayed by a 40bit number.

Unless we also hate #NAT and expect every device to have a unique static #IP (which is a #privacy nightmare at best that "#PrivacyExtensions" barely fixed.)

  • I mean they could've also gone the #DECnet approach and use the #EUI48 / #MAC-Address (or #EUI64) as static addressing system, but that would've made #vendors and not #ISPs the powerful forces of allocation. (Similar to how technically the #ICCID dictates #GSM / #4G / #5G access and not the #IMEI unless places like Australia ban imported devices.

I guess using a #128bit address space was inspired by #ZFS doing the same before, as the folks who designed both wanted to design a solution that clearly will outlive them (way harder than COBOL has outlived Grace Hopper)...

If I was @BNetzA I would've mandated #DualStack and banned #CGNAT (or at least the use of CGNAT in #RFC1918 address spaces) as well as #DualStackLite!
