[ThinkPenguin TPE-R1400] Decreases Internet speed significantly (325 MBit/s instead of 1000 MBit/s)

[neva_blyad]

Hi folks,

I have a good enthusiastic mood, there is IT and technology party today.
A few days ago a new ISP had come to my house. They connect us to Internet with new speedy optical fiber cable of 1 GBit/s. It is ten times bigger than previously used ISP with DOCSIS connection of 100 MBit/s. Also, the old ISP works with lags and everyone in my house hates them. So, everything promises to be fun...

But I have a problem. My router ThinkPenguin TPE-R1400 slows the new connection down in 3-4 times.

I used Speedtest by Ookla. The first test. I connected my laptop directly with Ethernet cable of ISP. The results are OK:

We see the 1 GBit/s. And the second test. I connected my laptop to router and router to ISP. The results felt down in 3 times.

We see the 325 MBit/s.
Do you know this problem?
What I have to do to fix it? (If it possible.)

P. S. The TPE-R1400 has Rockchip RK3328 Quad-core 64-bit Cortex-A53 (runs at up to 1.4Ghz), 1 GB RAM.

Is it enough for fair 1 GBit/s WAN connection, am I right?
Firmware OS is LibreCMC v6.1 (fresh september release), Linux is 5.15.164.

OS is LibreCMC v6.1 (fresh september release), Linux is 5.15.164.

Since you're not running OpenWrt, this is out of scope for this forum.

Please ask the LibreCMC folks for help.

Please ask the LibreCMC folks for help.

Why not?
It is fork.
LibreCMC has no their own community forum.

[neva_blyad]

Our OS are very close.
Why we can't help each other?

@neva_blyad

It is fork.

Precisely. The analogy I often use is to say that a fork is to official OpenWrt as corn syrup based maple flavored syrup is to pure maple syrup from a maple farm.

Their fork is very heavily modified relative to official OpenWrt and it fundamentally changes how OpenWrt operates. We are not experts in the changes they have made -- it's a black box for all practical purposes.

@neva_blyad

LibreCMC has no their own community forum.

In that case, you have two main options:

1. use other sites that have more general networking support, possibly reddit or similar.
2. Use official OpenWrt (if your device is supported) and then you can leverage our community here -- we're experts on the official version, but we cannot support forks.

@psherman

In that case, you have two main options:

No, the TPE series of ThinkPenguin targets are added to LibreCMC repos, no support in OpenWRT.

Bummer.

I guess you'll have to ask on other sites or contact the maintainers of LibreCMC for assistance.

For interests sake I had a look at what 'librecmc' is. It's a router OS forked from LEDE that use a custom kernel with only free components - no blobs.

Seems like a worthwhile effort, but has diverged a long way from OpenWRT with this custom kernel. As the OP has said they have zero support or documentation!

@neva_blyad there are a fair few RK3328 boards supported by OpenWRT, if you are up for the effort you can probably implement support for your device yourself. If that's not an option you're likely up against the restrictions from their libre kernel not allowing any rockchip firmware to be included.
In Openwrt you'll get 450mbps with SQM enabled and an easy 900mbps without SQM.
If your firmware supports it enable software NAT acceleration and IRQ balancing (or hardware acceleration if they have enabled it). Make sure no QOS or SQM is enabled - the rk3328 cannot do QOS / SQM at gigabit speed even with the acceleration OpenWRT supports.
