Default Ajutor cu un Archer C7, v4, NAT Boost enabled, PPPoE reconnects

Buna.
As avea nevoie de ajutor cu pb de mai jos. Am pus si pe forumul TP-link de aia e in engleza.

Internet connectivity issue with Archer C7, version v4 with NAT Boost enabled, after PPPoE reconnects

I have the following issue with TP-Link Archer C7, version v4. [HW Archer C7 v4.0; FW 1.0.5 Build 20171101 rel.37754(4555)]
With NAT Boost enabled, after PPPoE reconnects (I suspect), the internet connection becomes unusable.

Here are a few symptoms describing the issue.
- ping is ok
- any simple google search has a delay of 5-20 seconds,
- listening to some online radio stations works intermittently - always breaking up after less than 20 seconds,
- speedtest.net cannot measure speed but shows an error,
- trying to download any file "works" in gaps, showing no progress for 5-30 seconds, and very slow progress in between
Looking into the router's log showed that every time before such an event, something NAT related is reinitialized successfully.
(multiple lines like this 2018-01-14 11:33:34 nat[1590]: <6> 211501 Initialization succeeded). I suspect a PPPoE reconnect could trigger that.
In order to fix this, I need to reboot the router every time.

I am also able to reproduce the problem manually, by disconnecting and reconnecting PPPoE from the router user interface when NAT Boost is enabled and I get exactly the symptoms described above.
With NAT Boost disabled, the issue does not occur on PPPoE disconnects, but obviously that would affect performance.
Tried all available firmware versions for Archer C7, version v4, region EU, and it happens with all of them.


Can someone reproduce this issue? I would be also curious to know how much the performance would be affected by disabling NAT Boost, say for a 300mbit connections or for a 1Gbit connection. Any advice?

La prima vedere pare e ai o problema legata de firmware (mai precis de modul in care se impaca firmware-ul cu pppoe).
Totusi, daca routerul e nou, n-ar fi imposibil sa fie unul cu defect, asadar in functie de raspunsul celor de la tplink, posibil sa trebuiasca dat la garantie.
Vezi insa si daca cumva se supraincalzeste. Fa un test asa: ii deconectezi alimentarea si il lasi sa se raceasca (juma' de ora, o ora, sau mai bine peste noapte). Imediat ce il alimentezi vezi daca mai face figuri (daca n-a apucat sa se supraincalzeasca ar trebui sa mearga OK). Dupa ce se supraincalzeste, ar trebui sa apara si problemele.

Descrierea ta imi aminteste de o problemă cu IP fragmentation, care se īntāmplă īn special pe conexiunile PPPoE. Cumva ruterul "sughite" mai ales cānd descarci fisiere ceva mai mari?

Situatia a evoluat astfel.
Am reprodus problema cu 2 exemplare de Archer C7 v4 hardware, in 2 locatii diferite cu conexiune PPPoE de la RDS.
Am testat si cu un exemplar de Archer C7 v2 hardware, acela functioneaza ok dupa disconnect, cu setarea similara.
Deci suna a pb de firmware/compatibilitate, la modelul C7 v4 hardware.

Supraincalzire nu e.
Despre IP Fragmentation nu pot sa ma pronunt.
Pur si simplu dupa un disconnect, conexiunea refacuta nu e in regula, pare a fi conectat si nu prea in acelasi timp.
De exemplu emailul de yahoo trudeste si se incarca in cateva minute, si concomitent afiseaza si ca nu sunt conectat la internet (cat timp trudeste la incarcare).
