Default Internet instabil se deconecteaza frecvent

Salutare,

Imi cer scuze daca nu am postat in rubrica potrivita.

Problema este urmatoarea: am abonament la internet de la RCS si folosesc router Tenda.
Frecvent ( la intervale de 1, 2, 3, 15, 30 minute, "random"), se deconecteaza cateva minute. In browser: "This page cannot be displayed").
Am incercat cu un alt router, alt model. Acelasi simptom.
Daca netul nu "cade" de tot, viteza scade undeva pe la 27 kbps.
Mentionez ca in general conexiunea la internet este foarte rapida, insa de cand a aparut aceasta problema, se intampla de zeci de ori pe zi.

Am incercat sa scot cablul ethernet din router si sa il conectez direct la laptop.
Surpriza, se intampla la fel...Insa ceva mai rar, in sensul ca poate functiona si cateva ore fara problema...Deci ceva mai bine...

Ca idee, cu router - de zeci de ori pe zi
fara router (conectat la laptop) - de cateva ori pe zi

Sfaturi? Multumesc anticipat.

Windows 10. Sistemul de operare cu licenta, a venit preinstalat si pe desktop si pe laptop.

As mai adauga ca atunci cand se intampla, nu pot accesa (temporar) http://192.168.0.1 (pt. admin router).

O problemă asemănătoare am întâmpinat și eu, dar la mine a fost din modem/router. Dacă zici că la fel se comportă și când ai încercat alt router, iar atunci când ești pe ethernet se deconectează dar mai rar, exclude posibilitatea ca amblele plăci de rețea (wireless/wire) să fie defecte. Ai încercat un reinstal de Windows? Știu că nu sună foarte "pro" metoda asta, dar uneori acel sistem de operare de asta are nevoie, o copie fresh.

La fel am patit si eu, de aceea te-am intrebat ce win folosesti, eu aveam win 10 pro, dupa ce am reinstalat totul din nou pe curat a revenit la normal.

Ar mai putea fi doua cauze : ori iti stie cineva userul si parola de la internet ori vreun puțoi se ține de glume proaste și te flodează.

As banui un contact imperfect la cablul de retea uplink (banuiesc ca inca esti pe cupru, nu pe fibra). Fie e mufa deformata / ceva contacte oxidate, fie e un fir care nu face contact OK. Taie mufa cablului de retea si sertizeaza alta mufa.

La fel iti recomand si eu, sa verifici cablurile / mufele incepand de la cea care iti intra in router (wan port - de la RCS & RDS) precum si cele de la router la pc-uri. Foloseste un cablu sertizat din fabrica care sti sigur ca functioneaza perfect si testeaza cu ala. Ti-as mai recomanda sa verifici si pinii la toate mufele mama ale routerului, sa fie curate, neindointe, sa nu lipseasca vreun pin etc... si apasa-le usor pe fiecare sa vezi daca nu cumva sunt rupte intr-o parte iar cand bagi mufa se intrerupe contactul.

Un tester de retea ti-ar fi foarte util acum... dar banuiesc ca nu ai unul la indemana.
Altceva nu imi vine momentan in minte...
