Vrlo dug post!
Saga traje oko 3 mjeseca (6 mjeseci ako ćemo gledati pesimističo stanje), a u zadnje vrijeme više nisam pametan zeza li me operater, oprema ili postavke mreže pa bih cijenio savjet, prijedlog, bilo što prije nego počnem prodavati opremu, slati na RMA i vratim se na opremu od 200kn. Već sam toliko para i vremena potrošio na mrežu za 10-ak klijenata da to nije baš normalno.
Cilj mi je samo imati funkcionalnu mrežu, bez potrebe za pristupom web UI-ju na duže od 10 dana. Kako radimo od doma, uvjet je i dobar QoS koji može rasporediti 50ak Mbps na 2-3 uređaja istovremeno. Samo i isključivo iz ovog razloga sam se odlučio na upgradeanje kućne mreže. Prvo B818 modem, pa na kraju i bolji wifi ruter.
Bio sam laik za mreže, ali u ovih pola godine sam pun k naučio - osim linux komandi i skripti za router management. Tu sam još na razini c/p naredbi bez puno razumijevanja i sl.
Krenut ću od problema, pa opisati setup i postavke.
Problem (tl;dr verzija, kasnije ću ga detaljnije opisati):
Wifi router mi ponekad ne želi povući WAN IP od operatera i onda ostanem bez pristupa netu sve dok manualno ne restartam wifi ruter ili barem WAN interface. Problem je otpočetka tu, u početku sam često rebootao ruter i upoznavao se. Promjenio sam nekoliko firmwarea i sada imam filing da se taj problem događa preredovito i zapravo je jedini problem koji me muči s tim ruterom. Nažalost, nije sjajan kako sam očekivao.
Setup:
- ISP je T-Mobile (Gigabox), APN je internet.ht.hr. Nalazim se iza CGNAT-a.
- Modem je Huawei B818, factory resetiran, ugašen wifi i prebačen u bridge mode. Opcije koje ne koristim sam ugasio. DHCP server nisam ugasio prije prebacivanja u bridge, ali kod prebacivanja u bridge WAN IP se uredno prosljeđuje wifi routeru i rekao bih da firmware to uredno hendla (slika). Nakon prebacivanja u bridge, DHCP opcija više nije dostupna u GUI-u. Probao sam ugasiti DHCP prije prebacivanja u bridge - sve puca na ruteru, nema neta, ne dobivam WAN IP.
- Router je Asus AC86U. Linkam neke od bitnijih postavki da bi se stekla kompletna slika setupa, ništa zahtjevno. Već mjesec dana ga debagiram i setup je potpuno minimalistički. Sve što ne trebam, ne diram. Drugim riječima koristim je kao precijenjenu plastičnu kutijicu s antenama.
- Switch je TP-SG108E, ima nešto malo opcija za management, ali ne koristim ništa. Factory reset, plug n play. Prije njega sam imao unmanaged TP-SG-105.
- Koristim kupovne gotove LAN kablove (Intellinet), promjenio sam ih tucet, a na kritična mjesta sam ubacio SFTP kablove.

Modem je u bridgeu pa se nema što puno prikazati osim da uredno prosljeđuje dodjeljeni IP wifi ruteru:

Ruter uredno dobiva IP, a mislim da su i ostali podaci u skladu s normalnim:

WAN postavke (probao sam sve 3 DHCP query postavke):

LAN postavke (probao sam za gateway upisati IP modema 10.0.0.1 ali tada sve puca, nema WAN IP-a ni neta):

Kako to izgleda kada se problem NE pojavi: modem se, nakon isteka DHCP leasea, a češće i ranije, rekonekta na 5 sekundi i dobije novi IP. Ruter istovremeno rekonekta WAN port i kroz 10 sekundi povuče novi IP i sve pet!
Na modemu to izgleda ovako:
Code:
2021-05-02 23:01:39 WAN connection INTERNET_VOICE_TR069_R_UMTS1:IPv4 disconnected
2021-05-02 23:01:44 WAN connection INTERNET_VOICE_TR069_R_UMTS1:IPv4 connected
A u isto vrijeme, na ruteru to izgleda ovako:
Code:
May 2 23:01:41 kernel: eth0 (Int switch port: 3) (Logical Port: 3) Link DOWN.
May 2 23:01:42 WAN Connection: ISP's DHCP did not function properly.

May 2 23:01:45 kernel: eth0 (Int switch port: 3) (Logical Port: 3) Link UP 1000 mbps full duplex
May 2 23:01:47 WAN Connection: WAN(0) link up.

May 2 23:01:56 WAN Connection: WAN was restored.
Evo kako to izgleda kada se problem pojavi:
Na logu od modema nema promjene:
Code:
2021-05-03 14:48:50 WAN connection INTERNET_VOICE_TR069_R_UMTS1:IPv4 disconnected
2021-05-03 14:48:54 WAN connection INTERNET_VOICE_TR069_R_UMTS1:IPv4 connected
Na ruteru dođe do kurcšlusa. WAN port se rekonekta, ali DHCP server ne radi, dok log počne biti zatrpan raznim DHCP statusima uređaja s mreže i to traje u beskonačno:

Problem se javlja iako sam:
- Probao drugi modem Huawei B535 modem + druga T-Mobile data kartica isto iza CGNAT-a (ovdje su mi Tele2 i A1 loši za duži test i ne mogu toliko trpiti loš net zbog posla),
- Probao koristiti modem u automatskom setupu spajanja na LTE frekvencije i u manualnom modu da se spaja samo na određene frekvencije,
- Promjenio sve LAN kablove u setupu,
- Promjenio switch,
- Izbacio iz jednadžbe većinu wifi/LAN klijenata na određeno vrijeme,
- Koristio wifi router u potpuno stock stanju, bez guest mreže, samo inicijalna zaštita wifi mreža,
- Probao različite verzije Asus stock i Merlin firmwarea, 384.x i 386.x baze,
- Nvram erase na Asusu, tzv nuclear reset,
- Probao različite WAN postavke na AC86U (continuous, normal i aggressive),
- Probao druge DNS servere u WAN postavkama,
- Razbacivao uređaje po stanu u nadi da ih jebe neka interferencija ili podzemne vode.
Problem se NE javlja kada:
- Koristim B818 kao ruter,
- Prebacim AC86U u AP mode i nakačim ga na B818.
Nažalost, kada mi B818 ruta mrežu, trpi mi QoS (bufferiranja po različitim uređajima/uslugama) i imam taj iritantan problem s njegovim wifijem - neki IoT uređaji kao da "zaspu" i hoću kresnuti svjetlo - ne trza. Treba neko vrijeme ili wifi reconnect da proradi.
Kada koristim Asusa kao AP - wifi radi super, ali QoS je i dalje loš jer ide preko B818.
Isti problem sam imao i ranije sa jednim TP-Link wifi routerom, o čemu sam pričao ovdje. Tek sad mi se čini da je i taj TP-Link možda imao isti problem kao sadašnji Asus - česte poruke u logu "[wan]Wan ethernet port plug off":
http://forum.pcekspert.com/showthrea...35#post3493735
Imam mogućnost za RMA svih mrežnih uređaja, ali odakle krenuti? Modem sam eliminirao korištenjem drugog modema, a ruter jebemu kad radi onda radi ko puška. Da je mušićav, mušićav je i jedino na tu kartu ga mogu slati nazad Amazonu. SNB forum ima pun klinac "WAN dropped" tema, ali šta je to? Bad design, osjetljiva oprema ili pimplav firmware... Je li T-Mobile u banani? SZK me ne jebe 2% jer mi je modem u bridgeu i upućuju me na, kako je oni zovu, premijum SZK gdje se pozivi fino naplaćaju po minutaži. Doduše, kada je B818 u ruter modu, onda sve radi tjednima.
