Môže jedna Wifi rušiť druhú?

Dobrý deň, Ahoj Riešim to už skoro rok a neviem si rady, tak sa skúsim opýtať vás. V RB mám vytvorenú LAN a VLAN. LAN je pre štandardné používanie, VLAN je p...

9 a 13. Ani sa neprekrývajú. Viem, že 13 by som (ak sa nemýlim) používať nemal, ale 9 a 13 sú minimálne obsadené.

Není tam náhodou dva dhcp servery ? vyhodil bych ten tp-link některé staré verze i když se zakáže dhcp tak i tak dávají dhcp i když je zakázané , nebo nahrát do něj openwrt

Postni sem alespoň config z mk ať můžeme vyloučit problém v mk

mirmo80

kadlcikales Nemali by byť. Oprava, hlavný router nie je C6 (ten som mal dávnejšie) ale C80. Ten je rovno v móde AP. DHCP je zakázané v WR820N. Len problém neprestal ani keď som WR820N vypol a miesto neho použil starší D-Link DAP-1160.

Takže když nastane výpadek a mobil se nechytne, zařízení na lan kabelu fingují ?, když se přepíchneš do lan toho tp-link jede net ? pozor na to ty tp-linky i když jsou v moduap někdy nechají dhcp server zapnutý nebo na AUTO pak to dělá paseku musí se dátna off , když ti mobil zahlásí že se nedostane na net v pokročilých možnostech dostaneš IP ? domnívám se že bude možná problém asi v těch vlan zkusil bych to bez nich a bez IOT , dále asi CRS není ideální mít jako router + PPPOE , dá max 50Mb/s a s malými paketama se usmaží při 20Mb/s je to sw ne router

mirmo80

kadlcikales Vyskúšať pripojenie na kábel priamo vo wifi routri ma nikdy nenapadlo. Určite vyskúšam. Tak isto som nikdy nepozrel, či má mobil pri výpadku pridelenú IP. Tak isto pozriem. Pozrel som aj DHCP nastavenie v C80, tak nie je povolené.
CRS už ale za iný nevymením. Tých max 50Mb/s myslíš, prosím, ako? Ide ku mne optika 250 Mb/s a to cez apku speedlink bez problémov nameriam.

kadlcikales

mirmo80
Myslím to tak že tenhle produkt je primárně sw , není určen jako router , nemá na to prostředky aby výkoně routoval , když přidáš více FW pravidel a na lince poběží více spojení a budeš přenášet více paketů tak dojdou prostředky a může se přenos zpomalit nebo to může způsobovat restarty atd. Prostě že to má v názvu router neznamená že to router je . Primárnê je to sw ne router

mirmo80

kadlcikales Jasne, chapem. Tak vyskusam kabel priamo na ap a dam vediet.
Dakujem

Nedávno jsem řešil u klienta podobný problém. Po týdnech laborování se ukázalo, že děti strčili do zásuvky starou wifi se stejným SSID a heslem, ale bez zapojeného přívodu dat. Nová byla v provozu přes půl roku.

basty

mirek_k jjn tohle odhalí třeba wifiman, kterým to oskenuješ a uvidíš mac ap co tam nemá být.

mirmo80

mirek_k Bodaj by to bol môj problém. No moja druhá Wifi má iný názov a iné heslo.

sidi Neviem vylúčiť, či sa od netu neodpájajú aj IoT zariadenia. Ak sa to ale aj deje, nikdy to netrvá tak dlho, aby sa to prejavilo. Resp. nikdy som netrafil ten moment, aby zariadenie dlhšie nereagovalo, alebo bolo nedostupné cez mobil/apku. Nejaké to +/- oneskorenie je ok. Navyše, tento problém sa začal prejavovať až vtedy, keď som doma zapol druhú Wifi.

Prehodil som káble tak, že noťas je káblom priamo vo wifi routri. Tak budem testovať.
Ďakujem všetkým za reakcie.

mirek_k

basty Jasně, není těžké na to přijít. Ale projevovalo se to hodně zřídka a kovid, tak jsem to řešil s klientem po telefonu.

sidi

Zkus odpojovat IoT zařízení od sítě, jestli nějaké nedělá bordel. Zažil jsem, že Chromecast připojený na wifi celou wifinu shodil, stejně tak tiskárna.

mirmo80

Tak dnes výpadok, pozrel som to cez apku WiFiman a vyzeralo to viď. screeny z mobilu. Net na oboch wifi nedostupný. IP pre mobil pridelená. Pozrel som to potom aj v nastaveniach Wifi v mobile. Mac pripojený cez kábel priamo to routra TP-Link_Home. Tak isto net nešiel, IP pridelenú mal. Stihol som ešte prehodiť kábel do mikrotiku, no net aj tak nešiel. V logoch mikrotiku nič. Nechápem už v čom môže byť problém. Čo ešte môžem kontrolovať/sledovať? Ešte mám log z wifi routra a tam je tiež pár logov error v znení "lan not find"

sidi Určite vyskúšam aj tvoj tip, ale to si nechám nakoniec, pretože problém nebol do vtedy, kým som nezapojil wifi guest. IoT zariadenia sme už ale mali aj pred tým.

mirmo80 Já neřešil, zda se IoT zařízení neodpojují, ale zda ti dané IoT zařízení nezpůsobuje zmiňované pády sítě - tzn zařízení je dostupné, ale udělá v síti takový bordel, že nic jinýho nefunguje.

mirmo80

sidi Jasné, pochopil.

Tak dnes som si (asi definitívne) potvrdil, že problém bude (zrejme) v mikrotiku. Net za ONT zariadením som cez switch poslal do mk a nejakého základného tp-linku. Dnes "výpadok" a kým za tp-linkom všetko fungovalo (wifi, aj LAN) tak za mk absolútne nič. Notebook, mobily (wifi, kábel) ani ťuk. Jediné čo šlo, pripojiť sa k mikrotiku cez winbox. Nepomohol ani reconnect (s pridelením novej IP od isp), restart mikrotiku, nič. Vôbec netuším kde by mohol byť problém. Práve je dostupný update, tak som mk aktualizoval a nič. A potom ako by sa nechumelilo, všetko nabehne ako by sa nič nedialo.
Vôbec neviem kde začať, ale asi resetnem konfiguráciu a začnem úplne od začiatku.

=> Wifi xyz pravdepodobne nie je pripojená na internet...
Nemusí súvisieť s rušením, ale s tým ako zariadenie zisťuje dostupnosť internetu.
Na OS MS Windows sa napríklad stáva trocha iná zvláštna vec a to, že to tiež niekedy ukazuje "bez internetu", ale internet pritom funguje. Vo vašom prípade by som súčasne pingoval ip adresu routra a ip adresu WAN rozhrania routra, alebo nejakú ip adresu na infraštruktúre ISP. Ak by ping na router išiel a ďalej už nie, tak môže byť zahltená prekladová tabuľka NAT.

dva dhcp servery?

mirmo80

hapi Ano. Jeden pre LAN, jeden pre VLAN.

mirmo80

hapi dva dhcp servery?

Môže v tom byť, prosím ťa, nejaká súvislosť?
Ďakujem

mirmo80 vypni si DHCP, ze ktereho mas dostat IP adresu a sleduj, zda dostanes jinou a od koho ipconfig /all a uvidis IP adresu DHCP serveru.
