caute

mam rb,na nom je cez wifi 2,4g napojeny klient ovis 5460 a za nim router
pingujem z winboxu tieto veci:

A. ip ovis 5460 cez arp
B. ip ovis 5460 cez ICMP
C. ip routra cez arp
D. ip routra cez ICMP

Problem : vypadava obojsmerna komunikacia z ap na klienta
klient je stale v tabulke asociovanych MAC
signal je perfektny - CCQ 99% ,signal strength -62
v logu nic nieje
wds nepouzivame
skusal som aj pozriet FREQ. usage pre pripad ze by to dakto rusil ale je to ok.
kodovanie je wpa2 aes

v urcitych momentoch vypadne pingovanie A a C (teda arp nejde ,ale icmp ide)
v inych momentoch vsetky nejdu - ani arp ani ICMP

toto je situacia ked je vsetko ok (ale tie 900ms arp sa mi nezdaju)
100.252 - ovis ap
100.200 - RB
55.124 - router
55.1 - RB



toto je ked vypadne arp ale icmp ide


situacie s arp sa striedaju cca za 5 minut - 5 minut ide,5 minut nejde

viete mi poradit v com je problem?


vdaka

Problem je v tom ovislinku - ked ovis v rezime klient, tak prepisuje mac adresy zariadeni za nim za jeho MAC adresu. A vtedy za nim nemoze byt ina siet, resp. router. Nefunguje to, robi cudne veci (na to si uz prisiel)
Mas dve moznosti:
1. daj ten ovis prec a pouzi wifi kartu priamo v tom routri
2. spravit WDS, vtedy by to malo ist.
