Na forum.mikrotik.com su na toto zariadenie same negativne ohlasy....defaultne ide zle(vysoka latencia, slaby signal), s externou antenou to iste.
Mate niekto skusenosti? Vratit to alebo su nejake nastavenia co to dokazu spojazdnit slusne? |

Jeden kus som si kupil ako domacu wifinu a zatial bez problemov, signal celkom slusny, bez tuhnutia, latencie v normalnej urovni.
Mozno zalezi od kusu |

teda by soom niekoho nezavadzal, presny model je RB751U-2HnD. ROS 5.14
DHCP server a klient, PPTP tunel (1), wifi + nat
pri tcp teste da 18Mbsp (CPU na 100%) so stratovostou
pri tcp, strop nastaveny na 5M (cpu do 27%) ping 6-10ms (bez zataze 6-7) |

nevyriesil, to sa ani neda....velmi vela ludi je nespokojnych, par ludi pise ze im to ide ako tak....idem to vratit spat.....vyzera ze par serii im mozno vyslo....ale mikrotik sa k tomu nevyjadruje, tak isto ako 951 placu.....ze to vobec dali do predaja.....vela ludi im to vracia....vsetci cakaju na rb2011us....
Ak by ste mali niekto funkcny routerstation na predaj, rad od Vas kupim ten siel s cm9 ako hodinky.....
Code: › We've started deploying this device when it was launched, we have about 50 of them in the field.
We must say, we had lots of trouble with this device (concerning wireless). We've made tons of supout's and Mikrotik did lots of efforts to fix it. It went better when ROS version nrs increased, but it still ain't stable as we expected. We 've ended up reconfiguring most of them without any wireless activated and added an extra ubnt access point to obtain wifi. These configurations are as good as 100% stable. Still sad it's a no go with RB751-2HnD and wireless enabled as price is good, but we can't afford to loose stability. Loosing stability is loosing customers and we can't risk that. For this reason we discontinued using this device in new deployments.
kind regards

Aktualne mam s nimi problemy, nezvladaju viacerych klientov, mam ich nasadene ako hotspoty. latencia lieta, rychlost 3Mb.. Dufam ze na nieco pridem a zistim preco chodia tak zle. Potom podam info.
btw, nemate link na nejaky dobry, odskusany setup pre Routerboard AP pre 2.4 Ghz N-kovych klientov?
aktualne mam 3 APcka pokryvajuce volne priestranstvo, klienti su vsetko mozne, mobilne telefony, notebooky...
