hello sifu's...
want to ask..im using Yagi antenna..my signal seems full but the connection not stable..
i tried to ping www.google.com not stable at all..
Im using Huawei E1762..izit becoz the USB dongle or because signal?..or any other reason?..im trying to get better & stable connection..
thank you.
Yagi antenna is never known for stable

Please refer to 3G wiki for explanation
Users always mistaken higher dBi = more stable
dbi is only the capability, the stability and consistence is depends on the the antenna design

That's why you never see Maxis use Yagi antenna, they use panel even in Genting First World hotel
