Hi guys, I just bought a Celcom Wireless Package (150) for my parent in kampung. I got a few advice needed for Huawei B618.

1. I need to improve on Celcom Network Signal, I just google out the antenna but there is no proper review for them. Any recommendation for antenna? my budget is plus minus RM100-200 for antenna.

2. I need to improve on WiFi signal as well, the 1st floor (where the modem is located have good coverage), but weak coverage on 2nd floor. Any advice on to improve my Wifi?
