WiFi performance depends on router placement, device distance, wall thickness, and interference from nearby electronics.

• Place the router in an open and central location.
• Keep it away from microwaves, Bluetooth speakers, thick walls, and metal cabinets.
• Use 5GHz near the router for better speed.
• Use 2.4GHz in far rooms where range matters more.
• Restart the router occasionally and keep your router firmware updated.

2.4GHz Band

• Better range and wall penetration.
• Works well with older devices.
• More affected by interference from microwaves, Bluetooth, and nearby routers.
• Lower maximum speed compared with 5GHz.

5GHz Band

• Much faster speed when close to the router.
• Less interference in many homes.
• Shorter range than 2.4GHz.
• Does not pass through walls as well as 2.4GHz.

Recommendation

• Use 5GHz when you are close to the router and want best speed.
• Use 2.4GHz in far rooms or through multiple walls.
• If your router supports dual-band, keep both networks available.

Mbps means megabits per second, which is how internet providers usually measure speed. MBps means megabytes per second, which is how files and downloads are often shown.

Conversion

1 MBps = 8 Mbps. For example, a 100 Mbps connection can show around 12.5 MBps download speed, and 1Gbps can show around 125 MBps under ideal conditions.

BDIX means Bangladesh Internet Exchange. It is a local peering system where Bangladeshi ISPs exchange local traffic directly.

Benefits of BDIX

• Faster access to local content and Bangladeshi websites.
• Better local streaming, IPTV, and FTP performance.
• Lower latency for supported local services and gaming servers.
• Reduced dependency on international bandwidth for local traffic.

Sarker Net BDIX Speed

Sarker Net provides BDIX Speed up to 1Gbps for supported BDIX and local cache services.

LAN cable gives a direct connection to your router, while WiFi speed can change because of distance, wall thickness, signal interference, device quality, and router placement.

• Use LAN cable for gaming, office work, smart TVs, and high-speed downloads.
• Use 5GHz WiFi near the router for better wireless speed.
• Use 2.4GHz when you need more range in far rooms.
• For best results, keep your router high, open, and away from heavy electronics.
