Why does my MacBook Pro have long ping times over Wi-Fi?
- by randynov
I have been having problems connecting with my Wi-Fi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10 seconds before slowly coming back down. You can see the trend below. I'm on a MacBook Pro and have done the normal stuff (reset the PRAM and SMC, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be.
The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 and 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel.
1 - How can I figure out what's going on?
2 - How can I correct the situation?
