The connection to my work wifi just failed and below the network my phone is saying "Avoided poor Internet connection". What does this mean exactly? Has the phone detected that it can't get out to the wider Internet or did the network fail to allocate an IP address or something else?
Not sure if it matters but this is on a Galaxy Nexus.
Answer
Poor connection may mean that:
- there is either a weak signal from your wifi partner device.
- there is much noise from other systems using the same frequency.
Both mean that many data-packets are lost and have to be retransmitted so your overall throughput goes down.
You can compare this with:
- somebody is speaking not loud enough
- many people are speaking at the same time and it is difficult to understand one person in that noise
If you have interference problems it might help to change the wifi channel/frequency
