• At -43 you have a good strong signal.
• You are using 802.11n, capable of speeds as high as 600 Mbits/sec on a clear channel, close by, with no interference.
• Channel 11 is in the crowded 2.4 GHz band, and that is likely where all your neighbors are as well. Also baby monitors, Microwave ovens, BlueTooth devices, and some cordless phones.
• A transmit rate of 130 indicates a fair amount of your data are getting through (otherwise it would slow down more for better reliability)
The Bad news: there are only THREE Clear Channels in that band -- fewer if you use 802.11n. So you are likely talking on the same channel as at least one of your neighbors.
One way to get better connectivity and better speed is to replace your Router or add on with a dual-Band Router, which would also get you 8 to 12 more channels in the 5 GHz band, and better speeds.
You should make sure that the Network you want to join is FIRST in list here, and use the Minus button to remove extraneous networks:
Thank you for the reply. My router is anyway up for an upgrade; guess I should do that and see. I have a few years old Airport Extreme currently! I am looking at one of these: http://amzn.com/B00DB9WCR6 or http://amzn.com/B00EXK14S0. Which one would you recommend? Or is there another model that may be even better?
I just bought an Airport Extreme through the Apple refurb store for US$169. plus tax.
My speed increased 5 fold because I could move to the high band and use the full 802.11n. It is running at 300 Mbits/sec in the 5Ghz band, where you are getting 130 in the 2.4GHz band.
I finally bought a new Airport Extreme 802.11ac and replaced my old one. With the new design and antenna positions I was expecting the overall signal strength to be stronger and range to be better. But on the contrary everything seems to have deteriorated drastically. Here is the new WiFi
Here are the signal details when my MBP is 3 feet from the AE:
Here are the singal details when my MBP us 15 feet from the AE:
What may be the issue? Do I have a defective piece?
thanks for your help,
RSSI of -74 at that range (unless the signal is shooting through a solid brick wall) is surprisingly bad signal strength.
My Mac Pro 42lb tower, from inside an aluminum enclosure, 15 feet from the Base Station through two plaster walls backed by grounded wire lath gives a receive signal strength of -58, far higher (closer to zero are stronger) than your MacBook Pro.
I think you (alone on this thread) should have your MacBook checked for a disconnected or damaged antenna.
I had a similar issue, and it took awhile to figure it out. I believe that this has to do with Power Nap and a conflict between wifi and a bloothooth pref setting.
Here is what I did to resolve the issue:
1. Disable Power Nap in the Energy Saver prefs
2. If you have a plist editor delete the entry for LastA2DPDevice in the com.apple.Bluetooth.plist
To make this step easier you can use the following command in the Teminal.
sudo defaults delete /Library/Preferences/com.apple.Bluetooth LastA2DPDevice
3. Restart your Mac
4. Re-enable Power Nap in the Energy Saver prefs
