The pay few days I've had terribly unreliable internet via wifi. Packet loss is near 100%. Anything streaming or gaming is horrible.
My download speed over wifi is about 4Mbps, upload is... 0.7Mbps. Comcast said signal was good but packet loss was 100% when they tried it. Here's what I've tried: New router New modem New modem & router combo Tried changing channels with the router Disable and re-enable WMM under QoS Replaced all coax wires for devices I hooked up a laptop to the router, speeds were like 60 Mbps, where they should be. Any idea what to do? Is it interference? Any way to tell if something bestbuy is screwing it up? I do know that when it rains the internet gets finicky, so I've asked Comcast to come out and inspect the connections outside. |

If you've tried a new router and modem that seems whack. Especially considering that going wired to the router works fine. I don't see how the outside wiring would affect it unless the wired connection was bad as well.
I know that my wifi sucked balls until I disabled WMM. My download speed doubled from an average of 30-40Mbps to 60-80Mbps. Changing from auto channel select is also recommended but that didn't do anything for me. If you do this run a speedtest after every change. I found that some channels were significantly worse than others. |

You said you changed your router? Did you try changing the wireless channel(s?) did you get a new home phone recently? What is your average signal strength? Do you have a phone or tablet where the problem is the same?
Since you have Comcast and likely have their newer modem, by default they enable wifi for 'public' use. My bet is your channel on your router is interfering with something, maybe a close neighbor. Most routers default to channel 6 and most never change that, play around with your channel options. ETA, if you haven't swapped out routers that's your next step as the amplifier or something in the circuit board is bad. If your router is DD-WRT compatible, try that. |

Get an 802.11an router. If you are currently using an 802.11g router it is probably getting its signal raped by your neighbors.
It wasn't a big problem five years ago when some (old) people still didn't use wireless. Now everyone has two or three wifi signals per house. There are only THREE channels that don't overlap. So a lot of people now seem to need a more powerful signal that can filter interference better, or to switch to 802.11a. An 802.11an router can do all of the above. Spend at least a hundred dollars to get a decent one. |

I had the exact same issues and I finally traced it to the airwaves in my house being overloaded by all the neighbors' wifi.
I can see 10 other wifi networks. I tried changing channels, but they're all jammed. If you have an android of some sort, download an app called wifi analyzer. It will tell you the channel of all the networks. You'll want to pick from channels 1, 6, or 11, whichever is least crowded. If that doesn't help, its likely you'll need to upgrade to a dual band wifi router as well as cards or usb sticks for all your devices to work on 5 ghz. That is what I had to do. I often got 0.5 to 2 mbps before. Now I get 60 mbps. If you're nowhere near any other wifi networks, it might be other things interfering. Baby monitors, cordless phones, microwaves, are also common things that interfere with regular wifi. |
