This past Tuesday I installed the new N router. Also, we upgraded to FiOS Quantum 75/35 (previously 15/5). That was activated the following day. I can't complain about the internet speed to our pc since it's wired. Speed tests showed we were getting what was advertised. 🙂
For the wifi, I can't figured out for the life of me what's causing our devices (e.g., our Nexus 7 tablets) to have a link speeds of 65Mbps one minute and then drop down to 5 or even 1. The same situation was happening with my HTC Incredible II phone, but I think that connection was tapping out at 54Mbps. The bottom would just drop out of the signal for some reason. Other times we couldn't even connect back in. The devices would say they're not in range even when they were in front of the router. Not sure if I fubarred the router install or what? I just swapped out the current Fios router for this new one. Pretty straightforward. At first, I logged into the router software with the defaults, but then I changed the the username, pswd, SSID, etc. to match what I used previously. I thought it was working fine the night of the install but not so much after Fios got bumped up in speed the following day. Maybe just a co-inky-dink?
I know you never get the same speeds compared to a wired pc but this seems worse (wifi-wise) than before the new router came along. I've read that the 'N' routers can be finicky to set-up to run properly. Maybe a setting or two is off?
I don't know if the fact that my son's netbook's wifi card is only b/g compatible would slow our network down? At this point I'm grasping at straws! I talked with tech support last night for 40 mins to no avail. I got the usual story about wireless devices running slower than wired ones, that these smaller devices aren't capable to maintaining higher speeds (which I'm not sure I agree with 100%), the more active devices you have slows down your network, etc, etc. I get all that. But something is going on or actually, it's not. LOL!
Why I don't agree with the above statement I mentioned is because I have my tablet at work now and the wifi speed is 54Mbps and it's constant. So it seems to have no problems with this speed, unlike what I was told over the phone.
Let me know if I can provide any further technical details that'll make it easier to help diagnose our wifi issues.
Thanks for listening to me whine ,
try logging back into the router, go to wireless>advanced wireless and do N mode only (under advanced options or other options) and see if the speed is better or more stable. B/G devices ARE supposed to slow down the other ones from what I remember, so you might be right.
Also while you're in there make sure that you are set to WPA 2 [AES]
the TKIP setting will slow you down to the 65 mark and AES will let you go upto the 70, 80, 90 and 100 mark.
Also experiment with channel 1, 6 and 11 and tell us which performs better for you.
Thanks for the help, Hubrisnxs.
Here's an update since I got home:
Nexus7 (N7) took a min or so to connect to wifi when I got home. When it did, speed said 65Mbps. So I ran speedtest.net and got 27/20. Shortly after that I tried again but it was hesitating. I checked the speed and it was down to 5Mbps. Brought it upstairs to router and pc, and eventually it was back to 65. Ran speed test a few more times with similar results. I did notice that the connection would intermittently come and go. Not sure why. Looking at the wifi section on my N7, it says our network is out of range and the N7 is 2' from the router. Every now and then my network will go to the top of the list and it'll say it's obtaining ip address, then secured with wpa/wpa2 psk and it's locked in. So I hit the connect button and it's out of range again. Of course, while I was typing it decided to connect after 10-15 mins of trying/nothing. Says, signal strength excellent, 52 Mbps. Spoke too soon. It's off again. Crap! Back on again but speed was 19, now 5.
I did check router settings and this is what I have:
Performance mode ('n')
Maybe I'll try channel 11 next.....
Just for the heck of it, here is the results from verizon speed test on our pc (wired of course):

IIRC, this is not a dual-band router. That means that if there is another device that cannot do N, it will shift to G and stay there.
also, I think this is a 2.4Ghz router. If you have wireless phones or other devices, they will interfere.
I would not waste my time with it. I would go purchase a decent dual-band router and use it instead. There are instructions around on how to set up a 2nd router.
Well, things have gotten better since my last post. The tech support person, who was very nice, did whatever she could (for an hour) from Verizon's end to help me out. She rebooted my router and switched channels but doesn't that have the same affect when I do it? I don't know. She's sending out a new router just in case, even though she doubts that the router is faulty. Since I'm getting great wired speed, the router seems fine. I tried downloading the pc optimizer software from the Verizon site, but every time I did Trend Micro said it detected a virus and removed the file.
I did make some changes to my environment that "seemed" to help. I relocated the router more out in the open and not behind the flat panel tv, and spread the antennae out. Also, disconnected the wifi devices I don't really need operating while at home, like our smart phones. Since we have tablets there's no need to use the phones to email/web surf, etc. So, fewer devices mean more bandwidth to share. I also turned off our Wii's wifi. Don't use it. Plus, it only uses the b/g networks. So, this may have been one reason for the slow down. Also, my son's netbook is the same way. However, I did just order from Dell, a Cisco wireless-N USB adapter. Hopefully that will work as planned, and we'll be able to use the netbook again. So at most we'll have five devices hooked up instead of nine.
I was thinking about our cordless phones last night and looked them up on the web. They are Uniden models and use the wifi-friendly range of 1.9GHz. I may have to look into a 2nd router.
Installed the new Cisco Wireless-n USB adapter last night, and my son's netbook is back in business. Chuggs along nicely now. At least it shouldn't be dragging our network down.
I also installed the inSSIDer 2.1 software on the netbook. Looks like fewer connections on Ch 11. I was on 6. According to the graph, there's less overlap on 11. I'll see how the new channel works for now. Also, RSSI is the interference, right? Mine is hovering in the -30s and the next closest is in the mid -60s. I read it's good to have some separation from someone else on the same channel. But it looks like the closest neighbor is doubling up. Its channel is 11+7. I assume low RSSI numbers are good? Closest to zero, I mean. Lots to learn about this stuff.
RSSI is Received Signal Strength Indication
As inSSIDer reports it as a negative number, the lowest, or closest to zero, is best.
