Re: Slow Internet

as long as you are sure on channel one, that is the fist step. Smiley Happy

(if you havent before, you could always run inSSIDer http://www.techspot.com/downloads/5936-inssider.html and scan and see whats around)

 

Some of those other settings.. COULD potentially effect the speed.
Having b/g/n set, can actually THROTTLE back the speed for any connection to b/g speeds, even if its N connecting..

As long as you dont need it, i would change it to N only (or at min, G/N)

 

Again.. coming back to COMPATABILITY.. as long as you dont need it for older devices.. i would recomend changing it over to WPA2 only.

Re: Slow Internet

yes I'm in an apartment.

my channel was set to auto.

it picked 11 but when I scanned there was a couple more 11 in range.

it was saying interference level acceptable.

I switched it anyway to manualy pick 10 which nobody uses and wireless speed is fine now.

seems these modem are not so smart on picking up empty channel

Re: Slow Internet

Yep i will check the settings with bgn, although i think it wont make a difference.

 

Thanks Datalink for telling me that, i never knew, if someone was so determined to do that they would....... although it helped, it didnt really explain the problem.....

 

But thanks nevertheless, I appreciate it! Smiley Very Happy

Re: Slow Internet

I think the basic problem is the wifi performance of the CGN3 compared to your previous modem/router.  There is also the possibility that someone has set up another router nearby which is now causing interference problems.  As Gdkitty indicated, if you load inSSIDer on a wifi laptop you can check for interference from nearby routers.  That will also indicate to you if any other channels are usable, versus the channel that you are currently operating on.  Good wifi performance comes down to signal power and signal to noise ratios, which can also be dependant on the operating mode, ie, b,g,n,or ac.  So, if you find that the CGN3 provides the data rate you require, but doesn't meet your wifi expectations, you probably want to consider a third party router which will provide better control for power, bandwidth and other functions that the CGN3 does not do very well.

Re: Slow Internet

If you load inSSIDer, which is a wifi monitoring application, you can determine what other routers are operating nearby that are causing problems and look for channels which might have better performance for you.

There are 3 non-overlapping 2.4GHz wifi channels: 1, 6, and 11. The others all overlap with 1, 6 or 11.

 

If you're in a large apartment building, honestly, years ago, I reached the conclusion that 2.4GHz is impossible to get working right. 5GHz, if you have hardware that supports it, is the way to go...

Re: Slow Internet

5 definately is the better choice... But not all hardware on the receiving end has it.
You can get a 5ghz wireless card/usb for pretty cheap.. but still not necessarily something that everyone wants to do.

VivienM is correct tho.. while moving slightly off 11 to 10, may get you out of the DIRECT interfearance range, there is still alot of overlap and can cause issues.

Best to look at say ALL the range, and like mentioned.. 1, 6, 11 are the best choices.. and find the least crowded on one of those.

Slow Internet

 Tonight my internet is very slow, I did a speed test 5 times and I am only getting between 2mb/s and 3mb/s download and upload seems ok around 8mb/s to 10mb/s. Usually im 60mb/s+ . Netflix and youtube can not stream anything above 480p and even at that it is constantly buffering. Im on a direct connection to the modem not wifi , the modem is only 2 months old , I have no viruses and also tried resetting my network adapter, resetting the modem and resetting the computer it self and the problem still exist.

Re: Slow Internet

Are you able to go in and check the channel/signal levels on the modem and post them.

If it clears up, but gets bad again, note the time of day, try and get the signal at the good and bad times.

Re: Slow Internet

Internet too slow

 

Hey. So about 2 weeks ago my cable & internet stopped working, and figured out that it was there was a problem with the cable from the green box/ONT to my box outside my house. They replaced the cable from the ONT leading to my box outside with a temporary, air dangling cable. Now everything has been going well untill now. Cable is fine, but my Internet is too slow. Can this due to the temporary cable?
