My iMac WiFi is extremely slow!!! Help me fix

Hey Stan, that is really good to know. But, can you explain exactly how did you do that so we can do too? Thanks.

I've got it! Just changed the channel on my WIFI Router Settings (Manual - Linksys E1200) to Channel 1 (11 didn't worked). My internet speed on the new iMac seems very similar to iPhone and MacAir (arund 7 Mbps).

Stan can you please give us a step by step process???

I am struggling over here!!!

Thanks for your help in advance!

Well, I just got home all excited and set up my new iMac which is scarce in supply. I set it up and I cannot believe what I'm seeing! It takes ages to open anything!! It's worse than my 6 year old virus ridden Thinkpad that crashed last month. I am on my new Lenovo IdeaPad U510 which I was about to return because there's no human being in North American (although I bought the in home care) ... and it's ripping at warp speed.

This is my first Mac after a lot of pressure from my daughter who got a MacPro for school and it works very fast. But this is ridiculous!!

Talk about routers?! Mine is about 8 years old. Why is my new Lenovo IdeaPad zipping along, 1 foot away from the iMac - both running on WiFi on an 8 year router. I feel like I've returned to the dark ages with my new IMac which cost me $1700 with Applecare. I have 13 days left to return the iMac and aboutthe same to get a refund for my Lenovo - if Apple 1-800 support line doesn't fix this over the phone with a couple of directions - guess which one is going bac? Maybe I keep the Ipad!

This is a very bad first impression for a long term PC user.

And I just had to adapt to Windows 8 - I kinda of like it now after 3 weeks of playing around. It's fast and neat!

So what is the real problem with the iMac

I'm having the same issue. My new iMac is getting spanked by every other wireless device. My wife has a 5year old Macbook, using both in the same room too. I may just call my ISP and see about getting the iMac wired in directly. FYI, I also changed the wireless channel, no difference....

I've been having intermitten wifi issues with new iMac since day 1.

I was messing about with everything yesterday and when i did speedtest i was getting the expected 90mbit down / 9mbit up

Three hours later and my work laptop sat next to my iMac is getting 97mbit down/9up and iMac is getting 34mbit down.

Only thing that happened was iMac went to sleep ...

Think there is something really wrong with either this iMac or OSX ... i'm thinking iMac cos my older 2009 iMac was on same network for years fine ... only until this new one came have i started getting issues.

Got a call with support scheduled

Synagence, was Apple support any help???

Ok so tonight I changed the channel on the router to 8 (changing to ch. 11 didn't do anything). My wireless speed went through the roof!!!! My new iMac now is the fastest device in my house. I don't know why channel 8 is the magic number, but I encourage you to try them ALL!!!

This issue really bothered me and I'm so pleased with my download speeds now!!!!

Yes, I tried 8 and 11 but really they are arbitrary. Just try them starting from 1 until your speed improves. 8 and 11 didn't work for me, but 9 did the trick!

It probably depends somewhat on what other channels around you are being used by other people. If there are too many people on your channel you may have problems.

For my netgear modem there was a "wireless settings" link on the left and you changed the channel there.

How do you change the channel. I know my IP address I just dont know what to do with this. please help fast. I am a photographer and this isnt going to help me!!

If you have a netgear router as I describe above you go to "Wireless settings" in your router configuration page.

What kind of router do you have?

By "ip address" do you mean the address of the router on your home network?

Often it's 192.168.0.1

yes its netgear and yea the number is similar to that one. so how do i go to that page? am i doing this is safari?

Yes in Safari.

U put this in safari:

192.168.0.1 (this may be different, you'd have to check your router user manual)

hit enter, and then login. usually, if you haven't changed it the login is "admin" and password is "password".

then there should be something like "wireless settings" down the left side. and in there somewhere is "channel" which you can change 🙂

You can go to network settings to see what your router address is, if you are uncertain, but its

mostl likely 192.168.0.1.

Wireless Setup, then "Radio" or something similar depending on the specific router.

New router, old router? With Netgear you may have to log into the Netgear site (some of their older routers, the Super G I think was one such - could not be set directly using a Mac, believe it or not. You HAD to go to their support page).
