Hello :)

 

Lets start with some simple questions.

 

1: Does anyone else in your house use your wifi/internet connection?

2: Do any other devices connect to the wifi?

3: What kind of security do you have on your wifi?

 

Once you give us those answers, I think most members will be able to resolve your problem quickly.

I subscribed to 200Mbps.

 

My laptop using ethernet cable got the following:

Download: 245Mbps

Upload: 280Mbps

 

All the while my desktop can get about 25Mbps to 40Mbps but now it jsut become very slow. I wonder is it because of spyware or anything.

And your happy with 40Mbps -- arrrghhh...  That is really slow N speeds..  What does your wireless connection show for its speed?  /2 would be more like the speeds you should see.. From internet.  What is your wireless router?  And what is your wireless card in your laptop?

 

Grab say inssider and look for interference -- possible someone brought up a wireless network on the same channel as you, etc.

40Mbps is the speedtest I did online.

 

Previoulsy, my desktop use Linksys AE300 and it only give me 1 bars signal. I then tried TP-link WN7200ND and I can get 4 bars

 

I do speedtest occassionally and usually I will get 25Mbps ~ 40Mbps speed.

 

Only until last Friday it's speed dropped way below 15Mbps that I start to think is it going to spoil.

 

I went to buy TP-link WDN4800 and initially the speed is even better, did a speed test and I can reach 45Mbps but the next day onwards it start to drop.

 

My wireless connection speed show 144.4Mbps.

 

I'm using ASUS N56 router.

 

I did try to change my internet channel but the speed at most I can get is 20Mbps for download.

I imagine that handphone is your cell.

Well BudMan is pretty much a expert on these things and I agree inSSIDer is a great tool to see how many wireless networks are around you. Check that out and tell us.

Use something like LAN Speed Test and not speedtest.net that only checks internet speed and not necessarily the WLAN.

Actually no, switch to Channel 1 which seems to be the best. InSSIDer shows your signal quality at 30, that's horrible. :no:

 

And for speed issues - which router are you using also? Change the wireless settings from 40Mhz to 20mhz also as using 40 just invitation for trouble.

Yep It's best to use 20Mhz for congested areas due to the secondary channel overlapping with another SSID.

What else is connected to the wireless.  The wireless will slow down to the slowest device connected, doesn't matter if it is downloading anything or sitting idle.  Disconnect all other wireless clients and try the speed test again.

disconnect the "handphone"....it probably is only connected at g speed.

I agree with trying channel 1. It seems to me the less "busy" of all the channels (and with overlapping).

[spoiler]

In general i'll always defer to you and Budman for network stuff but in this case the part about slowing down the whole network is a bit outdated. This hasn't been the case for a while. If a G device is sitting idle on the network it wont slow down everything else. If it's active then it will slow things down but N clients will still be a faster, not full "N" speed as normal however.

 

I have Dell Latitude XT (G only) along with my Thinkpad (AGN). I've recently updated it to Windows 7 as I mentioned (in other posts) and downloading tons of updates plus downloading ISOs on it didn't cripple the 2.4Ghz network as it usually does. Obviously 5Ghz is not affected.

Ahh sweet, your link score jumped to 77/100 now which is much better. Speeds still suck though, care to post your advanced wireless settings?

 

Also it seems your desktop is 5Ghz so why aren't you connected to that one?

 

Oh and besides speedtest - downloading a file from say Microsoft.com or somewhere fast, does that work good?

I tried my 5GHz before, signal strength 'Fair' and the speed is even slower.

 

I'm using ASUS N56 router.

those speeds are really slow for even g though.  something is def up with the wireless. Have you tried resetting the router to see if it makes a difference.  something sure isn't right.

How about you kill off N, as in set your router to G ONLY mode and see if that makes a difference.

- Legacy

 

Currently I'm using 'Auto'

I didn't upgrade my firmware as previously I called up ASUS and asked about it, the technician guy told me not to upgrade.
