@logo1234,
STOP! DON'T BUY ANYTHING YET!
OK so you have a Motorola Modem. Is it the SB6100 or SB6120? If not then you're not making the most of your connection as your modem can't handle the bandwidth (i.e. isn't DOCSIS 3.0) That would be the first thing to fix.
I had a look round at the E2000, and it apparently has a reputation for severe wireless drop-off in as little as 10'. :$
THings I think you should try, report back here, before you spend any money:
1) Wi-Fi speeds of 20-25Mbps are consistent with your international bandwidth of 30Mbps, if indeed you are testing on international sites
2) Go to starhub utilities page.
http://utilities.starhub.com/conexon/en ... tFrame.jsp
3) Verify in the box at the top it says Maxonline Ultimate (this saves you having to call them again!) Click Continue, accept the javascript popup, scroll down and run the download test ON A WIRED CONNECTION
4) repeat step 3 ON A WIRELESS CONNECTION...that way we have a baseline for comparison between your wired and wireless throughput.
5) If those figures are the same, and your modem is DOCSIS 3.0, then nothing to do, you are at the mercy of Starhub. BUt I would expect you to be hitting 80Mbps on your wired connection at least, even with contention ratio.
Report back with your results so we can help further.
If, from the above tests, your wireless is significantly less than wired throughput, then there are things you can try first. You are going to need a wired connection as you might lose wifi access during some of these setting changes, and you need the wired connection to change settings back
1) Go to
http://tools.meraki.com/stumbler and run it (web based wifi sniffer)
2) Look at the channels and number of Access Points on each channel...are you sharing chanel 11 with tons of your neighbours? IN which case, go into router settings and change your channel to something that isn't being used/least used by neighbours.
3) Check router settings for 2.4Ghz or 5Ghz. If all of your devices (laptop/tablet etc) are 5Ghz compatible, disable 2.4Ghz as you might find better throughput at that frequency.
4) Check router settings for channel at wireless b/g/-n. If you are outputting "auto" or b/g/n together, then (assuming all devices are N compatible), switch to N only.
5) If you are running 2.4Ghz wifi, then switch Channel Width to 20Mhz (not 40Mhz or 20/40Mhz). This will narrow your channel width and reduce interference from other devices and networks. But only do this if you have done (1) & (2) above, otherwise its pointless.
Let me know when you have tried all that, see where we get to
