upgraded to up to 60Mbs but can not get more than 25Mbs

I have upgraded my internet broadband to be 60 Mbs instead of 30 Mbs , but unfortunately my download speed can not go more than 23 Mbs when using wireless, if i connect the supper hub ( VMDG-480) to the computer using Ethernet cable , i am able to get 62 Mbs..
my dell computer has dell wireless 1397 wlan mini-card... i am not sure if it supports N wireless
what is the solution in this case.. should i change my wireless card ...

I'd look at a pair of homeplugs instead, they give a more reliable connection than wireless by using your electrical ring main. There are plenty here to have a look through. Just plug one into a mains socket by your router and run an ethernet cable between the two, then plug one into a mains socket by your PC and run an ethernet cable between the two and your PC will then have a hardwired connection.

Thanks for the reply,
so you mean to say using TP-Link is far better than buying wireless card that supports N wireless..
is using TP-Link giving a good speed as using Ethernet cable..

I'm not sure if they'll give quite as good performance as a direct ethernet cable but they'll definitely give you a more reliable connection than wireless.

Hi
Thanks Sandeep P, and much more thanks to Boozad....
I have just bought Power-line 200 Home Network Adapters from on networks , they are the best solution, it's better than upgrading my wireless card to N-network
after installing them i tested the speed using speedtest.net and internet-speedtest.net. Now i am able to get around 60Mbs and upload nearly 3Mbs.
i was at PC world this morning and the guy who is in the store advised me to use particularly this type (Power-line 200 Home Network Adapters from on networks) as he has been using them at home and giving him good internet speed and the price was cheap £20...
so even if i upgraded my wireless net work card, i am sure i will not be able to get this speed using power line home adapters...
results for the speed tests attached

Glad they worked out well for you mate. Enjoy your new speeds!

Thanks mate...
you really pointed me to a very good thing... power line home plug adapter.. they;re very good hardware.. so far i am able to get the same speed as by using Ethernet cable... one thing is ping is different ... no effect reliability much i guess..

The signal won't travel outside the wiring, your ring main is a closed loop effectively from your consumer unit to the last plug socket in the ring main. There's no chance of anybody who's not connected directly to your router (or your electricity mains circuit, in which case I'd be worried before sending ethernet signals down it!) getting access to your signal. I'm still a bit confused as to how signal is sent down mains cable as mains usually creates 'noise' across the signal, but it works well and I just take them at that value. I suppose I could look into it and probably will one day.

EDIT: Actually, and I could be wrong here, but I think that homeplugs are paired. For example, I don't think you can plug into one adaptor from your router and draw that signal from two other adaptors simultaneously. I'd have to verify that though.
