Hi guys. I built a new desktop, and now I need internet. I can't use wired connection for reasons. Right now I'm using a TEW-645UB Trendnet adapter. It works but it only picks up a few bars, and it's laggy in game. I'm using my desktop for gaming.
Is there a better adapter out there?



Answer
That Trednet model is a decent High Power Wireless N Adapter with full backwards support for IEEE 802.11b/g, and support for latest IEEE 802.11n Draft standard. It is likely that the position of the router is causing thee problem.

I would certainly try and improve things by repositioning the router [I have suggested several things below] before rushing out to buy a new adapter that may or may not improve your signal.

It would obviously have helped if you had given details on the make and model of the router and whether it supports draft n wifi standard and if it has "Dual Band" support for broadcasting simultaneously on both 2.4GHz and 5GHz frequency bands.

There are several things you can do do try and boost signal strength; To start with the basic rule is to position the router as high as possible and there are as few walls as possible between it and the PC.

Things you can do to improve signal strength

1] Try changing the broadcast channel from the wireless setup interface for your router/modem.You can normally access this by typing "http://192.168.0.1/" into your browsers search bar and then look for the wireless settings menu.
You don't say if your router can use the 5GHz frequency or just the 2.4GHz. The best channels in the 2.5GHz spectrum are 1,6, 11, or 13 as they have less overlap with the other channels.

There is a useful article here about how to get the best performance by selecting the best channel.: http://www.howtogeek.com/howto/21132/cha…

If you have an android smarthphone, or a friend does, then install the Wifi Analyzer app free from android market and use it to scan for the best channel and change your routers broadcast channel accordingly. This app will also show you all the wifi signals in range that your neighbours are using, so you can select a different channel to them, making a stronger signal for you. https://market.android.com/details?id=co…


2] You can use a tool like Nirsofts totally free WirelessNet View to look at all the local wireless signals that are within range and may be competing with your own router and interfering with reception. from here: http://www.nirsoft.net/utils/wireless_ne…

3] You can buy a Wi-Fi booster like D-Link 645 Smartbeam, here: http://www.amazon.co.uk/D-Link-DIR-645-W…
Devices such as these can actually boost the wifi signal by using multiple beams that bounce of the walls and are intelligently directed toward whatever device [smarhphone, laptop, tablet] you are using on wifi.

4] If your using the 2.4GHz frequency and not the 5GHz then other devices that use this frequency band can also interfere with your reception [eg baby monitors and microwave ovens use 2.4GHz]. Try and make sure that none of these devices are situated between your router and your PC

How do I connect to a Modem that is in another room?

I have a PC that did not come with any wireless abilities. I bought a wireless adapter so that i can connect to the internet but i feel as if its running out of days and that i would be much better off just having a cable running from the modem directly, but its in another room. Like on the other side of the house. I have a laptop that doesn't really get into as much problems with the connection as my PC does which makes me think its the adapter. Also I found out thtat the one PC that is connected directly to the modem gets great internet. How can i get better internet without having to change much. Is it my possible outdated adapter? How could I resolve this.
Some of these observations may be obvious and my issue might be minor to some but i could use some help and advice.
Thanks for your time :]



Answer
To answer your titled question first. Apart from wifi you can still connect via hard wired ethernet cable if the router/modem is an another room, if you don't mind the cable clutter. You can buy 25metre even 30metre plus ethernet cables on amazon for under £10.

As regards, problems with wifi reception and reduced network speeds there are several things you can do to try and improve performance. You don't give any details on your hardware or network configuration, so general advice will have to do:

To start with the basic rule is to position the router/modem as high and as centrally as possible in your house.

1] Try changing the broadcast channel from the wireless setup interface for your router/modem.You can normally access this by typing "http://192.168.0.1/" into your browsers search bar and then look for the wireless settings menu.
