Does this (http://www.oemexpress.com/Itemdesc.asp?CartId={57CCA2E2-58C5-44BF-8095-887CD1794B31}&ic=NETAIR%2DASB100A&Tp=) allow me to reach a signal through my PCI Wireless 802.11 g card that could not normally reached?
The more dbi, the better. I live in a house with lots of concrete walls and with a £70 8 dbi signal booster I barely got 2 bars of signal strength. How many walls will the signal need to pass through?, what composition are they (i.e., brick, drywall etc)? Also check if there are any wires within those walls if possible as they can disrupt a wireless signal too. Also, what router are you using?, too achieve the best possible signal you may want to consider a new router with MIMO technology as these are designed to broadcast the signal through walls. I tried 4, yes 4 different MIMO routers and had problems setting all of them up, in the end I returned them all. It's a bit hit and miss with them as the technology is relatively new, some people have no problems setting them up and they run like a dream, others like me waste days trying to get them to work. In the end I gave up and decided to cable my house, this turned out best for me as I could get the maximum speed my modem can handle too the other computer without loss of signal and my network is secure from wireless internet piggy backers. If you really want a good booster then an external one will have the best dbi available, there available off eBay and have dbi's of 16+. Cheers.
There are 3 [concrete] walls in the way. Another computer [7-8 metres from the spot of the computer I want the internet on] receives the signal at a strength of 10-30% [usually between 15-20%]. I am thinking of purchasing a 10 dBi anternna (http://www.oemexpress.com/Itemdesc.asp?CartId={57CCA2E2-58C5-44BF-8095-887CD1794B31}&ic=NETAIR%2DASB100A&Tp=) to be able to reach that spot. I am assuming that this antenna connects to my [future] PCI Wireless 802.11 g card [by taking the place of the small 2 dBi antenna that comes with it in the box]. I've read that a 6 dBi antenna increases the signal strength by 50% (multiplies it by 1.5)...does that mean that my 10 dBi [with its additional 8 dBi as compared to the 4 of the 6 dBi antenna] will increase the signal by 100% (multiply it by 2.0)?
The signal booster will either connect in place of the small antenna that comes with the card or via USB. Not sure how that calculation work lol but the more dbi the better, concrete poses a problem so you may want to consider one of those MIMO routers to make the signal better as the better the signal strength the better the speed will be.
D-Link's USB Device (DWL-G122) has a 10-30% [usually between 15-20%] signal 7-8 metres from where I want to reach it. Will the AWLH5025 MIMO XR™ 802.11g Wireless PCI Adapter (http://www.airlink101.com/products/awlh5025.html or http://www.oemexpress.com/Itemdesc....DE-9E12-B83117B681EC}&ic=NETAIR-AWLH5025&Tp=) fulfill my "dreams" of reaching the signal? I have looked it up on google and, I am not sure if this is correct, but, I read that the DWL-G122 device I currently have reaches up to 90 feet of distance while this AWLH5025 MIMO XR™ 802.11g Wireless PCI Adapter can reach up to 2550 feet of wireless coverage. Is this information true? If so, then, am I guaranteed to get the signal with this? THE ROUTER IS A NORMAL 54 MBPS ROUTER, AND, CHANGING IT IS NOT AN OPTION. If someone can confirm that this should work for me, I will be very happy!
If your getting a signal with your current setup then this should work and give you a little more signal strength. D-links products are nice,Iv'e used quite a few d-link networking products in the past and theyv'e never let me down.
The D-Link DOES NOT work! It works from a spot 7-8 metres from where I want it to work. In other words, I want this Airlink product to have the same signal strength with an additional 7-8 metres of signal coverage. In even simpler words, I want to get the same signal strength as I would get with the D-link but located 7-8 metres even farther [than the D-link] to the router.
I see, well the d-link should work but i guess the walls and such that are in the way are prroving to be a bigger problem. Try the Airlink but inless it's dba is considerably higher than the d-links i doubt it's going to work. It's just a question of getting devices with a very high dba now and seeing what works.
The basic problem you have is the signal drop off due to the mix of range and obstacles. The best way around this is to use a wireless repeater rather than a high gain antenna. This takes the signal from both ends and then re-generates it so that any signal loss is retrieved before retransmission. This does however introduce a slight loss of throughput on the link, basically a reduction in bandwidth, as the transmitted data has to be received, and retransmitted each way. This is not going to be too significant on a 54MB link. Something like this would work, you just need to find it locally, and then place it in a convenient place half way between the networked components. http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=487774
