1) 鋁箔包把天線蓋起來就好了啦
測試過了，不行
2) 我的機器型號是edimax br-6228ns
3) 關於Wifi訊號對人體有沒有害，以及那麼多基地台、手機訊號等等問題，並不是如同各位網友所說那樣可以直接類推比較的。（歡迎大家認真討論，口水閒話就免了）
我查了以下幾篇研究：
a) UK Power Watch：
http://www.powerwatch.org.uk/rf/wifi.asp
b) 2007/12 Updated Memorandum on WiFi Research
http://www.powerwatch.org.uk/pdfs/20080425_wifi_memorandum.pdf
幾個摘要如下：
a. There has been plenty of media coverage of WiFi and the potential dangers in 2007. There is a lot of misunderstanding and misrepresentation of evidence being thrown into the mix, and it is becoming very hard to follow the strands of a) what the exposure levels are, b) what the evidence is actually saying, and c) what other aspects need to be considered on WiFi.
b. Last in 2008 a new website(http://www.wifiinschools.org.uk/) appeared providing a rational and well supported scientific argument for the validity in precaution of the use of WiFi in primary and secondary schools.
c. Therefore 20 minutes on a mobile phone running at typical power levels would be equivalent to about 16 hours in a classroom with 20 wLAN PCs, approximately eight standard school days.
d. However, these figures are assuming that it is cumulative absorbed power that is being implicated in RF research, and that then implies a linear dose-response relationship model. From the evidence that has found a risk, this seems unlikely to be the case. Peak signal strength received may also be important, and people using WiFi enabled laptops would regularly be exposed to electric fields of 2 to 3 V/m. Whilst this is far below ICNIRP, it is far above the levels where adverse health effects are being reported (~0.05 V/m).(這段我看不太懂)
e.Firstly, typical exposure from a phone in use is likely to be far higher than from a typical WiFi laptop or access point due to the different in proximity to the device in question. So whilst, again, there is research showing that there may be a risk, this may not be relevant.
f. To study secondary school children in the 12 -15 year-old age-range as we have reports that this group is more affected than primary school children . This may be due to their long
er exposure to environmental agents.
另外，根據 http://wifiinschools.org.uk/22.html裡有提到，Papers finding biological or adverse health effects of Wi-Fi signals, Wi-Fi-enabled devices or Wi-Fi frequencies (2.4 or 5 GHz).
我無電子相關背景，看上述文章也是大半看不懂，因此只摘要英文，不敢隨便翻譯。歡迎高手協助釐清。謝謝~

而EMF對人體可能的影響：
...
short-term, immediate health effects such as stimulation of peripheral nerves and muscles, shocks and burns caused by touching conducting objects, and elevated tissue temperatures resulting from absorption of energy during exposure to EMF”
ICNIRP Guidelines, April 1998, v.74-4, p.496
另外，關於手機和Wifi的影響性與相關度，摘要於下：http://www.powerwatch.org.uk/rf/wifi.asp
Mobile Telecommunication systems (CDMA, GSM and 3G) are both closer in frequency and are also digitally pulsed information carrying signals - these are sufficiently close to WiFi that the research into phones and their base stations may be applicable to exposure from WiFi.
（簡譯：手機訊號與wifi的訊號與頻率是相近的，因此相關的研究也許可以適用於wifi)
Firstly, typical exposure from a phone in use is likely to be far higher than from a typical WiFi laptop or access point due to the different in proximity to the device in question. So whilst, again, there is research showing that there may be a risk[2][3], this may not be relevant.
However, signal strength from a mobile phone base station where it reaches the ground (approximately 70 to 100 metres from the base station) is typically between 0.5 and 1.5 V/m, exactly the same as we measured in a WiFi classroom in a school in Norwich, and the same as found in the above calculations, and seems therefore to be very relevant. A quick survey of the literature looking very specifically into mobile phone base station epidemiology finds some statistically significant health effects[4][5][6][7][8][9][10][11][12]. Many of these are summarised, with helpful graphs, etc, in our library article "Radiofrequency EMFs and health risks". There is, in fact, very little research looking at base stations that has failed to find an effect. Also interesting is that many of the effects in the papers above (non-cancer effects) are those being reported in the anecdotal evidence from WiFi exposure.
（已有研究顯示基地台對健康會造成影響，而基地台的訊號強度等同於wifi 教室內的強度。)
In essence then, there is sufficient evidence to warrant some degree of precaution regarding WiFi until research has been done very specifically into its effects. With dLAN systems and ordinary CAT5/6 wired networks offering better stability, bandwidth and security, there is simply no need for most homes, organisations and schools to switch to wireless networks, apart from the savings of the slight inconvenience in cables.
(在有更進一步對Wifi的研究之前，對Wifi採取預防措施是有足夠證據的)
