See an image at http://www.i-tec.it/catalog/images/rptnc.jpg (Most of other available routers have a SMA-RP connector, which is smaller.) Thanks for this and all the other advice... i have a working setup now similar to what is described above. Some issues related to legality are still pending from the local council authorities... but its a small town so shouldnt be a major problem. thanks ashok

Re: [silk] Internet access for senior citizen in special care facility
If you can buy an old WRT54G that can use DD-WRT firmware, signal can be boosted or two of them can be used for repeating forming a kind of mesh if u know someb ody who lives between the two places. I understand WRT54G-L can be used similarly. Tons of info about this on the Net.

Re: [silk] Internet access for senior citizen in special care facility
Hi All, (not sure if I'm allowed to post to the list, so cc to Jace) the right way was mentioned, just get yourself a cheap but good directional Antenna. Forget everything about signal boosters, they are usually crap and will damage the signal and the whole spectrum more than they will help. Use a directional Antenne, this will boost the signal in the sending and the receiving direction and filter the noise which is around you, than 250m should be no problem at all. Regards, Rene PS: Waiting since 16ht of Jan 08 of administrator approval to follow this list, any chance for [EMAIL PROTECTED] ?

[silk] Internet access for senior citizen in special care facility
I have the following scenario : 1) A senior citizen with alzheimers who has been confined to a special care facility. 2) Senior citizen's residence is about 250 metres from the special care facility 3) The senior citizen has a part of her family living in the residence mentioned in (2), there are other parts of the family living in other countries. 4) The family living in other countries want to communicate on a daily basis with the senior citizen, preferably via video chat. So the idea is to provide an EEEpc or similar compact laptop for the senior citizen's room in the special care facility room. For internet access : ADSL is available at the house 250 metres away, so setting up a WiFi access point, with maybe a Wifi signal booster. This would then be accessible from the PC at the special care facility. Does this sound feasible ? Is there a better way of doing this ?
