I didn't look at those links right [too early in the AM (sleep working)]; my BAD! Let's clear this up: The size of the antenna is not the only conseration for reception. You are going to be addressing driver protocol issues (since 802.11G/B/N are actually implemented in non-standard varients in small ways depending on the manufacturer) and often link up better to their own kind or AP's and cards known to function well together. Another consideration is going to be AP beacon strength. I have an older card that does not connect with anything but a Netgear 802.11B AP. You possibly are misunderstanding the difference between the term AP and standalone cards? Almost any Wifi card can become an AP depending on how it is intialized. This AP: ENCORE ENRXWI-G 802.11b/g Wireless LAN Extender up to 54MbpsIs someone off-brand and is actually an AP (access point) that can be "bridged together" to span wide areas that cannot meet coverage themselves, so that users can "roam" between AP's and authenticate to one source. This Encore is probably not a very reliable unit, but I didn't do the typical due diligence RESEARCH (Google it) to verify what people are saying, etc. I imagine it has protocol issues with some varieties of cards, like the difference in DLink and Netgear in the early days (13 years ago). Also, it would not be a connection solution for your sisters system, since it's not going to provide a local connection or adapter, which the system can use. Its strictly standalone. The second link is: D-Link DWA-125 IEEE 802.3/3u, IEEE 802.11g, IEEE802.11n Draft 2 USB 2.0 Wireless Adapter Up to 150Mbps Wireless Data RatesThis is a USB adapter 2.0 connected device for computers that do not have a card slot either PCMCIA or internally. Wireless 2.0 USB devices function significantly faster than Wireless data throughput, (firewire...?) so that is not going to be a factor (if you don't have a slot or open bay); however if her onboard USB driver in the OS (old XP?) (and in really ancient hardware bios firmware does) not operate at USB 2.0 you will have connection issues. *Be sure your current issues are not also related to a USB 2.0 driver issue, an IRQ conflict, or a short in the cabling, before you assume new hardware will fix it. The first step toward verifying this link is to patch your system to current recommended versions (if Windows, MAC or Linux) and update both the driver and device fiirmware if a flash version is available (often not).* If your current AP or "router" is perhaps not 802.11g, your card "adapter' is not going to be able to connect via those speeds/stability. I believe that Dlink's DWA-125 IEEE rates 802.3/3u provides for integration with the USB stack or driver/LAN layer, but I would have to read the fufll specifications.
