Are you sure it's "your" hot spot? Do you own it or are you simply
trying to get a free internet connection from the local coffee shop?
Coffee shops will often try to limit the range of their wireless
access points to only cover their customers and not service the entire
neighborhood. I recently worked on a system to measure the distance
between the access point (via propogation delay) and the client radio
and thereby restrict the connection range.

Well, the Acer uses the Realtek 8180 series for wireless. I think
(not sure) that it's integrated on the motherboard and cannot easily
be replaced.

The cheapest? Open the laptop and find the antenna. It might be just
a trace on the motherboard. Cut the trace and attach a small pigtail
using RG-188a/u TFE coax cable. The other end of the cable would go
to an SMA connector. Keep the pigtail as short as possible and just
long enough to exit the laptop at some convenient point. Attach an
SMA to N adapter, some LMR-400 coax, to a suitable external antenna.
If that it too much work, it is possible to add a 2nd radio to the
laptop. Disable the internal wireless (in software). Plug in an
additional PCMCIA or USB 802.11b radio. Setup an external antenna.
