Hi All,
I have Sterlite modem HUAWEI WA1003A.I am using BSNL UL750 plan.My laptop works perfactly inside the room where the modem is kept but does not when i move out of that room. Even when I sit just 2 meter away from modem acroos the wall in next room it can not work.

Should I upgrade the modem? Please suggest.

Many Thanks in advance!
Rajive.

Position the modem at a greater height , if possible.
WIFI signals need "Line of Sight'
Position near the window .
use an Aluminium foil in the back of the antenna .
as a reflector.
Feed back.

Change of modem is the last resort. Try essbebe's suggestions first.

Thanks. I tried keepin modem 2 feet above and also used an aluminium foil behind antenna but the result is same.
I also see in general the siganl strenght low with only two signal lines.

( for quicker connection ).

^ These suggestions are good but not going to help much, because if wi-fi is working iside the room/connection OK/signal = excellent, and outside room = everything bad

then the problem is not with setup, drivers, etc.

The signal is weak or the walls too thick, etc.

Essbebe, your suggestion of keeping wi-fi modem near window will help. But the author must sit in the adjecent room.

Please find attached screen shots.
DO I need to first make wireless connection secured?
I did find how to do it in the url providedby u.

For now the wireless gets connected as soon as I switch on modem. Then I connect by using bsnl connection(similar to when LAN wire is connected to laptop).

Feedback to post No 5 awaited.

You can also try to change the channel No.
from 6 to 11 or 11 to 6 .

If the Antenna can be positioned in Horizontal mode
( or the modem kept in the table , such that the antenna
is parallel to ground , then rotate the unit for max signal in other room.
This changes the radiation pattern from a circle ( 360 degrees)
to figure of eight . Say North/ South or East Wes
.
The screen shots are not seen. Use only Jpg format and use annexures here.

Quote:

The range of a home Wi-Fi LAN depends on the wireless

access point (WAP) or wireless router being used. Factors

that determine a particular WAP or wireless router's range

are:

* the specific 802.11 protocol employed
* the overall strength of the device transmitter
* the nature of obstructions and interference in the

surrounding area

A general rule of thumb in home networking says that

802.11b and 802.11g WAPs and routers support a range of up

to 150 feet (46 m) indoors and 300 feet (92 m) outdoors.

Another rule of thumb holds that the effective range of

802.11a is approximately one-third that of 802.11b/g.

Both of these rough estimates fall on the high end of the

range seen in practice. Obstructions in home such as brick

walls and metal frames or siding greatly can reduce the

range of a Wi-Fi LAN by 25% or more. Because 802.11a

employs a higher signalling frequency than 802.11b/g,

802.11a is most susceptible to obstructions. Interference

from microwave ovens and other equipment also affects

range. 802.11b and 802.11g are both susceptible to

these
