Need advice with a Netgear RangeMax 240 router and a Belkin Wireless G router/access point

I have a RangeMax 240 router and a Sony laptop in another room about 70 ft away that is getting terrible performance (1MB).

I have been trying to configure a spare Belkin Wireless G router (F5D7230-4) as an access point, but it doesn't seem to be working.

The Netgear router has been set to "G" mode to be compatible with the Belkin router/access point.  The Belkin router/AP is set to access point mode, channel 11 (same as the Netgear router), same SSID, same WEP key.  I can "see" the Belkin router/AP via it's IP address, but as I say, it doesn't seem to be doing anything to help the laptop's performance.

I need some advice.  Will this ever work?  Should I get a Netgear Pre-N Access Point?  Should I get a Netgear Pre-N network card for the laptop?

Thank you.

Al

Is this your house or some type of office building?  Eitherway IMHO 70ft is LONG way inside and you could have alot of interference.  What is your signal strength and quality?

1MB = 8Mbps which is about what you would get if you were using "B" or had a weak "G" connection.

Signal strength is Good.  The speed is usually 1MB, but can range up to 18MB.  The speed varies between 1 and 18 quite a bit, but is usually 1MB i.e. dog slow.

It's a single story house.  There seems to be a lot of interference in this room.  Move the laptop out of it, into an open area 20 ft closer to the router and the speed jumps to 54MB.

Ah, I see one problem "B" vs. "b".  You are using big "B" which means BYTES and I think you mean little "b" which means bits.

There is no way you can get 54MB (megabytes) on a wireless connection as the highest avaliable today is 108 Mb (megabits) which  is only about 13MB (megabytes) in theory.

You must have a big house to have 70ft between the WAP/WRT and your comptuer.  Remember the distances is not what you may walk, but straight line through walls.  You may have issues with waves bouncing off walls and interfering with each other.

If you are truly 70ft away, the max distance for 802.11g is 100-150ft (depending on where you read), however this is NOT the max distance for getting 54Mb.  This is just the max distance for getting a connection good enough to work.

I have also found that most wireless adapters for laptops are not as good as desktops.  I can set my laptop next to my desktop and my desktop gets 100% signal strength and my laptop is only getting 70%.

I'm sorry - my mistake - 1Mb.

No problem, after 20 years big B and little b is one of the most common mistakes I see in networking.  I still use little m (mili) in places where I should use big M (mega) because I get lazy and don't want to press the shift key sometimes.

As for your problem.  It seems to be a distance issue and there are 4 solutions that I can think of:

    1) Move your laptop closer to the WRT.
    2) Move your WRT close to the laptop.
    3) Get high gain attentas for your WRT (if you can find them).
     4) Get a range extender.

There could be some type of  interference between you and the WRT and moving 20ft closer puts the interference out of the way.  A wall, the wireless signal bouncing off of a reflective item (mirror, window, even some walls), or something else.

Have you tried chaning which channel you are using?  If you are using channel 6 (the default on most) try channel 1 or 11.  I can't remember why, but even though there are 11 channels most places I have seen recommend only using 1, 6, or 11.

Changing the channel seemed to improve performance.

Thank you.

There could be somebody else in your area that also has a WRT that could have been causing a bit of interference.

While performance has improved somewhat, it is very inconsistent.  The speed is still varying between 1 and 18Mb, with 1Mb common.

I'd like to get a range extender.  Given that this is an 11N device, would it make sense to get a NETGEAR 54 Mbps Wall-Plugged Wireless Range Extender?  I can't find an 11N range extender.

You may want to look at something like the XE104.  This one has 4 ports, but I am sure I have seen ones like it with a single port.  You would need two of these, one for each end and these go up to 85 Mbps intead of the 54 Mbps that 11g is limited to.  But either one should work.

I doubt if you will find a 11n range extender as these have a longer range than 11g, at least you won't find them yet.  Somebody will build one someday.
