Simply put, no. Wireless B is more reliable at longer distances. Wireless G gets slower the farther away from the router you are, to the point where the signal is unusable.

Can 2 wireless routers be connected wirelessly together no cable

In short, the answer is yes.

However both routers need to support what is knows as WDS (Wireless distributed Network)
This allows multiple routers to connect together to extend the signal of a single wireless network.

The steps change from one router to another, but in general you will need to log into one routers web interface (usually by first plugging a hard wire into the router then into your computer. Then open a web browser and put or in the address bar)

Default username / passwords are usually admin / admin unless you have changed them

Next goto the wireless section and set this first router up with the wireless name and security you wish it to have.

Repeat this on the second router, but this time you will need to goto wireless and look for an option that says "Enable WDS"
Some router have a "Survey" option, this will bring up the wireless network the router can see and allow you to easily select which network you want to connect this router to.
The one big step is to make sure the second router is setup the same as the first, you will need to make sure it is named the EXACT same, and also is using the same wireless password as the first.

In some cases you may want to disable DHCP on the second router, but this may not be necessary, so testing with DHCP on may be your first options.

Test the connection while the routers on are the same floor to start, this will save time going up and down stairs if settings need adjusted.

Also keep in mind wireless signal goes outwards from an antenna, so having one upstairs and one downstairs you may still see low signals, In some cases you can adjust one antenna on each router to lay flat instead of pointing up in the air. This should only be done on one antenna on each router if signal is too weak. It does not always help.

Hope this gets you started, feel free to provide model information for your router(s) if further help is required.

My wireless adapter keeps saying its disconnected

If the wireless router is far away this will cause drops, you need a stronger adapter, one with a larger antenna or one that has a antenna with several feet of cable so you can move the antenna closer to the source. You should also check for newer drivers, this can help.
Don't forget to use security.EX-WPA, Shared key, and so on.

My laptop which is hp 620 wireless connection switches on and off

I would have posted this in a Clarification, or Comment, but only have Post Solution option available at the moment. (SNAFU apparently in FixYa at the moment)

From your statements, it leads me to believe Electrolytic Capacitors; are failing in your wireless router. If it is an AT& T model, this carries relevancy. They have 'caps' that go bad.

Or perhaps the wireless module in the laptop is failing; or wireless antenna wires going to wireless module, are loose. (Loose connections)

This is a Service Manual. (Free)
It is in PDF file form.
The computer you are using now has Adobe Reader on it, which uses PDF files.

After you click on the above file name, it may take up to 30 seconds, before the first page comes up.
(Took 6 seconds just now using medium speed DSL connection)

Page 24. (Adobe Reader PDF page number at top)
Illustrated Parts Guide.

Page 30 at bottom. No.22 is the WLAN module.

ALL power removed, (AC adapter {Charger}, and Battery) Large bottom cover is removed to access it.

Page 66 - WLAN Module

WLAN Module - HP part number - HP 593836-001, or HP 504593-003

Click on the photo to enlarge. Note the gold plated contact pins in front. The WLAN Module plugs into the motherboard, using these contacts.

Tougher to explain; See the AS of Ascendtech?
Right above them is a small round gold plated terminal.

IF I am correct the White wire, from the Wireless Antenna, connects to it. (Terminal -> 1)
The Black wire connects to the other, small round gold plated terminal. (Terminal -> 2)

YOU will know for sure when you look at it.
The two Wireless Antenna wires, MUST go back they way they were originally, if removed.

The connector on the ends of the two Wireless Antenna wires, that go on the WLAN Module terminals, are flat female spade connectors.

They have a spring loaded 'Tang'. When removing the Wireless Antenna wire connector; the connector is slid off, pulling the connector back from the wire side. (Do NOT pull on wire, though!)

'Corrosion' can develop, on those small round gold plated terminals, on the WLAN Module.
It is advised to use a pencil eraser, and clean them.
(Gold isn't supposed to corrode. Just a term I used to try, and explain)

Rub the eraser all around the small terminal, and into the small shape of the terminal. The eraser will conform to the shape of the terminal, after rubbing a bit. (Eraser wears to the shape)

Suggest clean both terminals. Use air to remove the eraser dust.
(Keep your little fingers OFF of those terminals though! Your body carries Static electricity)
You can use a can of compressed air for computers, if available; or air pressure from your mouth will be sufficient.

Also clean the 'spade' connectors for each Wireless Antenna wire.
I know the eraser does not fit inside the connector. However after rubbing with the eraser for a small period, the eraser shape should conform, and be able to get in pretty deep.

Remove eraser dust with air.

If the connectors on the Wireless Antenna wires, seem to be loose on the WLAN Module terminals; GENTLY see if you can squeeze the connectors, using a pair of pliers. (Connector NOT on WLAN Module terminal, when you do!)

Check for fit. Must fit pretty tight.
Reconnect Wireless Antenna wires to WLAN Module.

Try this. If to no avail, suggest replacing WLAN Module.
(Get the correct one. Use it's HP part number)

[ Just for edification;

The two wires, Black, and White, of the Wireless Antenna; connect to the WLAN Module.
They then route up through the body of the laptop, (Through Channels, and Latches), up through the right Hinge.

(Look at Page 95 in the Service Manual)

From the right Hinge they feed up into the Display Assembly.
This is what the WLAN Transceiver with wireless antenna wires, assembly looks like, not installed in the laptop,

The silvery cylindrical looking object on the left side, connected to the White wire; and the object above it, connected to the Black wire; are installed in the LCD screen assembly ]

Signal not strong enough can I boost it

The "Wireless / Advanced" configuration window contains a setting for transmit power. Be sure it is set to 100%.
Otherwise, your only options are to replace the antenna with a booster antenna, or to add a stronger wireless router as an access point to your current setup. Using a booster antenna requires the D-Link to have a removable antenna, which it may not have -- none of the documentation calls this out as a feature.
Keep in mind that if you are trying to use this router over excessive distances, boosting the router's own power will not necessarily improve your connection, because the broadcast power of the remote PCs is also a limiting factor.

WEAK signal :-( How do I extend the distance or wireless reach.

Either look into getting bigger (higher gain) antennas for your router, or get bigger/stronger antennas for your PC's.

Other than repositioning the existing antennas or putting the router higher up in the air, there isn't much you can do.

Is the antenna removeable?

Yes. Typically they can be unscrewed from the back, but each model has its own intricacies, so you may want to look for a specification/data sheet for it.

Excellent signal low speed transfer

You can boost the signal range of a WiFi computer network in several ways: Answer:
  • reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of WiFi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.

  • upgrade the antenna on your router (or access point). WiFi antennas on most wireless base stations can be removed and replaced with more powerful ones.

  • add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.

  • add a bi-directional WiFi signal amplifier to wireless devices as needed. A WiFi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as WiFi transmissions are two-way radio communications.

  • add a WiFi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for WiFi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.

My wireless router signal is weak. How do i make it stronger so i dont have to be sitting next to my router to use my laptop?

connect wireless receiving antenna to laptop (if you have input for it in your wireless card), or connect transmitting antenna to router, or both

1 Answer

Very short range

No this is not typical if the Network card and router are just one room away. However electrical interference and walls do impede the signal.

Try moving the Router around to see if the signal improves.
You can also adjust the antenna and pointing it in the direction of the Router.
1. Position your wireless router (or wireless access point) in a central location.
2. Move the router off the floor and away from walls and metal objects. (Such as Metal file cabinets)
3. Replace your router's antenna.
Antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need most.
4. You can add wireless repeaters. (just the room next door this would be a last resort if all else fails)
5. Change your wireless channel. You may find one that will transmit a stronger signal.
6. Reduce wireless interference
If you have cordless phones or other wireless electronics in your home, your computer might not be able to "hear" your router over the noise from the other devices.. To quite the noise, avoid wireless electronics that use the 2.4 GHz frequency. Instead, look for cordless phones that use the 5.8 Ghz or 900 MHz frequencies.
7. Update your firmware or your network adapter driver
Nice diagrams on this web page too.
(Couple items left off as these did not seem to fit your current situation)

Good luck!

Wireless Internet not getting enought signal strength

Yea there are high gain antennas. Here are some on a site i would recommend

The more you spend the more purchase you will get. Go for one with a high dBi. Also be aware that you may want an omni-directional one if you want the signal to be boosted in all areas
