Replaced antenna on 3gs but still not allowing calls

that's not how it works, the wifi calling is a replacement for your cellular network that allows you to stay connected better. all you have to do is set your phone to connect to your wifi network and then in the android settings there should be a "turn on wifi calling" setting that you can turn on and there you are.

You might want to get the phone checked out. Its possible the wifi electronics are going bad..OR your local wifi modem is bad. Try a different wifi network.

Move closer. That's not always an option though. Here are some tips to improve the range of wireless routers:

1) Locate the router higher in the building rather than lower (1st or second floor is better than a basement location).

2) Place the router in a location that will offer the least resistance to the signals - it is easier to pass wifi signals through gypsum board than it is for concrete / brick or walls with aluminum siding on them.

3) Change the antenna(s) on the router to a type that offers more gain. Typical router omni directional antennas offer 3dB to 5dB or gain - there are others that offer 7 dB or more of omnidirectional gain for reasonable prices. The antenna gain works for both transmit from and receive to the router.

4) if the device you wirsh to connect to the router is in one place, consider a directional Yagi antenna. These antennas concentrate the entire wifi signal in a direction that is 30 degrees wide and can allow the signal to be seen 5, 6 or even more times further in one direction - instead of being spread out over 360 degrees. These antennas cost a little more, but can solve the problem quickly.

5) Replace the manufacturer's stock firmware of selected routers with a 3rd party type such as DD-WRT or Tomato. Either of these will work with your Linksys WRT54G router. One of the benefits is the ability to boost output power of the wifi radio in the new settings the firmware offers. Read about both and decide if either is something you're comfortable doing.

6) Add additional wifi routers configured as a bridge or an access point to extend the wifi signal into an underserved area. DD-WRT supports bridging as shown here.

I hope this helps & good luck!

You can reboot ALL the devices . Unplug the Modem, remove battery, Unplug the D Link. Install battery in Modem, plug into AC, allow the device to selftest, plug in D Link allow it to self test. Reboot computer. Have you secured the wireless? Changed Channels for better signal? Take a look at this: http://www.microsoft.com/athome/setup/wirelesstips.aspx#fbid=nZTFiYrDLMg

I would try a software restore first. If that doesn't fix it bring it to Apple. If Apple doesn't replace it for you, you can find the logic board at iPhone 3GS Repair and there is a guide that shows you how to put in the part at iPhone Repair Guide.

this tends to be a common problem with dropped psp's . the reason that this happens when dropped it because the error has to do with the WIFI antenna . either its a very very low signal or your WIFI antenna inside your PSP is broken . you need to call Sony's customer care and get it repaired. i would not suggest doing it your self as it is very difficult to replace the antenna and it voids your PSP's warranty.

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.

it could be the connection on the back of the reciever that could be bad. I would call sirius and see if your reciever is under warranty still, if not i can almost garauntee that your tuner antenna input is bad, if your antenna is brand new.

Hi...
Some cable companies dont put the FM band on cable and some others put an FM trap (which kills the FM band) in line with the cable.
One of those is your problem.
You'll need to buy a FM antenna

Hi Philip,

To answer your question, from a single TX/RX device (your WiFi unit) to a dual antenna, what you would need as a splitter is more commonly called a "phasing harness".

A phasing harness is a balanced transmission line which is used when you want to stack or use two antennas from a single radio output. In lower frequencies it is made from a pair of 75 ohms high grade coaxial cable of equal odd quarter wavelengths of the operating frequency. The joint at the middle is connected with a “tee” connector with another cable (standard 50 ohms cable) that runs down to the radio. The free ends of the 2 75 ohms coax are then connected to the two antennas. This  site shows phasing harness for multiple antennas.

For microwave region, since losses tends to be magnified, commercial grade are often used rather than home brewed. Examples are shown in this page.

Alternately and perhaps simpler is to just remove the reflector of the 8Dbi patch antenna of the EOC 3220. Normally in designs such as the 3220, the active patch antenna is soldered on one side of the PCB.  At the back is another which looks just like it but slightly bigger. This is the reflector.  The reflector has two (2) purposes:
1.    block any signal coming in from and going to the back of the active patch antenna; and
2.    reflect any back signal of the active patch antenna and re-direct it forward to effectively increase the front signal.

If you decide to remove the reflector, there will be 3 effects on the performance of your TX/RX device:
1.    the front (major) lobe (roughly the front radiation pattern; maximum distance and area covered of the front signal traveled) will be greatly reduced;
2.    that reduction would be translated to a rear coverage; and
3.    it is highly possible that you will have small side lobes as well.

This   document  would give you an idea on the lobes and radiation patterns.

Good luck.
