Wireless AP Signal strength

You may not need to replace or move the existing AP:
How many antennas does that AP have?
If the antenna(s) can be removed, replace them with higher gain antennas.
That may be all you need.
You may also add antenna extension cables, but let's see your response, first...

Hello all, Periodically I encounter customers wanting to install new access points or replace ones they already have because the signal from the old ones is insufficient. I have site survey tools that tell me what the signal strength is like from an existing AP but I run into problems with interference. Case in point is one client where the AP is on a wall that borders an office. Due to the interference from the wall, that signal is down by half in that office, and in the next office (each office being about 12ft. wide) there is no signal at all. What I am wondering is whether or not there is a tool that can determine a signal strength needed given a maximum output power, since most APs give the maximum dBm, to get a signal through the wall. I don't deal with wireless placement every day so maybe I am going about this all wrong. Some...

Possible Noob Question: Correcting Colors From Cheap Digital Camera

I'm somewhat embarrassed to ask this here, but ya gotta start some place.
I'm a web dev so forgive my ignorance. I work with photos a lot, but they've always come to me from people who know what they're doing. I don't really understand digital -photography- that well---which is quite different I realise than film.
Anyhoo, I'm trying to get better colors from a pocket digital camera (Canon Elf 310) which (supposedly) has 12MP. The pictures I want to take for the job I have in mind involve clouds and landscapes and I gotta take a pocket came because we're camping/fishing.
Anyway, they -could- be very cool but the tests I've done show that the colors are going to be just -wrong-. And by 'wrong' I mean everything either seems -under- saturated or hyper-statured. For example... the subtle pinks in clouds are rendered as washed out or will be overly contrasty (hyper) yellow to orange.
The detail is quite sharp, however so does that mean there's something 'there' there which can be properly corrected? And if so, how?
If it's too wordy, perhaps maybe someone can just recommend a good text on the subject?
TIA,
---JC

I completely agree with Mylenium.
Beyond working with the various Tools in PS, for "Color Correction," I would start with a properly calibrated monitor, so that you know that what you are "correcting," is the Image, and not the monitor.
Next, familiarization with those Tools, such as Hue/Saturation, will be very useful. The Help file can get you started, by defining what each Tool can do, and a short-course on how it does it.
I would always work with non-destructive techniques, so that one can always go back and re-edit things. For that Hue/Saturation, mentioned above, I would use a Hue/Saturation Adjustment Layer. Same for Color Balance, and the rest.
Last, you eye should be your guide, on that calibrated monitor. Adjust, until you get what YOU like (or what your client likes). Remember that by default, most of those "corrections" will be "global" for the Image, BUT with Layer Masks, you can restrict/constrain the corrections to just certain areas of that Image. At that point, knowing about the various Masking techniques will be very helpful. Besides the Help file, there are many useful tutorials on various Masking techniques, and many will apply to Layer Masks.
Also be aware that different camera sensors might bias differently, and also with lower-resolution Images, you will likely not have a great deal of Dynamic Range to work with. Start with the best possible, from your camera. If possible, shoot in Camera RAW, and use the "processing" power of ACR (Adobe Camera RAW), to get started. You should be able to create a Preset for your camera (maybe shoot a McBeth Color Checker card, and calibrate that), to get that processing started.
Good luck,

Always low signal strength of my wireless connection

Hi,
I have new lenovo notebook ( 3000 n100)
my problen is that always my wireless network signal strength is lower then 60% even when my router is neer the computer !!
what can I do?

I would try changing the signal channel on the router. I don't know why, but sometimes wlan cards seem, idividually, not to perform so well on 1 or 2 particular channels.

Why does the wireless signal strength rise/fall on my Mac?

About two months ago, the wireless signal strength (from an Airport Express wireless router) on one of my Macs began to fluctuate. This machine is an adjacent bedroom from the router and has never experienced this problem until recently.
My other Mac sits two feet from the router and is fine.
I have moved the router a few feet in every direction with no change; have rebooted the Time Warner modem and router twice.
Every trick I know has failed to make a difference.
Any thoughts?
Mac in question: OS 10.6.8
OK Mac 10.9.2
Router is two years old.

Hi ....

Your Mac has been infected with the flashback trojan. The fix is relatively easy.
Installing this update Java for Mac OS X 10.6 Update 8 will remove the flashback variants.
Restart your Mac after the update is installed.

SNMP traps to monitor the signal strength on wireless AP

What snmp notification type should I enable on wireless AP to monitor the signal strength of the connected devices to the AP. What is the associated MIB for this SNMP trap.

Hi karthikeya,
Here is the link which gives us the info regarding the available MIB for the respective Model..

Possible to add a non-Apple signal booster to Airport Extreme to improve signal strength?

Good day to you all.
This might seem like a weird question. I've just rencently purchased my first ever MacBook Pro to enter the Mac family
With it, I also bought an AirPort Extreme. Like others today, I've had a lot of trouble trying to get the thing set up. I somehow managed to get it working, but the signal strength in the far room of the house is too weak.
I suppose I could just get a better Wi-fi adapter for that computer to pick up the better signals, but, my question is:
I have a signal booster (repeater?) from Cisco/Linksys that I used for my Cisco/lynksys router. It would connect to the network and bounce that signal from that base off to improve the signal strength to the rest of the house. It worked like a charm. So, my question is is it at all possible to connect a non-apple booster like this to the network to bounce the signal?
I assume it would work, but thought I'd ask anyway just to be sure; to check if anyone else knows about this. I'm going to try sometime soon if this works, but would love to know what others think.
Thank you very much for your time and help!!

Ah, yes. Good idea. Well, in a few year's time, we'll probably move on to better devices, but, for those who do have something that isn't Apple...I encourage you to try it.
I'm using the Cicsco/Lynksys Range Extender that I believe is simply called RE1000; mine was refurbished, too.
Anyway, it came with a set up disc that I'm not entirely sure if it works on a Mac computer. I didn't try it.
You'll run the set up disc (somehow), make sure you follow the instructions on the screen, and it should allow the RE1000 to find the network you created using the AirPort. Once the set up is complete, it'll ask you to move the RE1000 to another electrical outlet in your house that can take the signal and bounce it to a wider area of your house, and presumably the neighborhood (secure your network).
Seemed to work without a hitch. So, if you're not using an Apple range extender (another AirPort type thing), hopefully this helps you. It did work for me, otherwise I would have taken the AP Extreme back for a refund haha

Where to see signal Strength on wireless BR 350

I just purchased a wireless connection for my Tivo but the signal strength from my airport express does not allow the tivo to load data. How do I increase the signal strength?

I just purchased a wireless N network adapter for the TIVO premier and am trying to use my apple airport express to connectand it is in the another room. I am only receiving one bar of strength on my network adapter. How can I raise the signal strength of my airport express.

There are several things that might help, not all of which would be feasible depending on your situation: (1) Move the TiVo unit and AirPort Express closer together. (2) Use another AirPort Express to "extend" the network of the first AirPort Express. Put the second AirPort Express half way between the first AirPort Express and the TiVo unit. (3) In the general case, Power-Line equipment might allow the TiVo unit to get a good signal, but it's likely that the Ethernet port of your AirPort Express is probably connected to your broadband modem, so that solution wouldn't work for you. (4) Changing the band or channel that the AirPort Express is using might help. If the TiVo unit is connection on the 5 GHz band, try one of the three-digit channels, which are allowed to use higher power.

Can I configure a wireless home network with two cable routers (both with separate connections to the same cable company)? Issue is poor signal strength even with multiple Airport Expresses added to the network.

I have a wireless home network consisting of a time capsule, two airport expresses and a cable modem. Even with this configuration I get a very weak signal in much of be condo - the walls, etc. are solid concrete. I want to see if I can add another separately connected cable modem and connect one of the existing airport express to it by Ethernet cable. If so, this would give me two wired hubs and greatly improve signal strength. I do not know if this configuration will in fact work or if I will just wind up with two, separate and unrelateable networks. Unfortunately, there is no way to run any additional Ethernet cable and I doubt simply adding more Airport Express will help. Thanks.

Try Ethernet over Power adapters.. these are very popular for your kind of environment.. being able to make non-wireless link to another area where you can setup a wireless access point.
Airport Express are not great for wireless power.. if you really have issues with wireless strength in a bad environment apple stuff is not the way to go.
The comparison chart here.
http://www.smallnetbuilder.com/lanwan/router-charts/bar/58-2_4-ghz-dn?see=P_F
This is their worst test location you can also see averages.. the latest airport extreme.. is there a long way down.. and that is a much better wireless device than Airport Express.
The Ubiquiti power AP is small cheap and designed for precisely this duty.. useless in an apple wireless network.. you will need to run ethernet or EOP adapters back to the main router.. but if the normal omni directional antennas don't provide enough signal you can get directional ones.. I suspect you can cover your whole apartment with a pair of these and high gain directional antenna.

Won't connect to wireless network but indicates full signal strength

I just bought a new macbook pro last week and connected to my home's wireless internet immediately with no problems. Until this morning it was working fine. When i opened my computer and it woke from sleep it would no longer provide me with internet access. Both skype and safari won't work but my icon indicates that i have full signal strength and that i am in fact connected to my home network. I ran a diagnostic test and the result was that it "appeared to be connected" yet i still am not able to access the internet. When i plug an ethernet cable into my mac the internet works and all the other computers in the house (all non-macs) have wireless internet access.
Thanks for any help!

When i opened my computer and *it woke from sleep* it would no longer provide me with internet access.
Sometimes a restart will correct network problems since you are getting the full bars and the diagnostic test confirms +"appeared to be connected".+

My T40 shows connected to Wireless with Excellent signal strength but I can't open Internet Explorer

When I turn my T40 on it shows connected to my home wireless with excellent signal strength but I can't get the Internet Explorer to open and can't get to the internet. Please help!

(because I wanted it to have the same static IP address as the router).
Just wanted to clarify what you meant in this post. If you entered the router's IP address as the static IP for the laptop, you would get the symptoms that you are describing. Try entering a IP that isn't normally used like 192.168.1.142. (That is assuming that your router IP is the default 192.168.1.1.)
If that isn't the issue, please tell me what ipconfig is returning on both the laptop and the desktop.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Can I determine my wireless signal strength?

I'm using a Verizon router MI424WR. is there a way to tell the signal strength I'm getting? I'm using a wireless network adapter for my TiVo box in the other room. My signal is not always good but don' Know if the strength is poor because of my wireless network adapter or my router.

Your TiVO I would imagine can display at least a part of the picture as to how the Wireless signal strength is. If it doesn't, should you happen to have a Laptop, placing the laptop near the TiVo may give you an idea of the strength as well since that would more than likely report the strength.

Will signal strength or internet speed suffer when using a Generation 1 Time Capsule and wireless extending a network with a Generation 5 Airport Extreme

I have a wireless network in my home and I have a Time Capsule 1st generation and a Airport Extreme 5th Generation, will this cause my internet to be slow or have glitches with signal strength?

We've gone over this in the other thread.
If the Time Capsule will be connecting using wireless only, everything depends on the quality of the connection between the AirPort Extreme and Time Capsule.
The quality of the connection will be affected by the distance that the Time Capsule is located from the AirPort Extreme and any obstructions in the signal path.
If you have a ceiling between the AirPort Extreme and Time Capsule, then you should expect the signal arriving at the Time Capsule to have lost 30-40% of its bandwidth (speed). So, the Time Capsule can only repeat the weaker signal that it receives.
Other walls or other obstructions like heavy furniture, large mirrors, etc will also affect the wireless signal as well as cordless phones and other wireless networks around you.
If you are lucky enough to have line-of-sight between the AirPort Extreme and Time Capsule, then the wireless connection between those devices can work quite well. Few of us have this luxury, and must settle for significant compromises in performance.
If the wireless connection between the AirPort Extreme and Time Capsule does the job for you reliably, then you can leave things as is. If you are not getting the reliable performance that you need, then you will need to establish a wired Ethernet connection between the AirPort Extreme and Time Capsule.
As you might imagine, there is virtually no signal loss in a wire, even up to 300+ feet or 100 meters.
