I replace it with a new one now the network signal not stable with my SIM
I flashed it with lollipop the problem doesn't solved !!!
any idea what to do ?

Hi,
I agree with Quester since it works fine with another SIM-card. Have you tried your SIM-card in another phone?

New iPhone 6 on new Verizon network, weaker signal

I just set up my new iPhone 6 on the Verizon network (coming from Sprint). I am only getting one bar signal strength now, in a major suburban area that always has good service. How can I tell if I am currently on the 4G network, or only tapping into 3G? My area show red on the map, but not the darkest red. Does that mean I don't get 4G here? If so, how can I set my phone to 3G again (if that will give me more signal strength).
Thanks.

My wife and I just switched to Verizon from AT&T. We have been seeing fewer bars of signal strength. I assumed it was due to the Carriers' signal strength. I wasn't aware that iPhone 6's are experiencing signal difficulties.
I'm not sure now if the difference we are experiencing is due to the different carrier, or to iPhone 6's. When with AT&T we were using 4s's and 5s's. We have LTE set to Data Only. Have not tried Voice & Data. We get LTE in most locations.

Weak signal from Airport Express on extended network

I'm receiving only 2 bars from my Airport Express even with devices right next to it (see attached pics). I've reset the Airport Express and the extended network setup goes fine there's just a weak signal. If I take my devices to the modem router I get a full signal. Any ideas?
iPhone 5S
iPad Air 2
Cisco Linksys Dual band wireless N modem Gigabit router

The AirPort Express does work with virtually any wireless router for AirPlay or a remote printer.
Unfortunately, you must have missed the following clear statement in the product information for the AirPort Express regarding extending a network.
If you already have a wireless network in your home and want to extend its range, AirPort Express can help. Just place it in range of your primary base station — an AirPort Extreme, AirPort Time Capsule, or another AirPort Express

Laptop Picks Weaker Signal on Extended Network, Why?

I've got an Apple Airport Extreme Router b/g/n and am using a Apple Airport Express Router b/g/ to extend the network. It actually works pretty **** well, giving a big signal way out into the backyard.
Here's the rub. My 'g' laptop, a Dell D620, always goes for the Apple Airport Express Router, even if the signal from the Apple Airport Extreme Router is twice as strong. The Extreme is channel 6 and the Express is channel 1. I can have the laptop right in the room with the Extreme and it will attempt to pick up the weak signal from the Express instead.
Any suggestions on this? Is it a quirk in the network extension that can be addressed? A consequence of mixing the Extreme and the Express?

It is actually on g/b/n. When I switch it to n (at least 5GHz, it totally disappeared from available connections.

I bought my iPhone 4 open line in Vancouver, Canada last week for use here in my home base in Bangkok, Thailand. But when I tried using my Thai sim, I get a very weak signal, if not a weak signal, then a no service status. What do I do?

I bought my iPhone 4 open line in Vancouver, Canada last week for use here in my home base in Bangkok, Thailand. But when I tried using my Thai sim, I get a very weak signal, if not a weak signal, then a no service status. I also have very weak wifi reception. What do I do?
I already tried the following:
a. Turned the phone off and then on.
b. Checked all wifi connections – no problem given that all our laptops and desktops can connect seamlessly.
c. I tried restoring the phone to original factory settings via itunes
d. Tried resetting the phone.
e. Tried different microsims from all networks
f. However, all methods failed given that the network reception is very weak and often reflects – “no service”. And with regards to the wifi reception It has difficulty in reading even the signal right in front of the wifi router.
I went to two Apple resellers here in Bangkok and requested that they please look at my Iphone and have it serviced. I was frustrated when they said that given that I bought my phone in Canada, they are not able to support me and should instead try to contact the Apple store in Canada.
I went to apple.ca website and went to the expresslane support and I was said to register and callback. Tried calling the 1800 number but given that I was in Thailand I had difficulty getting a connection.

E1200 - Had a weak signal and slow speed

Pros: Price, nice sleek shiny box, kind of worked when new. Good as a paperweight in a light breeze.
Cons: Not really a good doorstop - too light. Died at 35 days of ownership. Won't let me in to the web interface to make some changes. When working it had a weak signal and slow speed. Doesn't support access point mode like my old wireless router did.
Other Thoughts: Not the first time I'm had problems with Linksys/Cisco branded products but this is the last product I'll ever buy with the Linksys/Cisco name on it. Fact is ever since Cisco bought out Linksys, every product I've bought from them had failed/died within a few months. You'd think they would get this right by now but they haven't.

There are many reasons why you experience poor signal or connection. Well, there are few things you should keep in mind with regards to N routers:
1) For the best possible speeds, you need to be using WPA2-AES as your security mode. Any other security mode will see your speed/range capped.
2) Make sure the drivers for the Wireless Card for the computers should be updated as well..
3) The router by default uses a channel setting of auto, which means that it would keep switching channels depending on the interference. I’d recommend you set it to a fixed channel. Usually, 1, 3, 6 and 9 give you the best performance depending on your environment of course. I’d suggest you try different channels, observing each for a while, to see which gives you the best performance. You can follow the link here on how to change channels.
Second, all Linksys/Cisco can work as an Access Point. There are two (2) ways to cascade a Linksys router to another router:
1. LAN to LAN – Connecting one of the Ethernet ports (LAN ports) of the Linksys router (router A) to one of the Ethernet ports (LAN ports) of another router (router B).
This type of cascading requires the main and the secondary router to be on the same LAN IP segment to allow the computers and other devices to connect to both routers. This configuration is recommended if you want to share files and resources within the network.
2. LAN to WAN – Connecting one of the Ethernet ports (LAN ports) of router A to the Internet port (WAN port) of router B.
This type of cascading requires the main router and the secondary router to have different IP addresses. This connection makes it easier to identify which router the computers and other devices in the network are connected to since they will have different LAN IP segments. However, computers that are connected to router A will not be able to communicate with router B, and vice versa since they are two different networks.

Could weak signal be a computer specific problem?

I've read all of the other "weak signal" posts, and they all seem to be caused by an interference/distance issue. My problem seems to be particular to my iBook, as my roommate's iBook gets full signal anywhere in the same room as the express and at least half signal from across the house. Mine only gets full signal on top of the airport, half signal from across the room, and NO signal from anywhere else in the house. Also, this is true not just with our network at home; any other wireless signal comes in at half strength as compared to his on our "internet connect" meters. Wasn't until I had side by side comparison that I could confirm my personal shortcomings, but I had suspected for a while (wireless distance limit of 10 feet sure feels like the tug of a wire). I installed the airport card myself, while his came ready to go....did I screw up? Any ideas at all?

You may have your answer and I am going to throw out some info. I was having a lot of interference problems and Apple stepped up and helped out. First, and 2.6Ghz wireless phone will interefere with your network. Second, The airport has to have a clean line of site with the airport wireless card. Apple said they are finding the signal is having a bit of trouble going through metal, past microwave ovens etc. I have a G5 under a desk trying to get past a 30" cine display. I had to do some fancy work-arounds. Also turn on "interference robustness". It will slow your transfer rate down a bit, but it has kept me networked with little frustration.

My Airport Express has a weak signal 50-75 feet from base. Any solutions?

My AirPort Express has a very weak signal 50-75 feet away from the base. Any suggestions?

ideas
buy one (or two) of those newer md031 airport extreme base stations as they have a higher power output.
ur post is implying 'join a wireless network' so i dont think limiting to 2.4ghz or 802.11b or 802.11g would help..
using 2.4 or 802.11b would help over distances, if ur creating a network and joining it then thats not an option
the airport has a couple settings like power output (make sure its set to 100%) or multicast rate that might be worth trying out. multicast set to low helps with clients joining at longer distances and multicast set to high kicks off clients at distances
put the aiprort express up high on the wall so it has a better chance of not being obstructed ?? and not on the bottom of the baseboard??

How to force Airport to join an AP with weaker signal?

I'm trying to figure out if there is a way to get the Airport card in my MBP to join an access point, with the same SSID as another access point, but that has a weaker signal?
Say there's 2 access points (A and B) and they both have the same SSID (eg. Wayport_Access). A is on channel 11 and B is on channel 1. A has the stronger signal. By default, and normally, you would want the airport card to associate with the access point with the best signal, A in this case. However, I'm in the situation that A is not functioning properly. So I want to join, B, even though it's farther away.
I've tried using iStumbler to force a join with the B access point on channel 1, but nothing happens. I stay on A as long as it's the stronger signal. If I move such that I get to a place where B is the stronger signal I can then get iStumbler to get the Airport card to associate with B on channel 1. If I then move back to my original location where A is the stronger signal I do stay associated with B, which is good. However, due to hotel positioning and such, it's not always convenient or even physically possible to move to a position where the B signal is stronger.
I thought I remembered an advanced setting somewhere that would allow me to set something about stronger/weaker signal setting but I cannot find it in Sys Prefs.
Any ideas?

do you have the air port icon displayed in your top menu bar - if not add it in the system preferences ==> network ==> airport?
Yes.
Click on it and click join other network then sow networks and click on the one you want to force to - that should do it
Not if both Access Points have the SAME SSID, there's the catch. There's no mechanism through the Airport Menu or System Pref to join a different access point with the SAME SSID. That's why I was using iStumbler, because it will show ALL available access points, even the ones with the same SSID, based on which channel they are on. I want to associate with the access point that has the weaker signal, but has the same SSID as the access point that I'm already associated with. If IIRC there used to be an advanced setting about signal strength, but I can't find it anymore.

E2500 - Weak signal that fluctuates from weak to nonexistant

This router is really easy to set up but requires a ton of tweaking to get any sort of decent performance out of.
Even with these tweaks the signal is very weak. My old WRT54G had a stronger 2.4ghz signal than the E2500 produces.
Sitting one room away from the router and the signal is very weak. Forget being across the house. The WRT54G could cover almost the entire house with a network connection wirelessly, this thing can barely get a signal outside the room it sits in (same room the WRT54G was in).
What's great about it: Easy to set up
What's not so great: Weak signal that fluctuates from weak to nonexistant
This product has...
Unreliable connection
Short range
slow connection

The performance of your new router depends on various factors apart from the router itself. The wireless devices in your network, are they wireless G or wireless N devices? If they're wireless G devices, you won't really see any difference, and in fact any N devices in your network would also suffer because of that. Apart from that, placement of the router also matters.
Avoid keeping the router in a corner or under the table or something like that. Ideally you'd want to keep it at a higher location. The signal always travels better from a higher location to a lower location. Apart from this, you can also change channels on the router. Typically, wireless interference can cause poor signal strength and speed. Changing channels helps alleviate this problem to some extent. I'd suggest trying channels 1, 3, 6 or 9. You'll have to try each and observe which channel gives you the best performance. Every network environment is different, so what works for one network may not necessarily work for another. Please let me know if you need any further help with this.

Weak signal at home

Short of spending more money on top of the cost of my phone for a booster/repeater/whatever, is there anything I can do to improve the weak signal I have at home? The levels go anywhere from -106 (no bars) at worst up to -93 (2 bars) at best. Is there anything I can do to the phone to help it pull a stronger signal? The signal is weakest by our computer, which is exactly where I prefer to use the phone.
Comments? Suggestions?

Hi suzigirl,
I understand your discontent and frustration regarding the issues with your wireless service in your house. As per your post, you want to know of a way to improve your wireless signal indoors besides the Network Extender option. Lamentably we cannot guarantee wireless service indoors due to different building structural materials that interfere with wireless signal and the only option we are able to provide to improve indoor service is the Network Extender.

Airport Extreme - Weak Signal - 2 meters away

I just bought an airport extreme and after connecting it to the ADSL modem, my iMac is getting weak signal at times, down to 6 bar out of 15 bars. I don't get this problem with my old Netgear Wireless G router. There is no obstruction between my airport extreme and my iMac (about 2 meters away). Is there something I missed, please help.
Note: I noticed that my neighourhood has at least 6 - 7 open network (unprotected) and my iMac can see most of them, could that be the cause of my weak signal?

Pointdexler, Welcome to the discussion area!
Yes RF interference can cause problems with you trying to receive and connect to your wireless network. Try changing the channel used by the AirPort Extreme base station (AEBS) to one which is far away from those used by your neighbors.

Airport only connects with G5 door removed ... weak signal?

The Airport Extreme card in my G5 has trouble connecting to my wireless network when I move my tower away from my network base station ... it seems to be a weak signal that improves only if I remove the G5 case door. I reseated the the card and double-checked that the card wire was connected. Is the card going bad?

Weak Signal or No Service after upgrading firmware 1.1.2

I live in Los Angeles, Hollywood area, and for the past 2 months have had nothing but headaches with weak signal strength, no signal, dropped calls and slow data service. Sometimes the phone will have 5 bars then go down to zero bars or no signal without even moving! I think it must be the iphone/at&t service/software, since my friends on standard phones with AT&T seem to not have these issues.. I have seen on other message boards that other iPhone users around the country are experiencing similar issues...
No one seems to answer my question, "Could this problem be related to the Edge/3G combination have anything to do with this problem? The first 5 months of using the Iphone, I only noticed slight weak signal problems, generally related to having the wifi radio on. But this problem is occurring with wifi off. I have Reset the Phone, restored the phone, re-seated the SIM card, check to ensure SIM show no physical damage, all to no avail. You folks need to give me some real answers, and not just the standard we don't know. Now I must add there are some places like 6700 Hollywood Bl. where the signal is great both Voice and Data, but a 1700 N. Las Palmas the signal drops off to one bar, and at 1737 N. Las Palmas Av. it goes to No Service. Please help Please help!

You folks need to give me some real answers, and not just the standard we don't know.
Firstly, "we" folks here are iPhone users, just like yourself, not Apple employees (though there are a few who sometimes post here of their own volition, and not because they have to). So your problem will be answered or advised on depending on our own experiences with the iPhone. To that point, I am in the UK, and am one of those people who have suffered from exactly the same problem as you: my iPhone gets very poor reception in areas where other 02 (UK network) phones get near perfect reception. There is a rather long thread on this topic, and another similar one which was started when the original was locked by the mods. I'm afraid that after much troubleshooting, we are still no closer to finding the source of the problem. What seems pretty clear is that the iPhone antenna probably isn't as sensitive as those of other phones. Also, it's on the bottom of the phone, so can be covered with your hand causing a drop in signal strength. It may also be that in an attempt to conserve battery life, the iPhone doesn't boost the signal as much as it should. But there are all speculations at the moment.
You best best is to communicate your feedback directly to Apple at:

MacPro n card in MBP weak signal...this a possible cause?

After adding a MacPro card to my MBP CD I was surprised to see a weak signal when using an n enabled network (AEBSn). I was also surprised to see that g performance and signal strength was weaker also.
I know I wasn't alone in wondering why, but I think I may have found out the cause. Everyone knows that the C2D MB and MBP uses a 3 antenna array on a Atheros chip...however, the MacPro, AppleTV and probably the iMac all use a 2 antenna connection Broadcom card. Why only 2 antenna? Well, I think (from what I have read) that the 2 antenna leads are actually coaxial cables with a antenna within a antenna...what I think is called a 2x2 antenna array, allowing for MIMO and the high n rated speeds.
Thoughts? This has been bugging me since I installed the card and I just could not understand why I would lose so much signal and gain so much noise. Curious to see what everyone else thinks.

Same.. ish..
had a DG834G.. all fine..
gave it to inlaws..
got a DG834N
Apple genius said coz the imacG5 is G connected all is G.. fair enough kinda guessed that.
So hard wired the G5.
MBP still drop to 2 bars then hangs.. never had this with G.
AppleTV is further away and is 4bars fine.
Put MBP where imac is.. 3 bars.. itunes 720p footage stutters where same clip on iMac running atG would stream fine.
Think the MBP wireless is pretty pants, fine for surfing..
What i didnt know, as speed of wireless gets faster.. ie file transfer.. range drops.. so I get hangs on file transfers.
Gonna drop the router back to G in the morning see if that sorts it.
