Iphone 3gs extreme weak wifi signal with wrt160N - suggestions?

Linksys wrt160N v3.0.00 build 010 Jan 30, 2009
iphone 3gs firmware v3.1.2
Set up network to include a few laptops with N cards, a PS3 – all ok
When it comes out of sleep mode it connects at full signal strength , then within 15 seconds drops to just the one dot
Under a dLink G router, full signal strength right up to 30 feet outside of the house
Here in condo just purchased the Linksys and standing right next to it i get a practically non existant wifi signal
Go back to parents house with g router , works perfectly.
I thought the N router is set up to be backward compatible and if need be broadcast in G mode for G devices
Is there anything I should be aware of in the settings.
I followed the basic setup - no manual fiddeling with any of the settings.

1. You can check all the settings through the web interface at http://192.168.1.1/
2. As long as your iPhone maintains a connection and does not really slow down it does not matter how many bars the iPhone shows. I think the iPhone has problems calculating the correct signal strength on 802.11n routers. I have seen something similar on a dlink router. My iPhone jumped from 5 to 1 and back. Most of the time it was at 1 bar. Yet, I had perfect connections and normal internet speed. Thus, check internet functions on your iPhone. Unless you loose connections or they get extremely slow I would simply ignore it.
Problem being is that I'm not sure where to check via the web interface as to what mode it's on right out of the box.
The only way, recalling from last night's attempts, is if I go in and select the manual settings option rather than the wifi protected button, which would then allow me to enter manual settings.
Only there, would I know what it would be set at because I would obviously have to set it. I'd rather not go into changing manual settings unless absolutely necessary at this point.
As for the iphone not displaying the signal strength correctly - I'd have to say it is, given the following download speed test results: 27, 95 , 28, 149 kbps (not the most spectacular) compared to say 9388 kbps when the iPhone initially comes out of sleep and connects to the network. The signal drops to the one dot within about 10-15 seconds approximately.
With the old dLink G router, the signal strength registered full and download speed tests supported that, same as outlined above with the weak signal and corresponding d/l results.

Iphone 3GS very weak wifi signal since 4.3.3 update

Ever since i update to 4.3.3 (which I'm regretting now) my iphone will not connect to my wifi router unless I'm less than 3 feet from it.
My wife has a 1st gen IPod touch (which hasn't been updated) can pick up the wifi and connect to the wed with it upto 30 feet from the router, as my iphone used to.
Is this a 3GS issue as i've read some other posts about a similar problem. I'm not willing to accept this as a hardware problem as the minute before the updating to 4.3.3 my wifi signal strength was prefect, the minute after the update was complete the signal strength was and still is worse than sh*$e.
I have done all the power down resets as suggested on other posts, but it doesn't work.
Is there anybody out there that can tell me how to (if possible) to revert back to 4.3.2?????????????????????????????????????
RLB

I don't have the answer to this issue but I'm experiencing the exact same problem.
Since 4.3.3 my wifi signal strength is close to nothing. When I'm 3 feet away from any router, at home or at work, I have 3 bars not even full reception. As soon as I walk a few yards away from the router, I lose the connection completely.
I've tried everything to fix this. Reset network settings, turning off Bluetooth, disabling location services, full restore, reconfiguring routers, etc. but nothing works. I'm now using the iOS 5 Beta 3 and still no improvement to this issue.
In this thread there seems to be some recognition from Apple that this is a known problem and indeed a software bug. Hard to know if it's true though:
https://discussions.apple.com/thread/2815831
The same weak wifi signal seem to happen to iPad users too: https://discussions.apple.com/thread/2387493 This thread dates back over a year, so it looks as if this problem is common but without fix.

My iPhone 5 has weak WiFi signal.

After the latest update, the issue was solved. However, today the signal became weak again. The sign only shows "a dot" of the signal strength wherever I go. Do anyone know why is it??? It seems so weird to me that the problem just suddenly happened. I didn't drop my phone what so ever.

Hi - I would first try and reset the wireless - go to Settings --> General --> Reset --> Reset Network Settings - if this doesn't help then your phone is still within the 90 day support period so you can contact Apple online or at an Apple store if there is one nearby - go to this link - http://www.apple.com/support/contact/

Can anyone tell me or give me a link to the latest response from Apple regarding very real weak wifi signal on what seems to be a batch of both the new ipad and the earlier Ipad2. I have just bought a 2nd hand ipad2 and it has a very weak wifi signal

Over the last week or so I have been trawling the internet looking for references to weak wifi signals on the Ipad2 and was staggered by the sheer quantity of people who seem to have identical issues, not just with the ipad2 but also with the new ipad. What annoyed me most from reading the reams upon reams of comments made on the Apple community forum is the fairly large number of people who seemed to believe that 'these' people were either just moaners and wingers or else they must have something wrong with their router set-up rather than a serious fault with their ipad and it seems all because there ipad in question works like a dream.
Obviously I can only speak from my experience, and that is, I have an ipad2 32GB with wifi, purchased about 6 months ago and it works like dream with a good 2-3 bar wifi signal through 2 thick stone walls over 30 feet away. My router is a standard one supplied by my broadband supplier compatible with all 'g','b' and 'n' equipment. However, over a week ago now I bought second hand genuine ipad2 16GB with wifi from a close friend who has just purchased a new ipad3 to replace his old ipad2 (had it for over a year so no longer under warranty). When I started it up downstairs from my router, where I always use my other ipad2 which has a very strong wifi signal, I discovered that the new secondhand ipad2 I had purchased couldnt find a network signal at all. So after doing network resets and all other 'fixes' on the device recommended, I took it upstairs to my office where the router is based and found that the device could now locate the network, but the signal was lost over only 12 feet from the router!
I quizzed my good friend about this issue and he informed me that it has always been like this since he first purchased it and he never thought that it was a fault, it was just the way it was. When he first aquired the device he did think at the time that this distance was poor, but thought nothing of it as he didnt have any other ipad to measur ethe signal strength against, and as his router was in his living room anyway he nothing of it. Fair enough.
So, there we have it. One ipad2 with a very good wifi signal and another ipad2 with a very poor wifi signal running off the same router, both with the same IOS 5.0. ?
As well as all of the other isues that customers have picked up on, such as 'death grip' (which I must say does appear to happen, but personally i dont think that this is a serious issue if you are aware of this issue and have a strong signal anyway), my experience seems to be a good example of a 'duff' wifi ipad versus a 'great' wifi ipad', an issue confirmed by complaints from a fairly large number of customers who have also reported the same or similar weak wifi signals with both the ipad2 and the ipad3. So, as this shows the weak wifi signal is a very real issue it seems on a batch of ipad2 and 3's, which to my logic is obviously a hardware issue on a batch of early ipad2's and not a software one, otherwise all ipad's would suffer this problem! So, is it a faulty antenna or a faukty network card in an early batch?
So, the bottom line now is, of course, firstly, how can I get Apple to fix my other ipad2 when the warranty has run out? Any suggestions anyone?
Personally I think good Apple customer service should offer a recall with a replacement on this apparent batch of ipads, dont you?

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Airport Extreme (5 Gen) suddenly very weak Wifi signal

Hello, everyone. I have a 5th generation Airport Extreme that was working fine until a few days ago. My power had gone out, and since then I am getting a very weak Wifi signal. The network still appears and connects on all of my devices. However, it is dreadfully slow (0.3 MB/s per Speedtest.net), whereas before it was 50 MB/s. I have tried resetting to factory settings and opening up the option to 5GHz. The 5 GHz wireless network works just fine on my iMac. It doesn't show up as an option on my iPhone, though, and that's what's really bugging me.
I'm wondering if anyone else has had this problem and can help me out. Of course, my phone support expired a few months ago and now they want $19 for a tech call. Any help here would be greatly appreciated.
Thanks!

Reset to factory again.
Setup again using all short names, no spaces and pure alphanumeric. If you were doing this make sure you use different names. Empty all the old names from the clients so they start over with fresh clean setup for wifi.
Use a different name for 5ghz.
Use fixed channels.. try 1, 6, 11 for 2.4ghz and try 36, and 150 for 5ghz.. around about.. exact channel is not such a big thing for 5ghz.
Check the link speed and make sure it is full speed if you are in the same room as the AE.
Test by copying a file on the local lan.. rather than testing to internet which could be a totally unrelated issue.
Test by using ethernet only on a computer plugged into the AE to see if the internet link has gone slow.

Sudden Weak WiFi signal on 3Gs

Over the last month or so I've experienced a big drop-off in my 3Gs's ability to latch-on to my local home WiFi signal. I've not recently upgraded, or changed settings on the phone. An example; my BT Home Hub router sits in my office and casts a strong signal throughout my timber-frame house, (and I know the signal's still fine because my 3-yr-old Macbook, which I use anywhere and everywhere, and spanking new iMac display full WiFi bars and the speed is excellent.) I normally access the web via my iPhone from my living-room, which is no more than 20 Yards from the router, and up until a month or so ago, enjoyed a full reception on the iPhone also, but now nothing. Zilch. (There is one small corner where I can sometimes pick up one bar.)
I'm composing this message on the iMac, which displays the full WiFi signal, with my iPhone propped up next to it and displaying zero WiFi reception. We are about eight yards away from the router.
(I realise this topic is closely linked to others already posted, but it's something that Apple should really be responding to; they obviously have people who keep an eye on forums like these to monitor feedback about their products, and connectivity issues seem to be a bit of a hot potato at the moment.)
My hunch is that the iPhone's capability to receive a WiFi signal has somehow become compromised, being as all other devices - and Apple devices at that - work fine.
Can somebody help.
Thx.

Weak WiFi reception seems to be a suddenly common problem. We just traveled to Holland last week, and all three of our iPhones were useless, and unable to pick up wifi signals. We got back to the states, and the problem continues.
My iPhone must be within a few feet of a wifi router or will see no signals. I visited an Apple reseller who told me to update my iPhone software to solve the problem. Now I have NO signal reception unless my phone is at the router... any router.
Today I went to the Genius Bar, where the Genius reset my phone, and told me I have a hardware problem: my wifi card in my phone is no good, and I have to replace my phone. I thought this was suspicious at best, turned to the forums, and discovered many, many, many people have the same problem!!!
We can't all suddenly have the same hardware problem, but we all can have the same software problem. This seems to be a well known bug based upon what I've read here.
I am about to do a total RESTORE on my iPhone to see if it solves the problem.
I agree with another's comment: Come on, Apple, fess up and fix it.

I have Direct TV with wireless, but a weak wifi signal downstairs. Can I get a Airport (what,kind) that will improve my signal for my Apple TV

I have Direct TV with wireless, but a weak wifi signal downstairs. Can I get a Airport (what,kind) that will improve my signal so that my Apple TV will work?

If you have an AirPort Extreme now, an AirPort Express could be added to your network to extend the range of the network.
See the info about Extend an Existing Wireless Network.........http://www.apple.com/airport-express/
Install the AirPort Express approximately half way between the AirPort Extreme and the point where the Apple TV will be located. The more that you can eliminate obstructions like walls, a ceiling or heavy furniture in the signal path between the AirPort Extreme, AirPort Express and Apple TV, the better the network will perform.

Boosting o2 Wifi signal with Airport Express

Dear all,
I had read that one could boost our o2 Wifi signal with the Airport Express. I don't seem to be able to do it! Can anyone help.
Detsky

It is possible if the wireless network is created by another AirPort Express (AX), an AirPort Extreme base station (AEBS), or a Time Capsule. Otherwise it is not possible.

E90 Very weak WiFi signal

My E90 has a VERY weak WiFi signal, and in places I regularly use a 9500 and my laptop with no problem, my E90 simply will not work e.g. from first floor to ground floor. If I move closer to the Wireless router, then it is fine on both Email and Web.
So it seems purely that the strength on E90 is far weaker than 9500.
Has anyone else found this?
Is there any way to alter signal strength in the various WiFi settings?
Or is this yet another shortcoming of E90 over 9500?

Yes I already altered Tx power settings. Thanks for suggestion. Makes no difference.
It really seems this E90 just has a vastly lower power WiFi rating than my 9500.
It is very tedious to be unable to connect even within one's own home and frankly renders the phone totally useless, quite apart from all the other problems well documented on here.
I think I can see why so many are up for sale on Ebay.
Does anyone at Nokia read these discussion pages and does anyone care that their products seem to fall short in SO MANY aspects?!
That's right, it seems no one reads these discussion.
However, if u have ur problem solved, pls advise

Linksys EA6700 very very very weak Wifi signal

Linksys EA6700 very very very weak Wifi signal
Anybody faced such issue with this immature router? I was using E4200, the signal was much better. I thought of upgrading to latest “high-end router”, unfortunately it is not an upgrade it is a rip-off. This router is not stable at all.
I will switch to NetGear, any recommendations?
Thanks & best regards,

tangbunna,

How are you trying to transfer it and what are your setting on iTunes. I'm not on a computer that has iTunes at the moment so I'm going from memory and similar issue. If iTunes is set to sync music then I don't think you can select and drag, if set to manual manage music then you can. Also make sure you are dragging to music on the iPhone.
Hope this helps
