Both at home and at work I there are multiple Wi-Fi access points nearby with the same SSID and security settings.  My Samsung GS2 used to switch to the strongest available access point quite quickly. Now that I have ICS 4.0.3 installed it seems that my phone is sticking to the previous access point too long. This causes my network speed to very often be too slow as I'm consistently connected to "the previous hallway".  What are the solutions available to fix this issue? Is there a system setting I've missed? Is there an app that can help?

I have a wireless router (D-Link) in room A and a repeater (TP-Link WA750RE) in room B, both having the same SSID. Sometimes, when I go to room B and back into room A, my Nexus 5 (Android version 4.4.3) doesn't switch to the router although it has a stronger signal. It stays connected to the repeater instead.     The "Tplink" and "Dlink" are only aliases. Both actually have the same SSID.  When I switch the Wi-Fi off and on again, it connects to the router. which provides much better speed.  How can I force Android to always switch to the strongest signal? Is there a setting for it, or an app?

first question here. I was using wifi normally on my phone. Then I turned it off and after some time turned it back again. Since then I can not access the internet. It's showing Connected(no internet access).  I tried to set the IP static. It did not work for DNS 192.168.200.1. No matter what IP I set with this DNS it does not work. Then used the 8.8.8.8 as DNS, now it's connected. But it is really slow, and the connection does not seem stable. Every time I have to reload google.com several times just to get the page.  The problem is specific to this device only. Other devices connected to the same network are perfect.  Can someone suggest me what should I do? Is this a router issue? Or is this my device problem?  I'm new in this area. So my knowledge is not so deep and you might have to explain things a bit more in detail for me to grasp the concept.

Background  I have a 5th generation AirPort Time Capsule, bought refurbished from Apple about 6 months ago. It is on software version 7.7.3 and has worked without issue until recently.  Problem  Two days ago the performance of my AirPort Time Capsule's wifi dropped dramatically.  Whereas before I had no problem with AirPlay, or streaming videos stored on the Capsule over wifi, now videos buffer every few seconds, and AirPlay is chopped up to smithereens.  Web browsing is also noticeably slower, and file transfer speeds to and from the device have fallen through the floor.  Diagnosis  The problem seemed to start a day or so after I added an HP Envy 5530 printer to my network, though this could just be a coincidence.  To get an idea of exactly how slow the wifi had become, I put my Mac directly next to the Capsule and timed copying a 2GB (16000Mb) file to and from the device:   To: 390s ≈ 41Mbps From: 527s ≈ 30Mbps   Both are less than a tenth of the theoretical maximum of 450Mbps reported when I alt-click the wifi icon in the top bar, so something is clearly amiss.  To isolate the wifi as the culprit, I connected my Mac to the Capsule over an Ethernet cable.  I then saw that videos streamed without issue, files transferred at reasonable speed, and web browsing returned to normal.  To isolate environmental interference and/or my Mac's wifi client as the problem, I took the Capsule into the office and repeated the transfer using a  360MB file on a Windows laptop.  The results were even worse than above:   To: 88s ≈ 31Mbps From: 136s ≈ 20Mbps   Here is a screenshot from  taken at home while a slow file transfer was in progress.  The top two networks are mine (5GHz and 2.4GHz) and it shows there is no channel contention.  The transfer occurred around the middle 50% of the graph.    Remedy  I tried a few things to fix the problem, but with no luck:   Ran Wireless Diagnostics but no problems were found. Assigned the wifi channels manually to a few different random combinations. Specified a different SSID for the 5GHz wifi and tried connecting through that. Removed the HP software and deleted the printer from my Mac, and unplugged the printer from the wall. Performed a factory reset of the Capsule.   Next steps  Short of returning the unit to Apple, is there anything else I should try?

I have a Samsung Galaxy S3 and have it updated to 4.1.2 from ICS. If I restore my phone to factory settings (either by going to settings or by rooting), will I lose my updates? If so, is there any other way to restore without having the above setbacks?

I'm soon going to be setting up a wireless network for me and some buddies and (hopefully) making it secure. I have some questions and concerns regarding this and figured someone here could give me a hand and steer me in the right direction.   I have a WRT55AG (version 2) loaded with the factory firmware. I've heard that it's possible to load your own firmware onto routers like these. Is it worth it? What can be achieved with it? I was wondering what kind of security I should use on my wireless. Ideally I would want all devices to be 'accepted', but I'm not sure how to accomplish this. I'm guessing it has something to do with MAC addresses, but I don't know the first thing about them. It would be great that ALONG WITH encryption (I'm told WPA2 is the best), every device would need to be added to a list of some sort before even being able to access the AP. Another feature I was thinking of would be completely hiding my wireless from showing up on other people's computer. Is this possible (like an SSID broadcast thing). Is it worth the trouble? One more option I was looking to implement would be bandwidth calculators. Ideally something in the router to measure the amount of bandwidth being used and how much has been used for that month (this has to do with bills and limits, obviously). Is it possible to throttle down speed when a certain limit is reached?   These are alot of points but I was hoping someone who has more knowledge than me in this subject could give me a hand and a few pointers. Hopefully all this is possible and I'm not dreaming :)

I configured my new router and noticed that WiFi connection is way slower than Ethernet connection.   Ethernet connection giving a download speed of ~60Mbps and upload speed of ~30Mbps while the Wifi only giving download speed of ~20Mbps and upload speed of ~15Mbps.  This is a new router with 802.11n and it says it support 300Mbps.  Here are the Wifi settings of the router,is there anything I can change to get higher speed :

So currently when my non-admin user tries to connect to  a new WiFi network (e.g. at a cafe say) NetworkManager prompts for the admin user's password. Is there a way to turn this off and to allow the non-admin user to connect to whatever Wifi network they like?  EDIT: just to clarify, I really mean a new WiFi network never connected to prior by the computer, so clicking 'Available to all users' on an existing established connection will not solve the matter- as currently no issue with the non-admin user reconnecting as many times as they like to the home network.

I recently upgraded from Ubuntu 16.10 to 17.04. In Ubuntu 16.10, I could setup a WiFi hot-spot to give Internet access to my Android phone using the trick mentioned in this article . I can connect to WiFi now using the fix mentioned in answer to this question: .   But when I click on "Connect to Hidden WiFi Network" and choose to start the hot-spot setup, I see this notification and it doesn't start.    How should I resolve this?

Whenever both my roommate and I use the wifi in a certain room in our apartment, it slows dramatically for me. It doesn't slow for him. If he uses it in another room, it's fine; if I use it in another room together with him, it's fine; it's just in this particular room. Does anyone know of a reason this could be?

I've tried everything I can think of. Resetting the router, changing the channel number and band.   The internet connection is fine, and then just hangs for a minute or 2, then returns to normal.   The wifi icon remains connected, and I have the latest 10.10.4 update installed. At first I thought it was a DNS bug with Yosemite, and have played with the settings such as changing DNS provider, changing the IPV6 to IPV4 only etc.  Driving me nuts. Has anyone had a similar problem? I've checked the surroundings with wifi scanners and have chosen the best channel available.     One thing I have noticed, it seems a lot more reliable on 5GHz as opposed to 2.4Ghz It seems to affect my Macbook Pro Retina 13in Early 2015 a lot more than the other devices on the network. I'm using a Virginmedia  1.

When my cellphone accesses a website via the tower and its GPRS gateway, NAT ensures that the sites receive a public IP. Would all phones using a single tower have the same IP?    If yes, then how can the mass of received HTTP data routed to the correct cellphone? And how can websites differentiate between cellphone visitors? Is there additional HTTP header data? If no, then how are these unique IPs assigned? Based on availability or location? Would each tower have a fixed set of IPs?

In Ubuntu 11.04 I used InSSIDer to scan the available APs and sort them by signal strength.  Unfortunately the program seems to be broken in Ubuntu 11.10, and   iwlist wlan0 scan   doesn't return anything meaningful.   What options do I have to scan for available Wireless Access Point, possibly with a GUI?

I'm having trouble understanding what I'm doing wrong here: I'm trying to set up two network Locations, one for my home network via my cable modem and a second for Wi-Fi tethering via my mobile phone. What I'd like to be able to do is change the Location (under the Apple menu &gt; Location) and have my Mac automatically connect to the proper Wi-Fi network: either my home network SSID or my WiFi tethering SSID. I defined two locations, switched between them, and set the preferred network list for each location. But when I change the preferred network list for one Location, it changes the list for the other Location as well! Am I doing something wrong or is it really not possible to maintain a separate list of Preferred Networks for each network Location? It seems doubtful it's not possible since just about every other netrok setting depends on the location... I am using OS X 10.7.2.

I 'm trying to install wireless access point device EP-2906, on my Desktop PC running Windows 7. Here is the  .  Page 7 says how I can set up it's IP address, but I can't find Wireless Network Connection icon. Is this because of my Desktop PC and in this case how can I set up a static private IP address for this device?

Occassionally my Wi-Fi goes into this weird state where the phone "thinks" I'm connected, but the connection simply doesn't work.  Apps still seem to think I have connectivity, though they can't actually connect to anything, and the status bar still shows that I'm connected to Wi-Fi.  Turning Wi-Fi off and back on resolves the issue, and this occurs on multiple networks.  It seems sort of like whatever service manages the Wi-Fi connection gets killed occasionally.  It usually happens when I've been playing a game (that doesn't access the Internet) for a while or if my phone's been sitting for a while; it never happens while I'm actively using the connection.  I have my Wi-Fi timeout set to "Never" and the normal timeout isn't the issue since my phone regularly lasts several hours without the Wi-Fi dying.  Sometimes it dies a couple times in a day, and recently I went a week or so without it happening.  How can I fix this or prevent the service from being killed (if that's indeed what's happening)?  Shouldn't that be a system process that never gets killed?  (Does Android ever kill system processes other than when they crash?)  Could it be related to TouchWiz?  I have an SGS Vibrant running 2.2 (Bionix NextGen v1, but this has occurred on multiple ROMs).

I'm having severe issues w/ package-loss and a generally bad connection w/in a WiFi-network at my uni. I'm usually encountering a package loss of ~50% and aborting connections which makes working w/ SaaS impossible.  I'm using Ubuntu 13.04 and my network-adapter is an Atheros AR9462.  Applying the nohwcrypt=1-option doesn't change anything.  Also very noticable: The connection works as intended in other networks; the problematic network uses WPA2 w/ MSCHAPv2.
