Can't access Win 7 PC via Android phone over WiFi

Hello, this is my hardware set-up;

PC: Windows 7 Home Premium 64-bit.
Phone: Nexus 5 Android 4.4.2.
Modem Router: Netgear D6300.

My problem is that I can't access my PC via my phone over my wireless network, I have added the Nexus 5 as a Trusted Device in the Netgear settings so my phone can access the router and browse the internet and use email without any problems.

My PC is hard wired to my router modem, and I'm not trying to connect to my PC remotely (I heard you can't do this with Home Edition) just with my Wi-Fi network.

However when I try to use apps from the Play Store like AirStream, ES File Explorer, Astro File; and others the phone can't find or connect to my PC. I have the Shared Folders set to Everyone, Password turned off, Sharing and Printing enabled, plus an exception in the Windows firewall for the desktop software for AirStream, but still nothing.

I used to be able to connect to my PC with my Nexus 4*, both with AirStream and ES File Explorer to make use of the shared folders in Windows 7. I've tried disabling the Windows firewall for both private and public networks yet it still won't connect. I've also tried turning off the security in the router settings, and again it still won't connect.

I'm now at a loss as to why I can't connect my phone to my PC, especially as I used to be able to with the older phone*. I can only think I must have changed a setting either on my PC or Router but I don't know what as I've been through everything, even contacting the app developers.

*This phone is now broken so I can't try it any more.

This is driving me insane, any help fixing this would be greatly appreciated.

Thank you.

Id put my money on a firewall blocking you somewhere. This can either be on your p.c. (normally windows firewall.) or on the phone .... Or on the router its self ( very unlikely). Hows the phone broken out of curiosity ? I may be able to help

I don't see how it could be a firewall issue; I don't have one on the Nexus 5, also when I disable Windows firewall I still can't connect, and how would I know if it was the router firewall? What settings should I look for? The settings look normal to me. I've also noticed the official Android Net Gear Genie app won't connect either, it mentions something about disabling IPv6, but I don't see an option to do that.

The problem with my other phone is that the screen is cracked and the touch screen no longer woks, I then messed about with ADB and it no longer boots.

Thanks.

Sorry it shouldn't be your router firewall. The chance of that is slim to none. However to access and to turn off any automatic ipv6 settings you need to login to your router. Under Network > Interfaces in Frontview have you tried setting IPv6 assignment to off? You dont have any 3rd party antivirus that could be acting like a firewall on the pc?

That sounds really bad about your phone. It sounds like the booting issue may be fatal, but it would be hard to tell without the screen working. If the touch screen isnt working then the digitizer is broken. If its the nexus 5 then a new sceeen will be expensive. Like i learnt with my s4.

Under 'Advanced Settings' Internet Connection Type is set to Auto Detect. Then it says;
Connection Type 6to4 Tunnel.
Router's IPv6 Address On WAN
Not Available

LAN Setup
Router's IPv6 Address On LAN
Then a long string of code beginning with 2002:57f2:b2c6:e472

I have PeerBlock on my PC, but again I can disable that but it doesn't make any difference.

It's my old Nexus 4 that broke that could connect to my PC over my network, it's my Nexus 5 that I can't connect up.

Thanks.

Pair block normally doesnt cause me any issues. I do the exact same as you, i constantly connect to my pc via my phone. Hmmm can you set it to something different then auto detect? Because if its set to manual it may allow you to have access to Router's IPv6 Address On WAN

I tried changing it from Auto Detect to Auto Config and then Disabled, but I still can't connect to the Net Gear Genie app and I also tried connecting ES File Explorer again but I still got the usual message, 'Error can not find server.'

In the IPv6 settings page there is a drop down menu that says; Auto Detect, 6to4 tunnel, Pass Through, Fixed, DHCP, PPPoE, Auto Config. Each one has it's own subset of settings, and to be honest I have no idea what any of this means. I've now set it back to Auto Detect.

I've not heard any other Nexus 5 owners having this issue, I don't know what to make of it all, could the phone be faulty? I don't see how but at this point I have no idea where the problem is based. PC, router, phone.

Thanks.

I can see theres lots of problems with the wifi on the phone. But nothing about connecting to servers. It seems really odd and im running out of ideas what it could be. Try put the phone into air plane mode, then out again. Try it, if not repeat and then restart and see if that helps

Once you have created a new file or a file which you have already on your pc what you have to do is you have to give full permission (Read/Write) access to the file you need to share. probably you must to be the admin to do all that and
In ES File Explorer on your Android device, tap the globe icon in the upper-left hand corner, then navigate to Network > LAN and then On the menu at the bottom, tap "Search" to look for available network shares on your LAN. If you don't see any, make sure that your Android device and the Windows computer are connected to the same local network and try again. If successful, you should see your Windows computer listed with its IP address.Tap on the icon for your Windows PC, then enter your Windows username and password.
As i knw you should try with a password when sharing a file in win 7 just try it.

I tried that and it unfortunately doesn't work either.

I have shares and everything set-up on my PC and the Nexus 4 connected just fine, same thing with ES File Explorer and AirStream. When I tap Search for a network with ES File Explorer it just says "Scanning .... Successfully", but nothing happens.

As I already mentioned even the official Android Net Gear Genie app can't login, it says "Net Gear router is not found or is not supported. Also make sure the device is not connected to the guest network of the router, and no IPv6 is enabled." It isn't connected to the Guest network, and it connects to the Net Gear router for the internet and it shows up in a list of Trusted Devices along with my PC. And I have no idea what IPv6 means but as I've already mentioned I've tried those settings.

I think it's either a fault with the Nexus 5 or my modem/router, both are only a few months old and the router worked just fine out of the box as did the Nexus 4, but the Nexus 5 has never been able to find my PC.

I'm paying to get my Nexus 4 fixed and if it connects like it did before then I know the problem is with the Nexus 5 and I'll return it Google as faulty, if however it can't connect then I know it'll be a problem with the modem/router.

Thanks again.

I have an update: I got my Nexus 4 back with a new screen and case which cost about £95 all in. :) 
The phone came back with the original Android JB 4.2.2 that came with the N4, and I tried to connect to the PC but sadly the same problem exists.
I then updated to JB 4.3 and tried again, and sadly the same problem exists.
I then updated to KitKat 4.4.2, and again the same problem exists.

This is the phone that could originally connect to the LAN/Server, but now can't.

Am I right in thinking it must be the modem/router where the problem lies, and not the PC? If so I'm going to do a reset of the modem/router to see what affect, if any, that has on the problem. If that doesn't fix it then I'm at an even bigger loss as to what or where the problem is. :(

Well on Sunday I finally got everything working how I want, although I'm not sure how.

As I said earlier, I decided to try and reset the modem router which then created the problem of having no internet access at all on my PC, it seems I wasn't doing it properly. I was turning the modem router off before pressing the reset button, once I tried pressing the reset button whilst everything was still turned on, I got my internet access back on my PC.

Then when I tried the apps on my phone, they recognised and connected to my PC straight away, including the Netgear Genie app, AirStream, and ES File Explorer. :wahoo: 

I just wish I knew exactly what settings were causing the connection problems. The only thing I can see in the settings is that, in Mode it is now set to Auto, Wireless Isolation is turned off, and IPV6 is set to Disabled - No Internet Connection.

However, there must be other settings that are different as I'm pretty sure I tried all those.

It also looks like my Netgear D6300 doesn't fully support IPV6 despite a firmware update late last year.

Anyway, I'm just here to say that my problem is fixed, I'm not fully sure how, but it is. Thanks to those who offered advice and who tried to help, and I hope the thread can be of some use to others.

Cheers. :D

Lol thats really odd. Its crazy that all it needed was a reset. Im finding more and more often i have to say that things just randomly started working like it should for absolutely no reason.

But thats awesome to hear, really glad you finally got it sorted after all of that :D
