I am trying to connect my iPad to the Internet without success.I am able to connect to the Wifi network but not to the Internet from there. This router (let's call it WIFI A) I am connecting to is connected via cable to the LAN main access point, which also works as a Wifi access point (let's call it WIFI B). Now I am able to connect to the Internet using WIFI B, but can't connect to the Internet using WIFI A.   I can normally connect to WIFI A, but no Internet from there. I can also connect to the Internet when using WIFI A with other devices and computers, but can't connect with any Apple device.   There are some options regarding the Wifi connections that I can change, but I don't know what to change.   Does anyone have any ideas?

I'm a relatively new macOS user. Let me try to describe the problem I'm facing as succinctly as possible  Just this morning, when I'm unable to get any internet connection even though WiFi is connected (full strength). All my other devices has no issues when connected to the same network (it's my home network)  I've logged into the router, and checked, there are no blacklisted IP/MAC addresses.  Additional information   I'm using a tMBP 15" for over a year I've had no issues with any WiFi connectivity to my home network before today. ping from terminal doesn't work as well. I'm able to connect to my phone's hotspot, and get internet from my MBP.  I have bootcamp set up. When I boot into Windows, I'm able to get internet access through my home WiFi   How can I troubleshoot this to get to the root cause of the problem?

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 :

Is there a way to benchmark how fast my router is connected to my PC, independent of the internet?  I've had slower-than-usual internet-based benchmarks, and I'm having a hard time figuring out if it's because of a bad router-to-PC connection (interference, bad signal, etc.) or if it's indeed because my internet is actually slower.

I have 2 pcs with win xp and a wifi router ( without outgoing internet connection )...my job was to connect them over wifi to share some files. router was properly configured, both computers connected to wifi without problems, but when I tried to network them I could not see them in workgroup...i changed their names and added them to same workgroup but i couldn't connect pc1 to pc2 ( i could ping router from each pc but pinging other computer resulted in ping timeout) ..now i cant figure out why this is not working since I've done this before on more complex networks and it should work but...( maybe I have gremlins hiding somewhere..)    edit1: Firewall is down on both machines( I disengaged it in both control panel and in services) and folder sharing and permissions are ok.. edit2: I know about Ad Hoc network ( wlan-to-wlan, without router/switch ) but that's not what I am trying to accomplish here :)

I have connected to my wifi correctly but I cannot seem to search for anything as it just says "Server Not Found". Other computers on the same network can still search the internet though.

After upgrade to iOS 13 from 12.4, I noticed that personal hotspot isn't working anymore over Wi-Fi (via USB is ok).  Tested on two computers with Win7. The PC can connect to Wi-Fi, but no valid IP (IPv4) is assigned and no connection is working to internet.

My wifi greyed out/dimmed for no obvious reason. To restore my iPhone I am required to turn off "Find my iPhone".  Since I can't get access to wifi through my device (it needs Apple ID password), how can I turn the that off?  I tried doing it through iCloud.com but it needs to be turned off through the device itself (which then eventually shows on iTunes).  I've contacted the Apple support team but they haven't helped much.

I am on an intranet that is not connected to the Internet and a Wi-Fi router with connection to the Internet. When I am connected to the wireless network, I can browse the Internet, but I cannot browse my LAN with my Ethernet cable connected.  How can I browse the Internet via my Wi-Fi router and at the same time browse my local LAN web application via my connected Ethernet cable?

Over the xmas period I am at my in-laws. They have Virgin Broadband (cable) and have a basic modem / router that is plugged directly into their computer using an ethernet cable.  My wife and I arrived with 5 PCs! (ok, one is a gift and won't be used) 4 of which are laptops so I would like to be able to use their internet connection.  At the moment I am working so have plugged the ethernet cable into my work laptop. Rebooting the router meant that my work laptop now has internet.  I have my ADSL Netgear router which is wireless. I tried plugging it in between the router and the PC but I didn't seem to be able to share the internet connection wirelessly. The original PC still had internet despite ony being connected to my router but my wireless laptop didn't have a connection.  My old cable router had an internet ethernet port on the back that the modem plugged into. My ADSL router doesn't, it has a phone connection socket.  Is there a way of doing what I want with the equipment I have?  Thanks

This may seem like a duplicate, but many solutions have been unsuccessfully tried. Currently I have no internet, WIFI or Ethernet. Sometimes: "no wifi adapter found".  The device is HP dm4, dual boot with Windows 7.    Here is the  The issue started 3 weeks ago as no GUI after 16.04 LTS to 18.04.01 upgrade.  At that time, I was able to use the terminal to connect to the Internet and run "fixes" in   Then mysteriously, the GUI ran after restarting several times.  But since then, I am unable to connect to the Internet in the terminal or GUI.    There is a chatroom  about my issues.  sudo nmcli c up &lt;saved WIFI connection&gt;   only appears to connect.   sudo nmcli d wifi list   shows strong signal strength, but ping to google and nyt fails.   The phone I use as a hotspot shows a successful connection.    In the GUI Network Tools show the phone/hotspot recently used minutes ago, the Available Networks list shows the phone/hotspot as available with a check mark, but the "connect" button is grayed out and unfunctional.    REGDOMAIN=00 and attempts to change this has failed as others describe. I have a similar set up to the one described by cipricus in  and the situation described in

Cannot connect MacBook Pro (Retina, 15-inch, Mid 2015) (10.13.3) to the internet through my Apple USB Ethernet Adapter. I am receiving this error under System Preferences/Network:   "Apple USB Ethernet Adapter has a self-assigned IP address and will not be able to connect to the Internet." IP Address: 169.254.59.248 Subnet Mask: 255.255.0.0   I can connect to the internet with the same ethernet port on my Windows 10 machine. When I replace the IP address with a the Wi-Fi IP address I use to successfully connect to the same network under "Using DHCP with manual address", the Apple USB Ethernet Adapter icon is green and displays the message "Apple USB Ethernet Adapter is currently active and has the IP address xx.xx.xx.252." However there is no actual internet connection (i.e., I cannot visit any website).  According to  to a similar problem, I can:   Find and disable whatever firewall is intercepting the DHCP return traffic. According to System Preferences/Security &amp; Privacy/Firewall, my firewall is off. Is there anywhere else I can check for additional firewalls? Would firewalls somehow impact ethernet and Wi-fi differently?  Inspect the network traffic or the router logs to see if and why the Mac DHCP broadcast packet is being ignored. How do I check network traffic on my Mac? I am comfortable using the terminal.

So my brother and I have been playing Minecraft together on our iPads for years now, but in September I got a new iPad Pro 3rd Generation and I’ve been having issues with Minecraft ever since. Every time we have tried to join each other’s worlds we get the message “Unable to connect to world”. Recently after the update on December 16th, it worked for about a week without having any issues, but now it has gone back to not letting us connect to the worlds. Both of us are able to connect to other people’s worlds, but not each other’s, we’ve tried many things to fix this but so far nothing has worked. If you have any ideas for what we should do please let me know, thank you so much!

I have a portable mini wireless router with different functions (AP/Client/Router).  Can I use a ethernet splitter to give internet access to two devices? The router only has a ethernet port and connects to a wireless network (Cliente mode).  I know that a switch would be the best option but I dont have one and they are expensive.

We have two iPads, and both of them have Minecraft PE. My son wants to connect the two and play with me. I have absolutely no idea what I am doing here, so I do not know how to do this.   One game says "Broadcast to LAN", and the other one says "Local Server Multiplayer". I have switched both to on.   What do I need to do to be able to play joined? We are both on the same WiFi.

I have two laptops running Ubuntu 12.04. Both connect to the same WIFI network to access internet.  How do I connect them to each other so that I can access files on one from another and vice versa?  Also, how do I manage the user permissions, etc. on them?
