What is a device that I can buy to improve my home Wi-Fi to all my devices?
My family has 3 labtops, 4 iPhones, and 2 xboxs that all require Wi-Fi. Therefore the connection on all of them aren't great, so what can I buy to improve the speed on all of them? I have an AT&T router.
Your question as asked is a bit vague.
You have 9 devices you wish to use with wireless access. You do not indicate if there are other wired or wireless devices also connected - and if you have secured the wireless to keep hackers off.
Remember that if you have 4 devices all downloading files simultaneously, each will see a speed approximately 1/4 of that see were only 1 device be downloading. This assumes all are downloading at the max speed your ISP provides you and none are being throttled back by a server that initiates the download.
Many people do not have all users downloading files at full capacity all the time; most users have intermittent download demand so the speed seems pretty fast when in fact this is due to intermittent demand.
If your router is undersized, you can see substantial delay when heavy workload is assigned to the router.
We do not know if your slow down is due to load demand of several users or an overloaded router.
You can do some testing to determine this by:
1. Measuring the speed using an Internet speed test site with the wireless capability disabled and only 1 pc connected via a wired link. This is as fast as it gets.
2. Second, change wireless password and connect only 1 pc via wireless link and disconnect wired link. Run test again. If the speed is markedly slower, the router is at fault. See if you can upgrade firmware and if that helps (go to router maker's site to see if you can get newer firmware). If firmware upgrade is not helpful, replace router with one with a much faster processor.
3. If the speed in # 2 above is roughly same as for single wired connection, add another pc to the wireless group and run speed test on both pcs simultaneously; continue to do this by adding 1 pc at a time and see if you notice a substantial slowdown. Make sure all wireless devices are in same room, near wireless router so we do not have a distance from access point issue.
4. If all are fairly fast and acceptable, then see if there's slowdown due to distance from access point by moving them to their normal use location. If distance from access point is the problem you may need to add more wireless access points.
All the above is a lot of work, but without such work we really do not know where the fault is.
- Will my jailbreak on one device transfer to another device via iTunes? So I bought an iPhone 5 today and I'm afraid to sync it to my Apple ID/ iTunes because my 8GB iPod is also synced to that iTunes account and its jailbroken. I don't want my jailbroken iPod to affect my iPhone 5. Will it affect it? I don't think it will but I just want to make sure before I sync it for the first time.
- How do you stop calls coming from one device coming to your device from iCloud (apple iPhone)? I'm 13 and i don't have a credit card so i use my mums account and since my phone and her phone has the same icloud, her calls come into MY phone and i've tried making a new apple id but it won't work so how can i stop it (i've already logged out on my phone) so how can i stop it?
- One laptop can connect to our home Wi-Fi network but no other devices can connect? We recently set up a wireless internet connection in our house. One laptop can connect to it (the one I'm currently on) but no other devices can connect to it. It says our "Network Security Key" is mismatched. I have tried typing in all the different codes on both the router and modem on both our second laptop and an iPhone 5. How can I fix this?
- No Apple devices can access the iTunes or app stores on my home network? This is an odd problem I haven't encountered before. The internet is fully functional, but whenever I try to access iTunes or the app store on my iPad, iPhone, or sister's iPad, it says "can't connect to iTunes store."
