Does a question E900 router have low internet speed?
Hi, I have an e900 router that says it has 300mbps but only supports 2ip cameras. My wifi is slow because there are two cameras on it, which slows things down to about 10mbps download and 2mbps upload. Even though the camera only uses a small amount of data like rtsp, my speed test shows me at only 10mbps download and 2mbps upload. I think maybe my router is broken or something else is wrong, but I'm not sure why.
So you have a WiFi router that can send up to 150Mbit (or actually only 72Mbit) but you are splitting that speed among three gadgets. You should probably turn off QoS because it won't help anything with the regular stuff on your computer or phone, and you don't really need it. I don't know how strong the signal is for those cameras; they might not be getting a good connection at all. If one camera has weak signal and sends data slowly, then ALL your other devices will get slow too. If there are lots of other people on WiFi in an apartment building like this, then you have so many signals fighting against each other that it's hard to use yours well. That router was made back in 2012 and is pretty old. You would be much better off with a newer one. Look for something labeled AC1900. Will changing the router solve my problem? I don't know how WiFi works sometimes. It most likely let you use your phone's 5Ghz band instead of the older, slower stuff.
The camera is right next to the router. There are lots of WiFi signals nearby, but the router doesn't support 5Ghz and neither does the camera. Also, why can't the router handle more than 150 Mbit? The box says it supports 300 Mbit but how do you figure out that speed? Even if it only gets 72 Mbit, shouldn't that work fine for one camera using rtsp? I thought an old router was enough. Would a new router make things better for me?
The "300 rating" means your client can handle two streams at the same time, but the cameras can't do that on their own. Your phone might be able to share the radio from a router, though everything still has to use the same line. Because of this, if one device is slow, everyone else gets slowed down too. Basically, most routers only work with 150Mbit clients. Since WIFI sends data in half-duplex mode (you can send or receive, but not both at once), that speed gets cut by half again. That leaves a real maximum of 72Mbit through the wire. But if you have lots of signal from nearby devices, it makes your radio busy and messes up the traffic. Things get tangled up and have to slow down and send over and over again. I don't know if a newer router will solve this. A crowded WIFI area just isn't good for streaming video anyway. I think you really need something wired instead.
Yeah I understand I need a wired setup. Also, is it wrong that 150/2 isn't supposed to be 75mbps? Why would they say 72? And QoS could help control how much bandwidth the camera uses right? Thanks for the reply
QOS doesn't work well for LAN traffic, so it uses up a lot of CPU power on routers that aren't very strong. Because of this extra load, you need at least 150 Mbit to handle the stuff without slowing things down. That's why I say 72 Mbit is enough.
Okay thanks you. Also, most routers have a splitter feature so if I get 100 mbps down and 25 mbps up, that doesn't really hurt my router's speed right? And since the router's actual bandwidth is split based on what direction it's sending or receiving data, and all devices are limited by their slowest connection, why does my camera only go as slow as its upload rate even though we try to send everything at once? Is there a guide or book that explains all of this? I want to learn more about how it works.
This is basic WIFI technology. Maybe start with something like this -- https://commotionwireless.net/docs/cck/n...ss-basics/ of this https://www.rvmobileinternet.com/guides/...damentals/
