Switch Download Slow

Chances are you'll notice pretty quickly if your Switch starts to slow down. You might experience unexpected frame drops while playing something, or you could run into controller input lag. Maybe it's taking longer for menus to appear, or to go away when you exit them. That same menu lag could apply to the Switch's system menu.
If your Switch feels slow, the issue may be due to your internet connection. Slow Wi-Fi could, for example, result in long loading periods, depending on what you're doing (trying to stream a video, for example). As well, a spotty internet connection could result in online games pausing for a few seconds or longer due to brief periods when the connection drops out entirely. To check your Switch's connection to your internet network, you need to:
I would stick with Cisco products as they are going to have the most power overall and best durability. That should handle what you need with plenty of room to grow. It sounds like it could be a broadcast storm or just that the switches are dropping packets. Both indicators of a switch failure of some sort. I would make sure no one has plugged in a little hub to itself or something around the office. Keep us posted.
One easy check for you is to look at the lights on the switches. When the network is normal, how do they appear? Whenthe network is behaving badly, how do they appear then? If all the activity lights flash when it's acting up, that's indicative of broadcast traffic.
Despite not being a nerd I still recommend looking at traffic, also define what specifically is slow. An application, file transfer, Internet, etc.... Without packet capture you could still use something like iftop to see traffic and usage.
What application is running on the Pervasive SQL server? If it's TriTech's IMC, be aware that there is a lot of network traffic starting IMC applications on workstations. I switched from Netgear 10/100 switches to HP gigabyte switches and saw an immediate improvement.
I'll second what Limey said, It sounds like a broadcast storm. If all the port activity lights are blinking constantly and in unison, that's a sure sign of trouble. If you see different groups blinking in bursts, that's healthy traffic. Without managed switches, my first step would be to shut down all the switches and bring them up one at a time to reset the MAC tables. With managed switches you could do this without downtime.
In the case a fast machine is talking to a slow machine the throughput of the slower connection will limit the two. But say Fast-A and Fast-B are communicating, they'll keep their fast speed with each other, even if they also communicate with Slow-C.
When a switch receives a message, it compares the destination MAC address to a table it keeps in memory. It then re-sends that message to the destination, using the correct port, and only the correct port.
Now, if you consider the situation where HostA is communicating with HostC, you have to realize that while HostA can send data to the switch at 1Gbps, the switch can only send data to HostC at 100Mbps. So, essentially, the communication will be limited to 100Mbps.
The switch itself works no problem when I press the switch manually, but using the app, it's very slow to connect (most of the time). It's fairly random, but it can take 20-30seconds for the command to be accepted (i.e., i turn the switch on or off, or I schedule the switch to be on/off), and sometimes I'll just get the message "attempt to connect to host timed out" or "connection error".
It sounds to me like there was a backend system change at Kasa, maybe a timeout setting was changed and now it's too short, I have satellite internet with very slow upload speed (1 mbps) and high latency (600 milliseconds). My HS103's are still OK and my only Leviton smart switch is also working fine.

I saw the same problem on my side, but I was alwasy able to resolve it by follow a plan:
1. Clean app cache on the phone, reboot your phone
2. it takes a few days for new smart devices to start performing
3. Reboot your switch (right button press on switch for 5 sec)
4. Check if you have too many wifi devices in particular access point, some weak/cheap AP behave weirdly if you have more than 40 devices connected. For pro AP 100-300 devices is not an issue.
5. Check if there is any wifi clients conneced to your AP with signal -78db and lower - these clients could cause wifi network instability, even if your other device has a good signal rate
6. Check for microwave nearbuy or bluetooth device or even Zigbee and Thread devices - they all can cause 2.4Ghz network instability as well.
7. Check for quality of electric connections on switch, in controlled by switch chandelier, try to switch light bulbs (could cause interference)
8. Check for wifi noise level close to the switch - your neighbour with his devices could be your issue as well.
9. Check your internet firewall if it is blocking any connections
10. Assign static IP to your switch.
..... and so on.
Good luck, I hope you will find your solution.
I have a site with an MX65 and a MS120-24P behind it. The internet circuit speed is 100M. The connection between the MX and MS is 1GB. When I have a user connected to the switch (with or without a phone in the link) that is only getting 20MB. If this user connects to the MX the speed is 95MB.
Last week, I bought the #300 Series SOHO Plus (GS308EP) switch. I can access and set up the switch via my computer. However, when I connect a POE device (IEEE 802.3af), the POE LED starts flashing green (1 sec on 3 sec off). I have set the switch port to 802.3af. What could be wrong here?
In the smart switch box the neutral from the power and the lights are all put together and then to the neutral on each switch. Then the hot line wire from power is coming in to a pigtail, then to each line on the switches.
I may have figured this out by telling the switch that the Maximum Level is something lower than 99. I think this depends maybe on the switch and the load, but both switches now appear to work. One at like 75, the other a bit lower. The lights no longer switch off randomly. I believe I read a post that may have said it might be an overheating issue with the switch, so that could be it.
Rapid spanning tree will not fix this. RSTP will do the same thing. The rapid part in RSTP is just figuring out topology changes in a multiple switch environment faster. End user ports still need it turned off.
It only matters if you are accessing more than 1 device from the primary switch from more than 1 device on the secondary. Your limited by the bandwidth of the single cable connecting the 2 switches. If all that matters is internet access then there's no need to worry as your limited by the speed of that connection which is often less than the connection between switches, but if you have a lot of internal traffic this could create a bottleneck.
ofcourse its possible, but this is a gigabit switch. this can literally handle 1000mbit per second over every port internally. so if you split the one internet connection over 4 left you get 250mbit per client. in reality this will be lower so lets take it safe and say you got about 200 left per client. this is more than adequate for any internet connection 99.9% of the consumers have.
If you have a single Cat5e cable going to your router, everything that goes through that cable is going to be limited to a maximum of 1Gbps. So, any data from the devices connected to the switch that needs to go outside your network (ie. to the Internet) is going to be limited to a collective total of 1Gbps. Unless you have an internet connection of 1Gbps or greater, this is not something you're going to need to worry about.
For local transfers, it can limit your transfer rates if you're transferring from multiple devices on the switch. With 4 device on the switch, it would theoretically limit each to 250Mbps each (250Mbps both ways at the same time due to full duplex), but it doesn't actually quite work like that.
if you have a gigabit internet connection and two clients will request hi bandwidth access to that internet connection, then the switch will throttle those two to fit in that gigabit - theoretically, each will connect with 500mb/s
here's another scenario when the gigabit switch will throttle the clients: one gigabit client connected to the switch is accessing the gigabit internet (let's assume you have gigabit internet) via the router, now a client connected to that router (let's say via WiFi) is trying to access a 2nd PC connected to that switch
PC1 to 4 are connected to the SW via gigabit; switch is connected to the router via gigabit, laptop is connected to the router via 150mbps WiFi (because it's shitty WiFi), the router connects to the internet with 1 gigabit/s bandwidth
because the PC1 to internet and laptop to PC2 have to share the same "path" (connection from switch to router is 1 gigabit/s), the switch will throttle down the PC1 to internet connection to accommodate the laptop to PC2
