I have small network in my building where i have a ISPN router from where i added two tp 300 mbps switches on each two port to share internet through ethernet cable with routers provided at each client. now i am having problem for frequent loss of internet at client router and every time i have to restart my main router and reset switch then client get back internet. kindly provide solution to my problem. Will replacing of switch with giga byte will help me or what is the problem. Normal time ping it ok no loss.
 
Not sure what kind of switch you are using. Switches generally are 10/100 or 10/100/1000 I have never heard of 300m switches.

A switch should be totally transparent. If you can always ping the router ip even when the internet does not work it is going to be some issue with the internet not related to anything on your lan.

Try to ping 8.8.8.8 when things are broken. You might have a DNS issue instead.

apology..switch are 10/100. I get red lights on client routers when I face this issue. Do huge traffic also have some impact on switch? Or how I can check wether this issue is of ISPN or swit h??
 
You would have to check the back plane speeds in the switches but unless they are extremely old the switches are not a bottleneck. Most modern switches can run every port at full speed up and full speed down all at the same time. So a 24port gigbit switch would have a total throughput of 48gbit/sec.

If you are getting a red light on the wan connection then the ISP connection is physically going down.

i am still verifying the issue meanwhile i want to provide more details for the layout of network so you can suggest whether it can be a bottle neck? following is the layout of network:
Main Router(LAN PORT 1 & LAN PORT 2]
LAN PORT 1 TP LINK 10/100 1 Switch attached with client router attached through Ethernet cable in Wan port
LAN PORT 2 TP LINK 10/100 1 Switch attached with client router attached through Ethernet cable in Wan port + Another Switch attached in series to extend more port
 
Your switches will not cause a internet outage that requires you to reset the connection. All the devices on switch #2 as well as all the devices on the switch you connected to it share 100mbits on the router port. This likely makes no difference unless your internet connection is more than 100mbits. Even if it is more the worst that will happen is the devices will run a little slower it does not cause the connection to go down.

When you have lots of pc connected to a network there is always the issue of a misconfigured pc possibly causing issues but since you are getting a red light on your router I would suspect it was some kind of internet problem instead.

Thanks bill001g for your kind info. your info is working for me as i need little more advice that whether aging factor and heating of switch can contribute to internet loss on client router? if yes how can i check to replace the switch as i am using TP Link low cost switch. Further, no PC client is using on client router all user are for mobile. one more question if all client device are router and one of client is using Access point will it make any trouble on network moreover, trigger of WPS function on client router can cause trouble on network?
 
WPS needs to be disabled there is a massive security exposure that can't not be fixed. You need to not be lazy and key in your SSID and password. Only use WPS for those end devices there is no other option and then turn the WPS off immediately after....then again don't buy a device that forces you to use WPS to get it on the network.

WPS does not cause a performance issue if you do not have some unauthorized person connecting to your network. It is purely a function for those to lazy to key in a password.

Most small consumer switches are pretty much just 1 chip inside. It does not partially fail pretty much the switch stops working completely. The most common failure is not even that chip most time you the power supply fails and the unit does not turn on or boot.

If you did get a partial failure of the switch you would get data errors on transmission. You might see it by ping of the router ip but there is a error counter on the port that I don't remember how to see in windows 10. It is much more likely a cable problem that causes these rather than the switch but even a cable problem is very rare.

You still need to figure out if you are losing the internet itself or if you are really losing something in your lan. You should attempt to log into your router when things are broken. The router might have a log or other messages that tell you what is going on. Just being able to log into the router will also show you if your switches and pc are correctly working

hi Bill,

Upon investigation under your guidance i manage to find that during my hanging problem i observe no RX/TX data on WAN(PON) and the same time there is data on lan port. This info i manage to extract from Web management page. If i could know how i can upload
snap on this blog. Following info appear on the routre WAN(PON) STATUS:

RX Bytes:0
TX Bytes:0
RX packets Error:0
TX packets Error:0
TX Bytes: 0
Tx Packets:0
Tx Packets Error:0
Tx packets Dropped: 0
Tx Packets Collied: 0

i complain to my ISPN but as per there investigation the service is alright. What do you suggest this can be a router malfunction?
Does huge traffic can cause this issue on router??
