design a new network

[solferino]

hi guys I am having a lot issues with this network setup and I need some help in configs.
here is a picture for an overview

here are the issues he is facing with this network:
1.everymornning the internet connection drops off after using it for 15 mins . at the same time there are also a lot users connecting and using the internet. frequent internet disruption occurs throughout the day.
2.transfer of file from server pc to another pc is slow as hell after 2 files are consecutively transferred when using the netgear .
setup is as below:
netgear configured as router and dhcp server so that all devices received an ip except the ip phones which have been statically assigned an ip address . no configs have been added to the netgear for connecting the ip phones
users connect to the netgear using wifi for internet access or transfer of files between servers and laptops., connection slow as hell after 1st transfer finished.
so netgear has 2 ssids which all users use for internet .
need some recommendation from you guys for incorporating cisco in this network
there are around 50 users connected max
thanks

Disconnects - sounds like you're overwhelming the Netgear, that type of workload will saturate a Netgear pretty well. But monitor the WAN as well.

Slow file transfers - That could be things such as the limitations of the PC or workstation. Driver issues. Duplex mismatches. Switch problems

What cisco products are you looking into?

Yowsah.... For your slow file transfers... your Dlink hub right after the R7000 is well... a hub and 10/100. Right after that is your Dlink switch (good) but it's also 10/100. I didn't even bother to think about the APs. I'd change the 10/100 hub & switch to at least gigabit switches. Yes, your wiring needs to be good too, if certain wired PCs start to throttle speeds, change the wire if you can, otherwise reduce that connection to 100.

However since it sounds like a SMB, I'd start with swapping that hub out with a gigabit switch.

 

[ch33zw1z]

Good catch razel, I didn't google the models.

The 10/100 switches are getting crushed.

Like others have said, ugrade that Dlink switch to gigabit. And use wired ethernet connections for PC/workstation/Servers/Laptops.

Laptops have ethernet ports, use them.

If the location permits, I would go with a single 32+ port managed gigabit switch to replace both the 916d hub and the des-1016d switch. otherwise just replace each with their gigabit equivalent..

Servers on managed switch should be connected with multiple Ethernet ports configured for link aggregation in order to better handle multiple simultaneous client connections.

File transfers should be done via a hardwired connection if at all possible. Wifi has to share, hardwired does not. (oversimplified answer)

If clients support wireless AC, your wireless N AP is holding you back; Wireless AC is much faster (compare connections via the R7000 to those on the AP; you should see a significant difference)

ok guys , need to replace those existing switches/hubs with gigabit switches but what about the intermittent internet connectivity issues I am experiencing?

I s it possible to subnet this network using the netgear router r7000?

 

[razel]

If you really want to fix this then you'll know that the Internet cannot predict or solve all your problems guessing. You have to try. Also if that is a business or small office, the last thing you want to do is prematurely bring the whole thing down, by re-architecturing. So I'd start with that major pinch point at that hub and continue from there. It's not like buying a switch will be useless later, they can use it as a backup.

 

[solferino]

yeah I need to start getting my hands dirty by layer 1 first and then moving upwards

 

[ch33zw1z]

Pretty much. Upgrades.

hey guys can anyone help me with the config part of the netgear router r7000?
the netgear router has an option for static route , so do u think I need to create a static route to the subnet for voip subnet?

 

[ch33zw1z]

Static route for what exactly? Does voip traffic need to go anywhere in the LAN?

 

[solferino]

voip is for receiving calls and sending calls, I thought maybe I needed to add some config it to the netgear ?

calls are transferred among ip phone internally , that 's it.
can someone explain to me what is this static route option in the netgear router?
I am having a hard time understanding its purpose.

Every networked device has routes.

There are link local routes. They essentially say: "just toss it out via interface X".
Whenever you connect to a subnet (e.g. 192.168.69.0/24), i.e. get IP (like 192.168.69.42)
you also get a route: to members of 192.168.69.0/24 via interface that has address 192.168.69.42

In addition you can have explicit routes to specific (nonlocal) destinations.
For example: to members of 10.10.20.0/24 via 192.168.69.69
The 192.168.69.69 is thus a router that can forward towards 10.10.20.0/24
You do need the link local route in order to send to 192.168.69.69.
These explicit routes are "static".
You hardly ever have them in home.

Finally, there is the default route. Every destination that does not match any link local or explicit route will be delivered to according to the default route.


Why does a device (Netgear) have an option to define static routes? Someone might need that functionality. Most don't.

Is this double NAT? Why isn't VOIP PBX box Yeastar S20 behind the Huawei HG8245Q?

Possibility 1) hooking it in to the Huawei presented connectivity issues due to traversing the netgear
Possibility 2) It was more convenient location wise to connect it that way

 

[mxnerd]

Huawei HG8245Q has 4 LAN ports.

Both Netgear R7000 and YeaStar can be put behind Huawei. R7000 should also be put into AP mode.

Maybe. I would hope the reason it is connected as it is was "on purpose" for a "valid reason" as opposed to "F- it, just plug shit in and get it going"...
Ghetto version of EAPOL???
