Subject: Re: Network Upgrade Option
<=r>

I'm hesitant to of=er opinions since I don't know this vendor or their reliability and=my expertise isn't in enterprise WiFi solutions like Ruckus (tho Br=ce can manage them at Zorro, so they can't be too difficult). =div>

My instinct is to be hands-off since there's ver= little I can do to help from up here, but I *know* no matter what gets ins=alled, I'm going to end up supporting it, so....

1.=We still have no answer as to what is causing the internet to drop i= and out in PB. They're offering a solution of essentially ripping t=e entire network out and starting from scratch — which MAY be the c=rrect way to go — without giving an actual diagnosis. The Cisco &am=; AirPort setup has always had its coverage gaps, but instability wasni,=99t an issue.

Are we replacing everything for the s=ke of "upgrading" or is there an actual problem / solution p=an here?

2. I still don't know w=ere that firewall came from, who installed it, when it was installed, or wh=t its configured to do. That it just showed up out of nowhere and now we ha=e all these problems makes me wonder if it's just not setup correct=y.

3. You're right. Their prices a=e inflated: Ruckus 901-R710-US00 Their price: $ 1,295 ea. Amazon: $750-830&nbs=;

btw the only reason we need these is because the switches th=y've chosen use a different fiber port than the Cisco's

<=iv>4. They=E24040re including a $593 annual monitoring fee, on top of their $1890 in=tallation fee AND their $2945 configuration fee. Plus $420 for "pro=ect management".

I'm seriously underb=lling.

5. Their plan includes "several=separate v-fans" with managed switches... By JEE standards, this ho=se is not that big square footage wise, at most there will be what 5-10 peo=le there?

What POSSIBLE need would there be for 40=9Cseveral" separated virtual local area networks??!! In other words= they want to have more than three networks completely isolated from each o=her, to support MAYBE a dozen devices.

I can see a case for=separating the phones from the rest of the network, but when you start divi=ing WiFi from wired, you have all sorts of unintended problems — su=denly the printers don't show up if you're not on the corre=t wireless network, and the boss can't stream music from his iMac t= the speakers by the pool anymore. Terrible idea for how his networks are u=ed.

## ***

I haven'= had any free time this week at all, but as soon as I can steal away a f=w minutes, I'd like to research the difference in usable range of r=ckus vs. unifi vs. Netgear's Orbi vs. Apple AirPorts vs. eero. =

In 2014 there were 9 airport devices driving the P= network; today there are 7. The Ruckus are supposed to have dramatically w=der range, so I'm wondering why we'd need 9 of them to cove= the main house, cabana and staff house.

Good afte=noon,

I've attached our recommendation for the network upgrade.&n=sp; Normally, it takes about two weeks to get all of the material, th=n the installation will follow shortly after.

We'd need the down payment before we can=order anything. I can pickup a check, we can arrange a wire tra=sfer, or we do take credit cards but there is a 3% service fee. =Let me know what works best for you.
