Not wishing to jinx it, but the situation looks to be in a much better place. I think a combination of configuring the core switch to be priority 0 for spanning tree, preventing the Chromebooks from talking to each other (and other devices on the LAN) and bypassing an aging DC on the Chromebooks has helped. Thank you all for your valuable input, much appreciated!

It would be 32 version of the Zioxi trolley I'd need to talk to finance regarding cost.

Ah, a 9 hour round trip for an iPad trolley is possible a little too long!

I notice they've pulled update 61...

No, not a reference site I'm afraid.

Where are you based?

We just have blooket.com in a category set as allowed and it seems to be working fine. Is there anything 'above' it in the policies tables that could be blocking it? For example, it's also going to be in the Educational Games and Education and Reference categories.

On release 60, so maybe I'll hold off on that update! Smoothwall may or may not be the culprit, I'm getting a new and improved box over the next few months, so I'm hoping that will confirm one way or the other.

Thanks for the tips. For anyone else wondering how you make your core switch the root bridge for spanning tree, I found this guide very helpful (for HP Switches) One of those things I felt I should have picked up over the years... I'm going to remove my last 100Mbs switch over the next few days to see if that helps, it's connected at 1GB, so shouldn't slow the network, but everything helps.

If you happen to be using Bromcom, the integration with O365 is excellent and highly recommended.

All HP Switches The only config on them is the vLans and spanning tree enabled (so no QoS defined)

Not, not just the wired, everything runs slow. An updated Network Diagram is in the works, but essentially we have one core switch and 14 edge switches connected via Fibre with 52 Access Points all connected at 1Gb.

I don't disagree, but if I can't maximise a 1Gb network, 10Gb isn't going to help!

That would explain a lot... Thanks! There's a mode on Meraki (NAT mode) that might solve that particular issue.

Thanks, will take the plunge this afternoon!

Sorry, should have added, looking at the traffic on the Smoothwall, internet traffic is around 100-200mbs, it doesn't hit peak bandwidth (800mbs) when network issues arise. - - - Updated - - - I suspect you're right, I'm just not great at interpreting Wireshark results. I guess it's time to 'get gud'.

All devices are 802.11ac minimum, so connecting on both channels. It also impacts on wired devices as well, which shouldn't be affected by wireless channel congestion...

Not sure where to place this question as it could be any number of things, but wired networks seemed the best fit. Something is causing a bottleneck on my network that restricts bandwidth to around 150mbs: The internet line is 800mbs and can absolutely deliver that speed. The network backbone is, at minimum, 1Gbs fibre The core switch is newly installed over the summer and can handle upto 10Gbs throughput Wireless traffic is vLanned off However, once the students turn on their Chromebooks (around 700 of them) the network's internal and external traffic slows to an absolute crawl. Looking at the Wireless management in Meraki, when Wireless network traffic is around 0-110mbs, everything is fine, when it reaches 120mbs+, this is when the problems occur. I could understand the problems if our wireless network was reaching 500-600mbs, but surely the network capacity is 800mbs, so I shouldn't be having the issues we're having at such low levels? I've removed as many switches as possible, and we only have one IT Suite, so the vast majority of our traffic is wireless. Inter Server speed is around 500-800mbs. When monitoring the Core switch ports, the capacity of any of the uplinks never exceeds 20%. I've been trying to resolve this issue for months, and so far the only method that has worked is to limit the bandwidth of the Chromebooks to a low level so it doesn't saturate the network. But I feel that I'm not getting the most of this network! Any ideas on either what could cause a bottleneck and/or how to identify a bottleneck on a network?

I think an awful lot of our linked documents are legacy, so in an attempt to keep Bromcom 'fresh' I've not been asked to do that (yet!).

We're keeping an archive of our SIMS server. The predominant reason is for any documents that have been attached to students as they don't carry over. I'll guess we'll find out what else is missing as we go along!

Just received the BBC Radio adaptation of The Lord of the Rings as a birthday present from my lovely wife this morning. Haven't listened to it for decades as I originally had it on tape. Still think it's the best adaptation Not sure about the TV Series, I'm sure it will go on the list along with everything else, but Sandman is next!

Some pretty good deals on Chromebooks: https://www.amazon.co.uk/deal/e8f1acc7/ref=cg_banner_1c1_w?restrictions=n:29409254031&pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=slot-1&pf_rd_r=82SK40E8TDQCES4WSGFC&pf_rd_t=0&pf_rd_p=4c3cb073-2982-40ce-a489-3cb2340d140e&pf_rd_i=e8f1acc7
