 LX_Allen | Hi 👋 there | 12:25:45 |
 Lachezar | So... When I try to bolster OpenWrt to my family, one relative of mine points to TP-Link's mesh devices beeing easy to throw around the house. Does OpenWrt support Mesh? Are there any devices on the market, that can have OpenWrt installed and do the same? | 14:29:16 |
 polymechanos | I’m pretty sure it does, but even if it doesn’t, I think it would be relatively easy to set up something similar | 15:09:59 |

| Lachezar | polymechanos: Mesh is not easy... Sharing authentication session between cells requires cooperation that I am not sure is there OOTB. | 15:14:01 |
| mhnoyes | https://duckduckgo.com/?q=site%3Aopenwrt.org+toh+802.11s&df=y | 15:15:18 |
| mhnoyes | 802.11s is standard | 15:16:39 |

| mhnoyes | Mesh (802.11s) sacrifices bandwidth for convenience. That will change with Wi-Fi 7. It has enough bandwidth that you probably won't notice a performance hit. | 15:35:54 |
| mhnoyes | https://en.wikipedia.org/wiki/IEEE_802.11be
theoretical maximum of 46 Gbit/s | 15:38:17 |
| mhnoyes | For all practical purposes, fiber is the only thing that will satisfy Wi-Fi 7 backhaul requirements.

All previous categories of balanced twisted pair copper cabling supported a Permanent Link Length of 90m (295’) and a channel of 100m (328’). Category 8 has a maximum Permanent Link Length of 24m (78’) and a maximum Channel length of 30m (100’) when supporting 25Gbps and 40Gbps speeds. | 15:48:40 |
| mhnoyes | Note: Cat7 is not an IEEE standard and is not approved by TIA/EIA. | 15:51:49 |
| mhnoyes | * Note: Cat7 is not an IEEE standard and is not approved by TIA/EIA. Use Cat6A or Cat8. | 15:53:54 |
| mhnoyes | For reference 5G cellular theoretical peak download speed of 20 gigabits per second and 10 gigabits per second upload speed | 15:59:28 |
| mhnoyes | This means the likely LAN choke point is the Wi-Fi 7 uplink port. | 16:07:40 |
| mhnoyes | * This means the likely LAN choke point is the Wi-Fi 7 uplink port. It also means there is plenty of excess bandwidth available for 802.11s. | 16:12:34 |
| mhnoyes | Example:
https://www.techradar.com/pro/tp-link-omada-eap690e-hd-access-point-review
The supported WIFI standard is 6E, comprising 4804 Mbps on 6 GHz, 4804 Mbps on 5 GHz, and 1148 Mbps on 2.4 GHz for a total bandwidth of 10.8 Gbps. | 16:20:52 |
| Lachezar | This is $450 for one (https://www.amazon.com/dp/B0C448VPC1) | 16:53:32 |
| Lachezar | These are $130 for three https://www.amazon.com/dp/B084GTH5LL | 16:53:59 |
| Lachezar | * These are $130 for three (https://www.amazon.com/dp/B084GTH5LL) | 16:54:08 |
| mhnoyes | Look at the uplink ports. | 16:54:52 |
| Lachezar | Irrelevant. | 16:55:18 |
| mhnoyes | How so? | 16:56:03 |
| Lachezar | Internet speeds where I would be deploying these would be <100Mbit. | 16:56:36 |
| mhnoyes | That's not the case for lots of people. | 16:57:06 |
| mhnoyes | Even Google is starting to offer 10GbE WAN. | 16:57:41 |
| mhnoyes | So you started giving polymechanos advice? | 16:59:09 |
| * mhnoyes wanders away shaking head. | 16:59:32 |
| mhnoyes | Another bufferbloat test...
