Currently I have 1gig Spectrum internet at my home. I’m coming out of the modem to the Spectrum supplied Sagemcom SAX2V1s Wifi6 router, which runs my house (1800sqft).  Using the router ports, I’m running approximately 175’ to an outside building. Where I’m connected to Omada ES206GP. This goes to an EAP610. Then from the ES206GP, I am running another line approximately another 75’ to a 2-story garage. Here I have another PoE switch feeding two more EAP610s, one in the garage and one upstairs in the apartment. I do have the EAP’s on separate channels on the 2.4ghz and reduced the TX power in the garage. For the last few days, it appears my internet has been dropping for a few seconds. The legacy seems slow. When I run speed test everything checks ok.  I’m not sure if I’m having bandwidth issue or if the Sagemcom router isn’t cutting it. I recently added the 2^nd EAP in the upstairs apartment.  Now may be a good time to mention that I do not have a ton of knowledge regarding networking.  I would like to add another ES206GP and an OC200 in the house, to help with roaming.  I would like suggestions on a router or if anyone has other suggestions for my setup.  I thought about the ER706W or maybe just another TPlink router. 

Thank you for any and all suggestions
