Question: Is the unit N or G
Document: We live on a farm, and wanted wireless internet coverage across our farmyard. On first glance, this appeared to be the perfect product. The product arrived quickly, and the instructions for setup were clear. However, I had three problems with the product which led me to send it back.1) The range was less than the range of our existing wireless-N router.
The Ayrstone Ayrmesh Hub works in an excellent manner as advertised. You can not go wrong with this unit. If you have alot of trees, metal, concrete blockage between Points A and B, I also recommend a unit to boost the reception. Thank you for this needed product. Kudos to all.
I also get strong signals for the two Roku devices (for streaming Netflix) - one on the basement and one out in the garage. I couldn't be more pleased. I'm not a techy, and setup was a bit complicated, but I managed just fine. If you're having a wi-fi signal problem, this unit, though somewhat pricey, should solve your problem.
Intended to use this as a second Access point off the DSL modem. Initial impression was not good but that turned out to be aa modem problem. Before the exact problem was identified Ayrstone email support sent out a replacement at no charge including a prepaid return label to return the defective unit. When the replacement was installed, and we had the same issues, that's when the modem was replaced. Thereafter the original unit worked just fine.
I am a computer, wifi, network and phone system tech. I purchased two of these units for a 70 site Motorcoach resort in the mountains of Virginia. One Ayrstone, the gateway, is located at the front of the resort and it is mounted on the roof of our clubhouse. Because the back of the resort is uphill and is higher than the clubhouse roof, I installed the second unit at the very back of the resort about 350 feet away from the gateway.
We have been looking for a long time for a WIFI setup, that would work well at our resort. We have a dozen Fireplace Cabins, 16 unit Village INN, General Store, 31 spot RV Campground, Restaurant and lots of open space. The resort is spread out over about 20 acres almost a half mile in length, the Ayrmesh hub looked like it could do the job, so I ordered one.
The installation couldn't have been easier (except the climbing on the roof part), and we have excellent signal strenth nearly 1/4 mile away from the tower through a significant stand of trees! We were sure we'd need a second unit to strengthen the connection, but not so. An installation issue on one of the three laptops we connected was handled in one very pleasant five-minute call with a skilled technician. Highly recommend this product and company!
I installed this to share Wi-Fi with a second house on a hill 770' away. The signal got to the house no problem but since it's up a hill I had to install a second one at the edge of the hill to provide good coverage inside the house since it is shielded by the angle of the grade. Added second unit and added it to the website, waited about 15 minutes and everything just worked. I'm impressed.
Customer service is outstanding. My first unit was defective and they sent me another one proptly. I live in a large log home with thick walls and could not get wireless dependably throughout the house. Now I have good signal with no interuptions, but not full signal at the far reaches of the house as I'd hoped, however it is giving me uninteruped use that I have never had before. and I am glad I have the unit.
Netgear WIFi unit in the house cannot get outside because of aluminum siding and metal roof, great RF shield, bad for communications. Bought two Arymesh units thinking I would need one in the house window to send and then one in the shop window to receive and distribute internally, since the shop has metal siding and a metal roof. I ended up installing the Ayrmesh 20ft up on my tower.
Answer: My review was on the G. I have however updated to the N and am very satisfied. The company is great to work with, and I highly recomend the unit.
